CHAPTER ONE

1.1. Introduction

A mobile device, which is also referred to as a handheld device or handheld computer, is a

pint-sized computing device. Mobile devices usually come with a touch or non-touch display

screen and sometimes, even a mini keyboard. There are many types of mobile devices; the

commonest ones are mobile phones, smart phones, PDAs, pagers and Personal Navigation

Devices. PDAs and smart phones are among the most preferred mobile devices, which offer

all the conveniences of a personal computer, along with a very small form factor.

Although mobile phones have taken over our current society, they have been around for

several decades in some form or another. Beginning in the late 1940s, the technology that

would later be used in today’s cell phones was created and the idea of a mobile phone was

introduced. This cell technology was first used in mobile rigs which were mainly used in

taxis, police cars and other emergency vehicles and situations. Truckers also used a form of

this technology to communicate with each other. The first mobile phones, referred to as First

Generation or 1G, were introduced to the public market in 1983 by the Motorola Company.

These first mobile phones used analog technology which was much less reliable than the

digital technology we use today. The analog phones also had a great deal more static and

noise interference than we are accustomed to today. The main purpose of this First

Generation technology was for voice traffic, but consumers felt insecure about people

listening in on their conversations. During the 1990s, great improvements were made in the

mobile phone technology. These phones used Second Generation, or 2G technology. In 1990,

the first cell phone call was made using the new digital technology that became characteristic

of this era. The Second Generation cellular phone technology was faster and much quieter

than its analog predecessor. As a result, it became even more popular than previous models,

too. The new technology also made them capable of being smaller rather than the large

briefcase-sized units from the 1980s.The Third Generation technology, or 3G, is what many

people currently use in their digital cellular phones today. This technology was created very

soon after the excitement that the 2G technology created. This new technology is not only

capable of transferring voice data (such as a phone call), but it is also able to transfer other

types of data, including emails, information and instant messages. There are currently plans


2

in place to develop a Fourth Generation – 4G – technology. Goals for this new set of

standards include a combination of technologies that will make information transfer and

internet capabilities faster and more affordable for cellular phones.

A mobile application (or mobile app) is a software application designed to run on smart

phone, tablet computer and other mobile devices. They are usually available through

application distribution platforms, which are typically operated by the owner of the mobile

operating system. A mobile operating system (OS) is software that allows smart phones,

tablet Pcs and other devices to run applications and programs. A mobile OS typically starts

up when a device powers on, presenting a screen with icons or tiles that present information

and provide application access. Mobile operating systems also manage cellular and wireless

network connectivity, as well as phone access. Examples of mobile device operating systems

include Apple iOS, Google Android, BlackBerry OS, Nokia’s Symbian, Hewlett-Packard’s

webOS (formerly Palm OS) and Microsoft’s Windows Phone OS. Android is one of the most

popular Linux based mobile operating system.[1]

1.2. Background

The mobile phone device is a very important communication tool as it was built to enhance

social contacts and network while enhancing business productivity. The mobile phone

enables us to be on time during appointments. It also helps in verifying the degree of

temperature to enable us chose appropriate dress code for the day. It keeps us informed on

current events because of its connectivity to the internet. It relaxes it also when we play

games with it or listen to music through it. The mobile device can provide the information

about something and also it detecting the location of the user.

Today, a mobile application plays a great role in our day to day activities. Tour Gondar

application is a city guide mobile application which is run in the smart phones. This

application provides basic information about the services which reside Gondar town like

Hotels, Restaurants, Attraction places, Banks, Tour and Travel agents and Health centers.

The application informs the current events in the town and also it detects the current location

of the users.


3

1.3. Statement of the problem

Gondar is one of the oldest and historical town in Ethiopian history. In this town there are

money Attraction and Historical places, Hotels ,Restaurants, Banks, Health centers and Tour

and Travel agents and also many events are happen in this town like the great epiphany

ceremony (carnival). But the people which are living in this town and also the visitors cannot

access the information about the service providers and events easily. More specific problem

listed as follows:

User cannot access well organized information at anywhere about service provider

like Hotels, Restaurants, Attraction and Historical places ,Banks, Health centers and

Tour and Travel Agents.

User cannot get information about service provider for 24/7 hours.

When there is a new event(like carnival ceremony) happen in the town the user must

be wait until announced and post in mass media.

There is no a mechanism a visitor to detect the current location.

Manually system needs more human power and time.

1.4. Objective of the project

The general and specific objectives of the study are described below.

1.4.1 .General objective

The general objective of this project is to developing a city guide android mobile

application.

1.4.2 .Specific objective

In order to achieve the general objective of this project, the following specific objectives are

addressed.

The system provide information about service provider either in Amharic or English

language

The system detect the current location of the user,

The system provide new update information about events like celebrity;


4

The system also provides a city map to user to search a point of interests like

Attractions places, Hotels and Restaurants.

1.5. Scope of the project

Tour Gondar mobile application is software application which is run only in smartphones and

performs the following activities:

The application gives information about the types of service which is provided by

service provider.

The application provides a working day, time and location of service providers.

The application provides new updated information about service providers and

events.

But the application does not include the following activities:

The application doesn’t provide any information about services provider which is

located outside of Gondar town.

Tour Gondar application is not operates other language rather than Amharic and

English languages.

1.6. System Development Methodology

Since the entire project requirements are not well known in detail initially, the development

team chooses prototype system development methodology to develop the new system. The

basic idea of prototype model is that a prototype build, test, and then rework as necessary

until an acceptable prototype is finally achieved from which the complete system or product

can now be developed. It is an iterative, trial-and-error process that takes place between the

developers and the users. The most significant advantage of using prototype system

development methodology is listed as follows:

Users are actively involved in the development.

Errors can be detects much earlier.

Quicker user feedback is available leading to better solutions.

Missing functionality can be identifying easily.

Confusing or difficult functions can be identifying.


5

Since in this methodology a working model of the system is provided, the users get a

better understanding of the system being developed.[2]

1.6.1. Investigation (fact-finding) methods

For gathering information to our project we use different methods.

Observation: Observation is one of the most important methodologies to gathering

information by physical going to the place and looks how the current system. It can

be very difficult for humans to explain what they do or to even describe accurately

how they achieve a task, so observation very crucial to gathering information.

Interview: Interview is another important methodology to gathering information by

asking someone a set of questions. It helps us to get critical and important

information about the overall view of the current system.

Document analysis: This is also another information gathering methodology by

referring the document of the existing system.

1.6.2. System Development Tools

1.6.2.1. Hardware

The system needs different materials to develop the mobile application and to run the system

in the real world, the basic hardware are:

Personal computer(PC)

Android platform mobile

Flash disc

Digital camera

1.6.2.2. Software

We use the following tools to develop the mobile application:

Eclipse (IDE)

MySQL

Apache


6

Edraw-max

Adobe Photoshop

Microsoft Word

1.7. Significance of the project

At the end of this project, the application will raise the following significance for the users

and the town.

The user can access organized information about services at anywhere and at any

time.

The users (visitors) can easily detecting the current location.

The user can find the services in a simple user interface.

When we develop the mobile application there is some significant role in developing

technology by making the society more interact with technology, this leads to the

Gondar town to shift one step in technology.

1.8. Beneficiaries

The most beneficiaries are:

User: when the users use this mobile application it saves their time and money.

Town: it will enhance the development of the town in the side of technology.

CHAPTER TWO

2. Requirement Analysis

2.1. Introduction

Requirements analysis, also called requirements engineering, is the process of determining

user expectations for a new or modified product. These features, called requirements, must be

quantifiable, relevant and detailed. In software engineering, such requirements are often

called functional specification.

Requirements analysis is critical to the success of a systems or software project. The purpose

of Requirements Analysis is to obtain a thorough and detailed understanding of the user

needs and to break it down into discrete requirements, which are then clearly define, review

and agree upon with the Customer Decision-Makers. Requirements Analysis provides the

foundation for the desired product or services. [4]

2.2. Current System

2.2.1. Major function of current system

The major functions of the system that are currently available in Gondar town are providing

information manually about the service providers like Hotels, Restaurants, Tour and Travel

agent, Banks and Health centers. Other function of the current system is providing

information about events manually. Bazars, pamphlet papers and mass media are using to

advertising the town. Generally the current system uses a manually system.

2.2.2. Problem of existing system

As we have observed the existing system it is not preferable for the user since everything is

manually. As mention above the current system providing information about the service

providers and events but it is not attractive for the users and it needs more human power to

perform the activity. And also the way of advertising the town cannot address many people.

The major problems which are found in the existing g system listed as follow as:

Availability: The current system which is existed in Gondar town is not available at

anywhere and at any time. The system does not easily providing information about


9

the service providers to the user when the user is located outside of Gondar town and

also the system doesn’t work for 24/7 hours.

Performance: The other problem which is resided in the current system is

performance. We are measuring the performance of the current system in terms time.

The time took by the current system to proving information about the service

provider to user so slow.

Data Storage mechanism: The data storage mechanism which is used by the existing

system is manually. The current system used more stationary materials like papers

and pen frequently to store data. Because of this the current system spent more cost

for data storage mechanism.

Efficiency: The other crucial problem which is found in the existing system is

efficiency. We are measuring the efficiency of the current system in terms of

resource: human and time resources. The existing system needs more human power

and time to perform the task like advertising, announcing new information and store

data.

Security: Since the current system used manually system it is easily expose to

security problem. The existing system used hard copy document to store data and it

may be stole the information by unauthorized user easily and it cause a serious

problem.

2.3. Gathering Information

Different fact finding techniques were used to gathering information about the current

system. It is the fundamental activity for the development of the system. Without them data

modeling cannot be constructed. In order to know how the existing system work and what

problem are there we have been using the following fact-finding techniques.

Interviewing

Observations

Document analysis


10

2.3.1 Requirement Gathering Methodologies

To develop the new system we have to collect information, to collect information we use

different methodologies.

Observation: The development team visiting and take look how the manual system

works.

Interview: The development team interviewed administrator of Gondar town about

how the user gain information about the service provider which available in the

town, what is working time and days of the current system , what kind services are

provided by the current system ,what kind services are not provided by the current

system and also ask the challenge which is found in the current system and we

interviewed manager of tourism office about the general working system of tourism

in Gondar town and also we interviewed some people about how much the current

system is effective.

Document analysis: The development team also referring the document of the

existing system.

2.3.2. Result Found

After interviewing, observing and analyzing of the current system, the development team

found some results those are listed as below:

The current system provide information about service providers manually,

The current system works from Monday to Friday for 7 hours in each day,

The current system provide information about attraction and historical places

manually and

The current system needs more time and human power.

2.4. Proposed System

2.4.1. Overview

We would like to create a mobile city guide application. Users of this application will be able

to search services, historical places and other points of interest by using two type of interface:

either a categorized list or by viewing a map. Users can also see more details of a point of

interest when they select it, like a describing text.


11

2.4.2 Functional Requirement

It is a function or features that must be include in the new system to satisfy the user needs

and also be acceptable to the user and solve the problem in the current system.

The functionality of this system are:

The system must provide the working time, days and location of the service

providers.

The system must provide a searching mechanism to the user to find information about

service providers.

The system must providing information in either Amharic or English.

The system must provide new updated information about service provider and events.

The system must provide a map view to users to find the points of interest.

2.4.3. Non-Functional Requirement

It deals with the performance, time, cost and so on. It also describes the importance that is

not directly related to the system.

The non-functionalities of the system are:

The user can access the information about the service provider with a second.

Easy user interface to communication with the user.

The user can access more relevant and reliable information.

The user can access information at anywhere for 24/7 hours.

2.4.3.1. User interface and Human Factors

When conceptualizing the mobile applications user interface, there are a few things that you

should keep in mind. Some of the basic things such as clarity of interface, consistency from

one view to the next, and making sure that size and uniformity user interface element .

The user interface of mobile application must be easy for the user to use without any

ambiguity. Tour Gondar city guide mobile application having attractive list view, consistent

user interface and few and uniform buttons. Even if the interface is easy to use the customers,

there will be some difficulties in understanding some part of the system like how to use and


12

accessing the system. So the user must have some level of experience to accesses and use the

system easily and effectively such as:

The user must have knowledge about how to use the smart phone

2.4.3.2. Documentation

Tour Gondar city guide mobile application provided two documentation which helps to the

user help menu and technical documentation .The help menu providing information to the

user how to use the application. The system might need to be maintained and modified in the

future therefore the maintainers will be provided with technical documentation which are the

analysis, design and implementation documents.

2.4.3.3. Hardware consideration

Tour Gondar City Guide application is deploy in Android 4.2.2 and late versions because

this are the latest’s version for android mobile phone and most people having this versions in

their mobile phone.

Version: Android 4.2.2 versions

Processor: 1GHZ

Memory: at least 512RAM

2.4.3.4. Performance characteristics

The user to access information about the service provider from server it takes only a second.

Since the information is accessed from the database, the new system can support one

thousand users at time and the user can use the system efficiently.

2.4.3.5. Error Handling and Extreme conditions

When the user make an error or extreme condition like that is not allowed by the system, the

system handle error or extreme condition by giving or show an error message and also alert

message to user.

The extreme condition that may occur in this system is:

Out of range(when the user out of Gondar city),the system doesn’t detect the current

location of the user


13

2.4.3.6. Quality Issues

The new system is reliable, robust compare with the current system and also when we

observe the current system it’s not always available anywhere and anytime as the new

system.

Availability: The new system providing service to the client without concerning the locations

of the user and also it works for 24 hours.

Reliability: The user of the new system can access more relevant and reliable information

about the services and also it detect the current location accurately.

Robustness: The ability of error detecting of the new system more efficient than current

system. Since new system is based on client server architecture when error occurred we just

concerning manly on server side. For this reason we are saving time to detecting error.

Content Richness: The new system providing rich information about Hotels, Restaurants,

Attraction and historical places and events in the town.

In case of our new system user involvement in the development processes is vital

requirement for the quality of the system.

2.4.3.7. System Modifications

In the future the system can be modified in order to have the following extra features that are

not implementing now.

This can be listed as:

Enabling the users to detect the current locations using Wi-Fi rather than GPS.

Enabling the users to viewing offline map rather than online map.

Those new features can be implemented by another programmer or by the team in future.

2.4.3.8. Physical Environment

The System is deploy in each individual smart phone. In order to detect the current location

of the user the system need protection from external factors like those things that does not

make clear line between the device and the sky since the GPS system need a clear line

between the phone and Satellites to detect the location of the user.


14

2.4.3.9. Security Issues

To protect the application from unauthorized user and malicious attack, we will concern the

security issues into two perspectives: from client and server perspective.

Client perspective

Compared with personal computers or servers, mobile devices store much more sensitive

personal information and are thus attractive targets for attackers seeking financial gain.

Because these devices are always online and have a restricted user interface, it is easier for

attackers to hide their malicious activities. This special issue aims to present high-quality

articles describing security algorithms, protocols, policies, and frameworks for applications

running on modern mobile platforms such as Android, iOS, and Windows Mobile. Security is

a major part of any Android device. Since the system will be hosted on the user smart phone

the user will provide security tools such as antivirus to protect the applications.

Server perspective

An electronic announcement board where authorized users can publish and/or read

announcements. There two types of user, author user and read-only user. The rights of a user

are determined by its type: An author user has the right to create new announcements and to

modify or delete announcements authored by himself. A read-only user has the right to read

all announcements. The announcements are centrally stored in a database server and the

author users and read-only users, can use mobile devices to perform their application related

operations remotely. The core of the application is built on mobile database technology. So

by giving such kind of privilege to the user, we can protect the data in database server from

unauthorized user.

2.4.3.10. Resource Issues

The system has a resource that requires the following performance characteristics:

The smart phone must have enough memory space to process the application.

The smart phone must have high processor speed.

The phone must have a latest version of android OS.


15

2.5. System Model

A system model is the conceptual model that describes and represents a system. A system

comprises multiple views such as planning, requirement analysis, design, implementation,

deployment, structure, behavior, input data, and output data views. A system model is

required to describe and represent all these multipleviews.

System modeling is intended to assist in developing and maintaining large systems with

emphasis on the Construction phase. The idea is to encapsulate complex or changeable

aspects of a design inside separate components with well-defined interfaces indicating how

each component interacts with its environment. Complete systems are then developed by

composing these components. System modeling can increase reliability and reduce

development cost by making it easier to build systems, to reuse previous built components

within new systems, to change systems to suit changing requirements such as functional

enhancement and platform changes, and to understand systems. In this way, a system model

can satisfy different requirements such as documenting the system, providing a notation for

tools such as consistency checkers and can also be used in the design stage of system

development.[2]

Thus, system modeling is used to ensure that a developing piece of software evolves in a

consistent manner and that the task of integrating software components is simplified.

Use case diagram is a visual depiction of the different scenarios of the interaction between

actor and use case. An actor is an idealization of an external person, process, things that

interact with the system or subsystem. A use case is logical description of the slice of the

system functionality.[3]

2.5.4.2. Class Modeling

The purpose of the class diagram is to model the static view of an application. The class

diagrams are the only diagrams which can be directly mapped with object oriented languages

and thus widely used at the time of construction.[3]

Sequence Diagram

A sequence diagram is an interaction diagram that shows how processes operate with one

another and in what order. It is a construct of a Message Sequence Chart. A sequence

diagram shows object interactions arranged in time sequence. It depicts the objects and

classes involved in the scenario and the sequence of messages exchanged between the objects

needed to carry out the functionality of the scenario. Sequence diagrams are typically

associated with use case realizations in the Logical View of the system under development.

Sequence diagrams are sometimes called event diagrams, event scenarios

A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects

that live simultaneously, and, as horizontal arrows, the messages exchanged between them, in

the order in which they occur. This allows the specification of simple runtime scenarios in a

graphical manner.[3]

CHAPTER THREE

3. System Design

3.1. Introduction

Systems design is the process of defining the architecture, components, modules, interfaces,

and data for a system to satisfy specified requirements. The System Design Document

describes the system requirements, operating environment, system and subsystem

architecture, files and database design, input formats, output layouts, human-machine

interfaces, detailed design, processing logic, and external interfaces.

In this chapter we try to discuss the design part and also we see the architecture part. After

this has been done, the analysis was completed using different UML diagram. System design

is the first step to get into the solution domain. In this document we will try to describe the

design aspect of the new system.[2]

3.2. Current software architecture

In the city currently there is no any software in use to guide the city for the users.

3.3. Proposed software architecture

3.3.1. Overview

We try show the bird’s eye view of the new system so that, the software architecture for each

subsystem functionality will be the following.


43

Figure 16 Overview of the new system

3.3.2. Subsystem decomposition

Component diagram is a special kind of diagram in UML. It does not describe the

functionality of the system but it describes the components used to make those

functionalities.

So from that point component diagrams are used to visualize the physical components in a

system. Component diagrams can also be described as a static implementation view of a

system. Static implementation represents the organization of the components at a particular

moment.

Use component diagram to partition a system into subcomponents. The main subsystem of

the system list as follows:

User Interface subsystem

Database subsystem

Account Management subsystem.[3]


44

Figure 17 Components diagram for subsystem decomposition


45

3.3.3. Hardware/Software mapping

Deployment diagrams are used for describing the hardware components where software

components are deployed.[3]

Figure 18 Deployment diagram for hardware/software mapping


46

3.3.4. Persistent data management

Persistence modeling is used to communicate the design of the database, usually to the

developers. It is also used to describe the persistence data aspect of the system.

3.3.5. Access control and security

In this new system different actor have access to different functionality and data. Who can

access what is by using an access control matrix is describe in the following table. The

following table describes an actor who is involved in the scene and the possible benefit

assigned to the actor.

Actor Privilege

User requestToView();

Administrator uploadData();

updataData();

deleteData();

Table 16 Access control and security


50

3.3.6. Subsystem services

In this section try to cover the main subsystems that are used in the system and the service

provide by each subsystem. Those are:

User interface subsystem: this subsystem used to interact the user with system and it

is majorly connected with the database subsystem for displaying up to date

information that is stored in database.

Database subsystem: this subsystem is used to perform the task that is performed by the

administrator. The tasks that are performed in the database are updating information such as

deleting and uploading information.

Account management subsystem: this subsystem is used to perform user management

and validating there account.

3.3.8. Package

Package diagram is UML structure diagram which shows packages and dependencies

between the packages. Package diagram enables you to gain a high level understanding of the

collaboration among model elements through analyzing the relationships among their parent

package. This also helps explain the system's architecture from a broad view.[3]

CHAPTER 5

5. Conclusion and Recommendation

5.1. Conclusion

In this project, we presented the design and implementation of a mobile application called

Gondar City Guide, with which mobile users can get valuable information on different

Attraction places, Restaurants, Hotels, Healthy center, Banks, Police stations and Tour and

Travel agent in Gondar town with more ease at anywhere and anytime. Users can get basic

information about service providers in text and pictures. In particular, this application can

provide users location-based information of a Gondar town which can be browsed or queried

through a city map. Visitor can get current event information automatically when events are

occurred in Gondar town.

5.2. Recommendation

The team that developed this project recommends the following point for the best

implementation and installment of this project.

The user should be familiar with smart phone.

The government should facilitate internet access all over the country and support

peoples to learn and use it.

The application data should be update regularly by the an authorize person.

Appendix A Glossary

Activity:An Activity is an application component that provides a screen with which users

can interact in order to do something, such as dial the phone, take a photo, send an email, or

view a map.

User interface:the means by which the user and a computer system interact, in particular the

use of input devices and software.

Password:is a secret word or phrase that must be used to gain admission to something.

Unified Modeling Language (UML):Unified Modeling language (UML) is a standardized

modeling language enabling developers to specify, visualize, construct and document

artifacts of a software system.

Use case diagram:Use case diagrams are a set of use cases, actors and their relationships.

They represent the use case view of a system.A use case represents a particular functionality

of a system.

Activity diagram:Activity diagram describes the flow of control in a system. So it consists

of activities and links. The flow can be sequential, concurrent or branched.

Class diagram:Class diagram represents the object orientation of a system. So it is generally

used for development purpose. This is the most widely used diagram at the time of system

construction.

Sequence diagram:A sequence diagram is an interaction diagram. From the name it is clear

that the diagram deals with some sequences, which are the sequence of messages flowing

from one object to another.

Data dictionary:A data dictionary is a file or a set of files that contains a database's

metadata. The data dictionary contains records about other objects in the database, such as

data ownership, data relationships to other objects, and other data.
