ABSTRACT

Student Accommodation system by manual way is tedious process, since it involves work load and time

consumption. In this system, we can easily manage the Accommodation information. Landlord Details, room

details, student records, easy way of room allocation and hostel Rules and Regulations.

The main feature of this project is easy to allocate for the student and also easy to access the Accommodation

information and the Registrations. This project is carried out using Visual Basic as front end and SQL as back end.

Introduction

As the name specifies Student Accommodation system is software developed for managing various

activities in the University. And the Student accommodation system helps the students to find

properties to rent in the city which they are studying.

For the past few years the number of university are increasing rapidly. Thereby the number of hostels is

also increasing for the accommodations of the students studying in the University. And hence there is a

lot of strain on the person who are running the Accommodation center and softwares are not usually

used in this context. This particular project deals with the problems on managing a Accommodation

system and avoids the problem which occur when carried manually.

Identification of the drawbacks of the existing system leads to the designing of computerized system

that will be compatible to the existing system with the system which is more users friendly and more

GUI oriented. We can improve the efficiency of the system, thus overcome the drawbacks of the

existing system.

1. Data redundancy can be avoided to some extent2. Data consistency

3. Easy to handle

4. Easy data updating

5. Easy record keeping

6. Backup data can be easily generated

Finally I made a project on the Student accommodation System, which is an attempt to automate the

existing Hostel. This project gives us the complete information about the Accommodation Land Lord

information, Rent Details, Important telephone #,, and the accommodation rules ..

Also the developed system is the best way to decrease the work load and saves time required in

creation, updating, removal or view within records.

Introduction to the Software Tool

The visual part refers to the method used to create the graphical user interface (GUI). Rather than

writing numerous lines of code to describe the appearance and location of interface

elements, you simply drag and drop pre-built objects into place on screen. If youve ever used a drawing

program such as paint, you already have most of the skills necessary to create an effective user

interface.

It revolves around ready-made objects and it is event-driven that is all the activities in a

program are triggered by one event or another. Each object has its own properties, determining its

position, size, color, appearance and nature of its text and much more. Each object also has its own

event-handling procedures.

Visual basic knows what a button is and how it works? It also works how to handle images, menus,

dialog boxes, drive and directory list and much else. The programmer does not have to

write code to trap these events the system does that automatically because the program

code runs in response to events. The flow of execution is not as fixed in a traditional program.

Operations do not have to follow a set of sequence and can be easily interrupted, suspended or

abandoned. The process of program design reflects the nature of the system. You begin by the screen

layout events and then any necessary code to co-ordinate the whole program.

Introduction to Sql Server

Server-side data access is critical to all real-world applications. This section introduces you to the SQL server data

access through Web Forms. Microsoft SQL Server is a Relational Database Management System (RDBMS) that

issued to store and organize related data the collection of related data is called a database. Microsoft SQL

Server is based on the client/server architecture, in which data is stored on a centralized computer called a

server.Other computers, called clients,can access the data stored on the server through a network.

The client/server architecture prevents data in consistency. You can access data stored on a SQL server through

Web Forms. To do so, you can create Web applications that have data access controls. These data access Web

controls present the data in a consistent manner irrespective of the actual source, such as Microsoft SQL Server.

Therefore, while creating a Web application, you do not need to worry about the format of the data. However,

before you can access or manipulate data from a SQL server, you need to perform the following steps in the

specified sequence:

1. Establish a connection with the SQL Server.

2. Write the actual command to access or manipulate data.

3. Create a result set of the data from the data source with which the application can work. This result set is

called the data set and is disconnected from the actual source. The application accesses and updates data in the

data set, which is later reconciled with the actual data source.

SCOPE OF THE PROJECT

EXISTING SYSTEM

The existing system is a manually maintained system. All the Hostel Student details are entered into recordsmanually.

Separate records are to be maintained for the details of each student, Fee details, Room Allocation, Attendance

etc. All these details are entered and retrieved manually.

In such a system, if a particular students is to be known, first track the identification number, then look in for the

Room number he is stay in and based on that check for the Attendance and Refund record or related record.

Limitations of existing system:

As described earlier the existing manually maintained system is subject to many errors and disadvantages. Themain disadvantages are as follows:

1. Time Consuming: Retrieval of required data takes much time as the data is put at several places and one

has to browse through many files to get even a small piece of data. Also the updating process,

preparations of reports manually is all very time consuming.

2. Inaccuracy: Maintenance of vast data manually has many chances of inaccuracy of data.

PROPOSED SYSTEM

The Proposed system is the computerized version of the existing system. It rectifies most of the pitfalls of the

existing system and maintains databases of all the entities participating in the system.

Computerization provides easy and quick access over the data. Authorization schemes like giving passwords,

encoding data can be used to maintain data security. Also data cannot be lost due to natural disasters.

Visual Basic has been chosen for this project because Visual Studio Application are portable across a wide range

of platforms and operating systems. Visual Studio IDE controls provide tools to develop the package to be

efficiently used by the end users.

Criteria( P15.1.1)

Identify Various Visual Objects You Have Use for the Application

Visual objects

In Visual Studio there are lots of Visual objects we can use, whatever we need for our program. Those visual

objects we can easily identify and we can handle those objects very easily, not like other programming languages.

Just we can drag and drop to the frame. So when we consider about its benefits, it gave lots of facilities to usersor programmers.

Student Accommodation System also there is lots of objects I have implemented, such as

1. Textbox,

2. Labels,

3. Frame,

4. Buttons,

5. List box

6. Picture Box

7. Menu Stripe

8. Progress Bar

Those objects I used according to my needs. Each and every objects are doing specified such works, so according

to users purpose we can choose those objects.


9/74


9 | P a g e

Visual Objects Description with the Screenshots

Label

This is the Student Registration Form; Here I have use Several Labels to Display to Figure out the Correct Textbox

to Enter the Data

Label 1

Display Text - Student Registration

Using these labels we can show what ever written formatted phrases. The labels can come in all widths, sizes and

colors. In VB program there different situation we can use this labels according to the users need. Such asituation we can use this labels as text area, but only we can read only

Text Box


10/74


10 | P a g e

The text area as we know, writing area of a program, but through this textbox we can full fill several purpose,

such as in this program we writing in side this textbox, and I am pressing button I can retrieve records from

database and again I can edit my records

Menu Stripe

1. Login

2. Rules and Regulations

3. Registration

4. Employee \details

5. Accommodation

6. Accommodation Locations

7. Reports

Menu stripe is the very important in this student accommodation system. Because user doesnt want go and click

each and every form.. Simple can used the menu form and can press whatever they needed accordingly likewise

student registration, landlord info, accommodation reg... All were properly linked to the forms and database so

menu strip Is having a very important place in this

Buttons

1. New

2. Save

3. Search

4. Edit

5. Clear

6. Delete

7. Exit

The buttons are very important in a program, because using this buttons only we Can do some short of action

events, in this program I had several situation to use this buttons, such as Save, Clear, Check Seat Availability,

Update, Delete and etc So those buttons are I added in my program.


11/74


11 | P a g e

Picture Box

Picture box is very good tool in vb.net. I have used Picture box for several forms in this student accommodation

system, simply drag and choose a picture from the local disk and according to our requirement we can make the

picture size easily by using this picture box tool


12/74


12 | P a g e

Criteria (P 15.1.2)

Develop the system using simple forms for the give scenario using interacting objects

Visual Basic forms are windows. It's an important piece of data because it ties the concept of a form in with

everything we already know about Windows applications.

Here's a simple Visual Basic form. It looks just like any other form that we use in Windows applications. The

header area has a caption, the control menu, and the minimize/maximize/close buttons. The large area of the

form is called the client area.

In Visual Basic, the basic building block of an application is a form, which is simply a window. The VB IDE can

insert forms into your project, and then you can resize the forms as well as change other properties of the form.

So after creating these forms we can add objects which we have in VB on top of that. Such as Textbox, Labels,

Combo boxes and etc

In this program me I have used more than 10 windows forms to develop the student accommodation system

Forms

From 1

Form 1 this name Login form.. in the student accommodation system. After entering the user id and Password

the user will able to logon to the system, by Entering the Wrong use rid and password the user will get and Error

Notification within the message Box

additional services and deletion modification also can be done in this form

Student Registrtion form

In this form Students can Enter They information before the Accommodation Registration


17/74


17 | P a g e

Accommodation payment form

This is accommodation payment form, the main reason I have designed to the accommodation system student

can provide the payment information also we need some proof and backups. So that I have design the payment

forms. Where we can enter the Given Student Id and the Date of Payment and

Reference No... This we need to provide to the student ID for each and every payment Transaction Function we

can delete the payment wrong payment we can edit, search also ca be done

This is Student Complain form., the usage of this form in

when student having any kind of complains about the

accommondation servicies , suggestion so they enter all the

information with the student Id Name , and they have toprivide valid information to procedue the Inuries

Criteria (P15.21.1) and criteria (P15.2.2)

Employ the different modeling techniques.

What is UML?

The Unified Modeling Language (UML) is a standard language for specifying, visualizing, constructing, and

documenting the artifacts of software systems, as well as for business modeling and other non-software systems.

The UML represents a collection of best engineering practices that have proven successful in the modeling of

large and complex systems.1 The UML is a very important part of developing object oriented software and the

software development process. The UML uses mostly graphical notations to express the design of software

projects. Using the UML helps project teams communicate, explore potential designs, and validate the

architectural design of the software.

Goals of UML

The primary goals in the design of the UML were:

Provide users with a ready-to-use, expressive visual modeling language so they can develop and

exchange meaningful models.

Provide extensibility and specialization mechanisms to extend the core concepts.

Be independent of particular programming languages and development processes.

Provide a formal basis for understanding the modeling language.

Encourage the growth of the OO tools market. Support higher-level development concepts such as collaborations, frameworks, patterns and

Components


24/74


24 | P a g e

UML Diagram Types

Each UML diagram is designed to let developers and customers view a software system from a different

perspective and in varying degrees of abstraction. UML diagrams commonly created in visual modeling tools

include

Use Case Diagram displays the relationship among actors and use cases.

1. A set of use cases and actors and their relationships.

2. Important for organizing and modeling system behaviors.

3. Crucial for requirements management and communication with end users using their own domain

terminology.

4. Uses very few symbols, all software independent

Class Diagram models class structure and contents using design elements such as classes, packages and objects.

It also displays relationships such as containment, inheritance, associations and others.

1. A set of classes, interfaces, collaborations, and relationships

2. Reflects the static design of a system.

3. Can be confusing if used to explain system dynamics; use less abstract Object Diagrams instead.

Interaction Diagrams

Sequence Diagramdisplays the time sequence of the objects participating in the interaction. This consists of the

vertical dimension (time) and horizontal dimension (different objects)

Collaboration Diagram displays an interaction organized around the objects and their links to one another.

Numbers are used to show the sequence of messages.

Composed of objects and messages dispatched between them.

1. Shows a dynamic view of the system.2. Sequence Diagram exposes time ordering of messages.

3. Collaboration Diagram exposes structural organization of messages.

4. In some tools (i.e. Rational Rose), these diagrams can be interchanged from the same underlying

information.


25/74


25 | P a g e

State Diagram displays the sequences of states that an object of an interaction goes through during its life in

response to received stimuli, together with its responses and actions.

1. Represents a state machine, composed of states and transitions.

2. Addresses the dynamic view of the system.

3. Useful for reactive behaviors.

4. Important for modeling interfaces, classes, or collaborations.

Activity Diagram displays a special state diagram where most of the states are action states and most of thetransitions are triggered by completion of the actions in the source states. This diagram focuses on flows driven

by internal processing

1. Addresses a dynamic view of the system.

2. Important for modeling system functions.3. Emphasizes the flow of objects and synchronization of the flow in support of parallel processing.

4. An extension of the old "flow chart" diagram combined with Petri nets.

Physical Diagrams

Component Diagram displays the high level packaged structure of the code itself. Dependencies among

components are shown, including source code components, binary code components, and executable

components. Some components exist at compile time, at link time, at run times well as at more than one time.1

1. Shows organization and dependencies among a set of components.

2. Components are composed of one or more classes or interfaces.

3. A static view of the system implementation.

4.

Deployment Diagramdisplays the configuration of run-time processing elements and the software components,processes, and objects that live on them. Software component instances represent run-time manifestations of

code units

1. Shows the configuration of run-time processing nodes in the system.

2. Nodes contain one or more components.

3. Address a static deployment view of the system.

Criteria (P15.3.2)

Use appropriate event handling for the Forms (EG: Database Connectivity)

Event Handling

To create an event handler in Visual Basic

1. Right-click the form and choose View Code.

2. From the Class Name drop-down box, select the control that you want to add a specific event handler to.

3. From the Method Name drop-down box, select the event for which you want to add a specific handler.

4. The Code Editor inserts the appropriate event handler and positions the insertion point within the

method. In the example below, it is theClickevent for theButtoncontrol.

5. ' Visual Basic

6. Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles

Button1.Click

' Add event handler code here.

End Sub

7. Add the appropriate code to the event handler.

Button Click Event for Clear the Data

PrivateSub btnclear_Click(ByVal sender As System.Object, ByVal e AsSystem.EventArgs) Handles btnclear.Click

'Creating sub class for Clear Buttonclear()

EndSub

Sub clear()

' will clear the Datas form the given lable ids

txtid.Clear()txtname.Clear()txtaddress.Clear()txtcity.Clear()txtstate.Clear()txtzip.Clear()txtemail.Clear()txtcontact.Clear()

EndSub

As you can see, there are basically two new things added:

1. The event subroutine arguments sender and e

2. The Handles clause

3. The Handles clause allows the same subroutine to be used for all kinds of event calls. Suppose, for

example, that you wanted a click in a Textbox and a Button to be processed by exactly the same code. No

problem ...

System Testing

System testing is the stage of implementation, which is aimed at ensuring that the system works accurately and

efficiently before live operation commences. Testing is the process of executing the program with the intent offinding errors and missing operations and also a complete verification to determine whether the objectives are

met and the user requirements are satisfied. The ultimate aim is quality assurance. Tests are carried out and the

results are compared with the expected document. In the case of erroneous results, debugging is done. Using

detailed testing strategies a test plan is carried out on each module.

Unit Testing

The software units in a system are modules and routines that are assembled and integrated to perform a specific

function. Unit testing focuses first on modules, independently of one another, to locate errors. This enables, to

detect errors in coding and logic that are contained within each module.

This testing includes entering data and ascertaining if the value matches to the type and size supported by java.

The various controls are tested to ensure that each performs its action as required.

Integration Testing

Data can be lost across any interface, one module can have an adverse effect on another, sub functions when

combined, may not produce the desired major functions. Integration testing is a systematic testing to discover

errors associated within the interface. The objective is to take unit tested modules and build a program structure.

All the modules are combined and tested as a whole. Here the Server module and Client module options areintegrated and tested. This testing provides the assurance that the application is well integrated functional unit

with smooth transition of data.

User Acceptance Testing

User acceptance of a system is the key factor for the success of any system. The system under consideration is

tested for user acceptance by constantly keeping in touch with the system users at time of developing and

making changes whenever required.

Future enhancement

1. inbuilt Backup and Recovery system

2. Access in online network

3. Email Facility for the Students to Notify the Information to Admin through the Accommodation system

4. 24/7 Live support should be enabled.

5. This project does not create monthly, yearly Reports.6. After removing these and other minor limitations I hope this project will very efficient and effective.

Conclusion

The project titled as "Student Accommodation System been designed with much care, with the intention easier

and the more complexity involved is presented in a simple and lucid style.

The project developed using VS and inbuilt SQL is based on the requirement specification of the user and the

analysis of the existing system, with flexibility for future enhancement.

The expanded functionality of todays software requires an appropriate approach towards software

development. This Student accommodation system is designed for people who are seeking Accommodation in

studying citys.

The product has enormous repetition value as user will be in need of saving time for efficient management of his

computer resources. The volume of data and storage capacity is increasing exponentially.

The program is not only useful for educational institutions University Students , organizations

Identification of the drawbacks of the existing system leads to the designing of computerized system that will be

compatible to the existing system with the system which is more users friendly and more GUI oriented.

The System works in a similar fashion as that of an accommodation system, the various Department student

information is to be stored and retrieve any time when required.
