1. BACKGROUND

Vaal College (VC) is a private institution that has been existence for decades. It is oneof the few colleges that has managed to remain positive despite the current economichard times that many institutions face. It provides higher learning education tostudents.

2. MISSION & VISION

VC aims to be the first African world class institution that provides distinctive learningenvironment to its students with the best state of the art technology. It also aims tomerge with other private institutions to provide the best learning experience. This willsubstantially contribute to the growth of the economy and in turn reduce the highlevels of employment.

3. OBJECTIVESVC s main objective is to provide a world class learning environment to itsstudents through the implementation of database system called IntegratedStudent Database System.

4. CURRENT SYSTEM INFRASTRUCTURE

VC uses traditional file processing system and relies heavily on paper work to conductits day to day operations. The following hardware and software technology arecurrently in use:

Hardware: Intel Pentium 4 1.6GHZ (CPU) 40 GB IDE Hard drives CD-RW Drive VGA Monitor 640 x 800 InkJet Printer

Software: Windows 2000 SP 2 Microsoft Office 2003

5. SYSTEM REQUIREMENTS

Server: Intel Pentium 4 3GHZ (CPU) MS 2003 Server 500 GB IDE Hard drives DVD-RW

SVGA Monitor 780 x 1024 Laser Printer Oracle 10g Developer SQL 10g Database

Client: Intel Pentium 2.5GHZ Windows XP SP 2 80 GB Hard drives DVD-RW SGVA 780 x 1024 Ms Office 2007

6. PIECES FRAMEWORK

Pieces is an acronym for Performance, Information, Economics, Control,Efficiency and Service, which is a framework for identifying and classifying

business or system problems and taking corrective action to improve the quality of services to business stakeholders.

1. Performance :

(a) Throughput the amount of work VC staff members perform duringregistration is exhaustive (tiring) since staff members rely on manual paperwork to register students each year.

(b) Response Times students are not notified in time about the notificationstatus.

2. Information :

(a) Outputs:

i. Students do not have readily available access to information abouttheir status of application.

ii. There is too much information information overload that isunnecessary.

iii. Information is not in useful format and that makes it difficult for

students and other users to interpret it.

iv. Information is difficult to produce to reflect current VC availablecourses.

(b) Inputs:

i. Due to excessive use of paper work, data sometimes is not capturedor it is not captured in time.


5/15

ii. Data captured contains errors that management cannot base their

decision-making on it.

iii. Data captured contains redundancy and that creates a lot of confusion between information users.

iv. The accuracy of data captured cannot be verified - illegal data.

(c) Stored data:

i. Data is stored in multiple files/databases causing data redundancy consuming unnecessary storage space.

ii. Same data have different data values in different files. This causespoor data integration hence VC cannot trace students who haveoutstanding fees.

iii. Data is vulnerable to security and vandalism that would cost VC lossof valuable information.

iv. It becomes difficult to access stored data since data is not wellorganised.

3. Economics:

(a) Costs:

i. Costs are incurred but the source of the costs cannot be traced.

ii. Costs are too high and unjustifiable.

(b) Profits:

i. New markets can be explored.

ii. Students registration process can be improved.

4. Control and Security:

(a) Too little Security:

i. Unauthorised people may fraudulently access data and use it commitvarious crimes.

ii. Data is not secured and there it is violated

(b) Too much control or security

i. Data is too secured and slows the system.

ii. Excessive controls cause inconvenience for system users.


6/15

5. Efficiency

(a) People, machines or computers

(i) Students records are redundantly input.

(ii) Information is redundantly generated.

(b) Staff members waste a lot of effort to access data.

6. Service

(a) Since VC currently uses traditional file system, it produces:

(i) Unreliable results

(ii) Inaccurate reports

(iii) Inconsistent results

(b) The system is not user friendly and requires a lot of effort to learn it.

7. PURPOSE OF THE SYSTEM

(Integrated Student Database System)

Integrated Student Database System ( ISDS) is a database system to be developed by C&L IT Solutions to address the challenges that Vaal College faces as indicated in thePieces Framework.

(a) It will speed up the registration process by automating data entry asopposed to manual (paper work) there by reducing the cost of stationery.

(b) It will capture students application details and store them in a securedcentralised database.

(c) The system will generate reliable results and parameter driven reports uponwhich management can rely on decision-making.

(d) The system will alert users about the availability of courses at hand

(e) Students will be able to access their records in the database upon providingtheir credentials. This increases the level of database security.

(f) VC Lecturers will be able to track students progress in time.

8. BUSINESS RULES FOR VAAL COLLEGE

To ensure that Vaal College meets its objectives, the Cuthbert IT Solutions team willenforce business standards in its implementation of the new system. These rulesensure that a certain criterion is met before a certain business event is done.


7/15

The system will verify if the student has provided enough and valid

information upon registration. The system will generate a student number and must use that number

to register for a course. A student can register for more than course Once verified, the student information will be stored in the student

master file for future reference and will be notified of the applicationstatus instantly.

A student must attend subjects in order to write a test A Lecturer must be qualified in order to teach allocated subjects One subject cannot be taught by many lecturers at the same time.
