Drawbacks of the Existing System

The primary drawbacks in the existing system are listed below:

The process is time consuming and sometimes erroneous also leading to

invalid stock details.

Maintenance of record is not easy, because all process should maintained

manually

Less data security.

Updating the data is not quit simple.

Much delay in information searching and retrieving .

There is lot of human intervention that is needed in the manual process where

the error is common.

There is possibility of error occurrences when handled a data manually

2.2 NEED FOR PROPOSED SYSTEM

The proposed system is a GUI based application which takes care of the firm

management. The proposed system includes the process of maintaining the stock

information,

The drawback of the existing system provides the requirement for the

development of new system. Our proposed system solves this drawback and works

satisfactorily. The proposed system is good management information system. The

proposed system is based on computerizing the existing manual system.

6

2.3 OBJECTIVES OF PROPOSED SYSTEM

The proposed system has the following objectives that satisfy the user

willing.

Completely menu-driven & user-friendly.

. Reports are quickly available to the management.

Adding, selecting, updating, editing can be easily done.

It reduce cost and saves time

Providing more security than existing system

the entire sales with the information about customer name, date of sale, stock code, sale

price and quantity. By using this report the firm can know the sales level.

12

4. TESTING & IMPLEMENTATION

4.1 SYSTEM TESTING

All the modules of this system were successfully implemented and testing of the

project completed using test data as well as real data collected from the firm. All the

reports and the screens are tested for their validity and values in the data tables are

checked for their correctness and consistency. After successful testing of the system, it is

ready for implementation.

Types of testing

Unit testing

Integration testing

User Acceptance testing

White box testing

Black box testing

UNIT TESTING:

In this testing, the modules in the project are tested independently with each and

every forms associated with their functions and sub routines and then it gives the valid

accurate data. This concentrates or focuses on individual modules independently, to

locate for the errors. No errors found.

INTEGRATION TESTING:

The individual modules namely purchase module, sales module, stock module were

linked together, at last the entire forms got together. Initially low volume of data is given

to all the modules and the outcome is taken to consideration with the old one. Stock

module is affected when the transactions were made. The data retrieval from the table

was slightly changed due to the order of parameters in the subroutine. It was observed and

resolved. The candidate system has passed the test .

13

USER ACCEPTANCE TESTING

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

system is tested for user acceptance by constantly keeping touch with prospective system

and user at the time of developing and making changes whenever required. This is done

regarding to the following points.

Input Screen Design

Output Screen Design

Format of the report and other output

User accepted the system satisfactorily.

WHITE BOX TESTING:

In this test, all the logical decisions involved in the project is tested by giving the

true and false sides of data and all the loops are executed. When anywhere in the project ,

the data of the procedure call went beyond the limit, it was caught and produce the alert

signal to user.

BLACK BOX TESTING:

It is not an alternative to white box techniques. It attempts to find errors in the

following categories.

Incorrect or missing functions => No errors were detected.

Interface errors => a recordset error occurred as recordset was not closed while

navigating user interface screen and it was corrected.

Errors in data as structures => Validation check was placed where the system

required input from the user. So that the occurrence of error in data was avoided .

.

4.2 IMPLEMENTATION

14

Implementation is one of the most important tasks in project is the phase in which

one has to be cautions because all the efforts undertaken during the project will be very

interactive. Implementation is the most crucial stage in achieving successful system and

giving the users confidence that the new system is workable and effective. Each program

is tested individually at the time of development using the sample data and has verified

that these programs link together in the way specified in the program specification. The

computer system and its environment are tested to the satisfaction of the user.

5. CONCLUSION & SUGGESTIONS

5.1. CONCLUSION

The candidate system is carried out to overcome the problems that are

faced in the manual system. The objectives of the candidate system have been designed

successfully. The computerization of aquarium shop activities reduces work load of

administrator, maintainer or owner as well as more user friendly.

The salient features of this project are:

High speed of transaction.

Avoids data redundancy.

Provides speed data retrieval with accuracy

5.2. SUGGESTIONS

The scope for further enhancement in the project is by making this into

online, so that the management can know the activities of other branches if the shop has

branches in somewhere.
