Next Chapter 14 DESIGNING OF SYSTEM
Purpose of designing of system is to state that how a system will meet the requirement identified during system analysis, often refer to this stage as logical design, in contrast to the process of developing program software, which is referred to as physical design. System analysts being the process by identifying reports, the requirement and output need by the system. Then the specific data on each are pinpointed. Usually, designers sketch the form or displays they expect from the system. This can also be done on a paper or on the computer display with the help of automated system tools available. The system design also describes the date to be input, calculated, or stored. Individual date items and calculation procedures are written in detail. The procedures tell how to process the data and produce the output. Designers are responsible for providing programmers with complete and clearly outlined software specification. As programming starts, designers are able to answer questions, clarify fuzzy areas, and handle problems that confront the programmers when using the design specifications. As the software is to be designed in VISUAL BASIC 6.0 and back-end SQL SERVER 2000, the concept of database is must for quantity designing. It will be designed of the database, designing of forms, designing of reports.
Unlikely the existing system, separate table have been created for specific details. In order to make the response time negligible; all the tables have been created in the memory file system (MFS). Moreover, indexes have been created on the tables in which the number of records is very large. Therefore, in the proposed system, search for a value has been made direct. This is contrast to the sequential search being done in the existing system have been taken care of in the system.
