Design and development of an information management system

Abstract

This thesis presents a compete analysis. design and development of an information management system [ 1MB ]. The existing manual information system is analyzed, different solutions with performance and costing are presented and a gantt chart is prepared for the recommended solution. A computerized information management system is designed. Design of the computerized I M S involves design of conceptual model, logical model, output, input, database, menu structure. process, program, package. system operation and maintenance. and system security and control. All these design works are presented in chapter 4 . Different queries are formulated in the form of menu structures so that any query can be resolved after entering appropriate data sought by the system. A database is designed to store data. Catalogs of various attributes, database files, program files etc are accommodated in database dictionary. As informat~ion is a vital factor in any organization. the system is designed with two levels of password-control. In Bangladesh, there a is random change of government policies regarding some attributes; so the system is made independent of government policies. That is, if the system manager ehter changed data in related data file[s] ," the system will serve accurately after the change of government policies affecting some attributes. Finally the designed system is developed using the programming language of dBASE III plus. Various development works are presented in chapter 5 The performance and specifications of the developod system is then compared with that of the designed system.
