Contract Information Management System Design And Implementation

Along with the application of computer technology in information management, the improvement of contract information management becomes imperative. The contract management system that this article develops is the typical management information system (MIS),has used mainly three structures of B/S/S (BROWER/Application server/Database server), and mainly includes three aspects: the establishment and the maintenance of the backstage database, front end' s application procedure as well as the development of the intermediate application server level. Requiring to establish a good database in which you may find the uniformity, the integrity and the security of the data; the application procedure needs to have the characteristic of complete function, easy in using and so on;and the intermediate application server level should have the performance which can nimbly change along with the enterprise logic change. The using of the engineering design method and the thought of facing the object has provided the instruction to the success and the fast development of this software.The contract management system is a contract, according to the user' s request, realizing several functions such as contract information management, financial control, customer management as well as product management and so on. Through the user' s input of contract information, customer information, equipment information, etc., the system independently produces the corresponding statistical data and each kind of statistical report form for the user to inquire and to print; moreover the user also may carry on the regular renewal and the deletion to these basic information, the system makes every effort to help the user to manage the tedious data conveniently and quickly.The front end and the intermediate level of the system use the EOS development kit of Primeton Corporation, and every kind of object-oriented development kit it provides. The backstage server end uses Oracle 8i, supports the great data quantity, the multiuser' s high performance using on business processing, the secure and complete control, as well as the merits of probability, compatibility, connectability and so on, makes every effort to establish a reliable and safe database.In the entire research and development of the system, from the demand analyzes ta the system realization, strictly according to the engineering method, analyze carefully and implement earnestly, has conducted the analysis research of the jurisdiction controls of three structures of B/S/S, and the data transformation in the new and old systems, proposed the solution and finally solved the problem of jurisdiction control and the document passing-on in the system.
