Research and Implementation of Lightweight Database Management Information System base on GWT Framework
Résumé
With the prevalence of networks and a lot of lightweight-database are used in many small and medium enterprises, the management information systems (MIS) need to build a lot of queries to meet the users’ requirements, which leads to the duplication of development. When the users’ query-needs are not fixed or will change often, (a fixed user interface only meets a fixed need), these systems obviously can not meet the needs of users. Because the End Users cannot interact with the database directly, system developers cannot demand End Users to learn the knowledge and technique of the database.
This thesis studied and implemented a simple-query user interface for an inquiry supported environment. As long as the user knows the name of the database table attributes and the meaning contained, not need to know the knowledge of database query language, they can create the specific-need queries through the MIS. Company SAP provided products such as Business Object for large enterprises. (BO is a system which can make the reports by inquiring large database). This paper focused on the research of lightweight database MIS which can do the agile query operation.
