| BGS+(Batch Gamme system plused) is a system that strengthens the BGS running on the host computer. The implementing model of this system is B/S and the developing platform is J2EE . This paper detailedly introduces the development of this system and the key technology of this system.The pager has two parts. The first part is the theory that this system based on: B/S model, UML ,XML ,J2EE and so on. This part introduces their characteristic of technology. The second part introduces development of this system: the methodology that developers how to work , analyzing requirement of users, designing for system, realizing system and so on.The database of BGS is a hiberarchyed database.In the phase of designing author analysed the system using object-oriented method and constructed a model of the system by UML. Author constructed many tables of database using a method that a class created a table. The system has created a database and has realized the process that transformed a hiberarchyed model to a relationed model. Author divided the system into 10 dealing entities by the object-oriented model in the phase of programming. Every entity responses the operations for a object. The entity is constituted by Model-View-Control. It separated the function of displaying data and the function logic of application and the function of dealing database.BGS+ has four function modules: module of maintenance gamme data, module of printing gamm report-forms, module of transmitting data and security of system module. BGS+ uses unified interface and unified flow to realized function of dealing data with formatting information. So it has reduced the complexity of the system. For example, BGS+ uses XML to describe format of report forms. Printing program parses the XML files and creates the report forms in PDF format. In transmitting data module BGS+ describes the relation of table and data and designs a builder creation SQL. Control program can use its interface to import data into database. |
