The Analysis And Designment Of Relational-Database For Leechdom Manage System Based On Object-Oriented

The analysis and design of administration system for leechdom management is based on the needs of enterprise of managing leechdom. The design for Relational database studied in this paper is an important part of the Vico administration system of for leechdom management in Version 2, which will be a new system based on Version 1. In this work, an new Relational database is established. The work mainly includes the following conclusions:1. Analyze the needs of enterprise, and describe the reason and the theory of Distributed N-tier architecture ; Expatiate the technical idea of designing a relational database using the object-oriented method, and introduce the means of mapping between the object models and the relational database;2. Describe the key technologies and ways to modeling database with UML; In the analysis and design of database for purchase, using UML to analyze and model, achieve the database model chart, and establish the database.3. Describe the methods and technologies for optimizing the database performance, based on the structure design of database.The OO(Object-Oriented) and the relational database designing are combined in this database design for Vico Leechdom Management System, so the whole development and design environment of the system development including the database design become uniform. It is so important to establish the database for administration systems that realization of the software modeling.
