realistic simulation of the data model. Relational database as they use more data model, which might lead to a massive storage space and wasting a lot of increase, and cause the system to respond to the declining performance. Furthermore, the data in reality, there are many types of relational database is not well addressed. Static applications such as report generation, and the design of the relational database management system after no response and efficient business processing for the optimization process. The result is often some relational database products, in the GUI and Web Services processing, not achieved the desired results. Unless additional hardware investment, but it does not resolve the fundamental problem. Relations with the twodimensional database table data model can deal with the majority of business application of a typical multi dimensional data, but the results are often the establishment and use of a large amount of data forms, it is difficult to establish a simulation of realworld data model. And the need for data output statements when they, in turn, would have dispersed the large number of twodimensional data tables. Reuse indexing technology linking the table in order to find all the necessary data, this, in turn, is bound to affect the use of the response speed. Database various databases is currently the most important and the most popular database. Relational database system to support the relational model of database systems, relationships between data model structure, relations operation and integrity constraint set is posed of three parts. Office Access2020 is the Chinese version of one of the ponents. Access2020 to the previous version, the Access2020 is not only a more friendly interface, but their functions have also been strengthened, especially work function was improved, Inter Access2020 so that it more closely connected. Access2020 is a small and mediumsized database management system, easy to use, powerful, and other databases have a good interface. Access2020 through powerful tool, users can facilitate the use and management of databases, such as the creation and editing of data tables, design and the use of various tools inquiries query operation, design and the use of windows, production and printing statements, the design and use of Acer, the design and use of such Web pages. May also be used in Visual (Visual for Application)Advanced Application Development procedures. Access2020 is a plete database application development tool, the user can design, modify, View a record of the basic data table。 in the table data for various screen and query operation。 design and use of Window to。
