Establish an efficient dynamic Website production It is very important to select a good database. At present, the commercial database management system takes relational database as the leading product, and the technology is relatively mature. Although the object-oriented database management system is technologically advanced, it is easy to develop and maintain. But there is no mature product yet. Since the relational data model was proposed in the 1970s, it has been rapidly adopted by commercial database systems due to its outstanding advantages. According to statistics, nearly 90% of the newly developed DBMS systems are based on relational data models, and many commercial relational database management systems with excellent performance have emerged. For example, small database systems such as Foxpro and Aeeess, and large database systems such as DBZ, Oraele, and SQL Server. Next, we will compare and analyze the performance of common database management systems. 1. Database system with traditional single table structure For database systems such as dBase, FoxBase, FoxPro, and Access, databases are files with the extension. dh, and operations on databases are operations on these files. At present, most development tools support these database systems. These system users are small in scale and generally limited to desktop applications. The following is a brief description of the ACCESS system. A special feature of Access is that all tables in a database are placed in a file (. mdb file). Access can facilitate the management of this file. Of course, the Access database can also be managed through the foreground program. Access database is supported by popular development tools at present. The application of Access database system is also limited to small occasions and cannot support large applications. 2 . MySQL database management system MySQL is a fully networked cross platform relational database system and a distributed database management system with client server architecture. It has the advantages of powerful function, simple use, convenient management, fast running speed, strong security and reliability. Users can use many languages to write programs to access MysQL database. In addition, MySQL is free on Linux, UNIX and other operating systems; The WindowS operating system can also use its client programs and client libraries for free. In addition to supporting standard ANsl SQL statements, MySQL also supports multi-threaded running on the uMX system, which can achieve good performance. For users who do not use UMx, it can run in system service mode on Windows NT/2000 system, or run in normal process mode on Windows 95/98 system. MySQL is ideal for small and medium-sized applications, so it is considered the best product for building database driven dynamic websites. 3 . Oracle Database Management System When it comes to enterprise level databases, many people think of Oracle first. Oracle was founded in 1977, initially as a company specializing in database development. Oracle has always been a leader in the database field. In 1984, it first transferred the relational database to the desktop computer. Then, Oracle took the lead in introducing new concepts such as distributed database, client and server structure. Oracle 6 pioneered the row locking mode and the support of symmetric multiprocessing computers. Since Oracle 8, object technology has been added to become a relational object database system. At present, Oracle products cover dozens of models such as large, medium and small computers. Oracle database has become one of the most widely used relational data systems in the world. 4 . Microsoft SQL Server Microsoft SQL Server is a medium-sized relational database management system developed by Microsoft itself. It has the characteristics of client/server architecture, graphical user interface, rich programming interfaces, etc. To sum up, as the most popular, practical and easy-to-use database system in the market, SQL Server is widely used in dynamic website systems. It is applicable to small and medium-sized commercial websites that have been running for a period of time and have a certain foundation in terms of traffic and popularity. But. It is also worth noting that SQL Server can only run on the Windows operating system. The reliability, security and scalability of Windows 9x/NT/2000 are very limited. It is not as tested as UNIX, especially when dealing with critical businesses with large amounts of data. Therefore, considering the system openness, scalability and feasibility, security, client support, application mode and system performance, Oracle should be the first choice. If the website is just created and the scale and traffic are still in the initial stage, users can choose some small database systems that are easy to use, such as Access, FoxPro, etc. If you do not need the support of stored procedures and the database access is not too large, you can use MySQL, a lightweight database under Linux. It can provide the best performance, good manageability and security. Finally, it should be noted that the main feature of database technology from its birth to today is to support increasingly diverse application types. Object oriented database technology is an inevitable trend. However, database systems are created for specific applications, and database products are purchased for the purpose of applications. You must not drift with the tide for the sake of technology. Therefore, as long as it meets the actual needs of the enterprise website, it is the best product, and enough is the purpose. Never buy things that are not needed temporarily. Because computer technology is developing rapidly, it is impossible to reach the goal in one step. Of course, the system must be an extensible and scalable open product. In this way, it can be upgraded as long as necessary.
