8 Commonly Used Database Management Systems

Database Management System (Database Management System) is a large-scale software that manipulates and manages databases. It is used to establish, use and maintain databases, referred to as DBMS. It is an indispensable data management software for enterprises to manage and maintain data.

   Introduction to 8 commonly used database management systems:

  1.Oracle:

  

  Oracle is the abbreviation of Oracle Database, or Oracle RDBMS. It is a relational database management system of Oracle Corporation. It is the first product in the database domain. It can be said that the Oracle database system is a popular relational database management system in the world. The system has good portability, convenient use, and strong functions, and is suitable for various large, medium, small and microcomputer environments. It is a high-efficiency, reliable and high-throughput database solution.

  

  2.Sybase:

  

   Sybase is a typical large-scale relational database system in a client/server environment on UNIX or WindowsNT platforms. Sybase provides a set of application programming interfaces and libraries, which can be integrated with non-Sybase data sources and servers, allowing data to be copied between multiple databases, and is suitable for creating multi-tier applications. The system has complete triggers, stored procedures, rules and integrity definitions, supports optimized queries, and has better data security.

  

  3.Informix:

  

   Informix is a relational database management system produced by IBM. As an integrated solution, it is positioned as the flagship data service system of IBM Online Transaction Processing (OLTP). IBM has long-term plans for Informix and DB2, and the two database products draw on each other's technical advantages.

  

  4.MicrosoftSQLServer:

  

   Microsoft SQL Server is a relational database management system launched by Microsoft. It has the advantages of easy to use, good scalability and high degree of integration with related software. It is a comprehensive database platform that uses integrated business intelligence (BI) tools to provide enterprise data management. The Microsoft SQL Server database engine provides more secure and reliable storage functions for relational data and structured data, allowing you to build and manage highly available and high-performance data applications for business.

  

  5. Microsoft Access:

  

Microsoft Office Access is a combination of the two features of Microsoft JetData base Engine and graphical user interface. The relational database management system released by Microsoft is one of the system programs of Microsoft Office. It is sold separately in the office version including the professional version and later. .

  

  6. Visual FoxPro:

  

   Visual FoxPro is abbreviated as VFP. It is a database development software launched by Microsoft, which is derived from the database product FoxBase launched by Fox Software in the United States. It runs on DOS and is compatible with the xBase series. Using FoxPro to develop a database is simple and convenient. The current new version is Visual FoxPro9.0, and the classic version of Visual FoxPro6.0 is still used in school teaching and education departments. In desktop database applications, the processing speed is fast, and it is a powerful assistant in daily work.

  

  7.DB2:

  

  DB2 is a series of relational database management systems produced by IBM, which serve on different operating system platforms. Although DB2 products are UNIX-based systems and personal computer operating systems, in terms of UNIX-based systems and Microsoft Access under Windows systems, DB2 pursues ORACLE's database products.

  

   8. MySQL:

  

   MySQL is a popular relational database management system, especially in WEB applications, MySQL is a good relational database management system. Developed by the Swedish company MySQLAB, it is currently owned by Oracle. The SQL language used by MySQL is a commonly used standardized language for accessing databases. The software adopts a dual authorization policy and is divided into a community version and a commercial version. Due to its small size, fast speed, and low total cost of ownership, especially the characteristics of open source, the development of small and medium-sized websites chooses MySQL as the website database. Due to the excellent performance of its community version, it can be combined with PHP, Linux and Apache to form a good development environment. After years of web technology development, one of the web server solutions widely used in the industry is called LAMP.

  

   The database management system based on the relational model has been perfected day by day, and has been widely used in various industries as commercial software. Its application in the distributed multi-user environment of each server structure makes the application of the database system progress and expand. With the advancement of new data models and implementation technologies for data management, it can be expected that the performance of DBMS software will be updated and improved, and the application domain will also be broadened.
