Brief introduction of basic principles of database management System selection

Sam technology to the database management system selection should follow the following basic principles:
1. Stable and reliable
The stable and reliable database can guarantee the operation of the business system all the year round, and will not suffer the loss due to the database problems, the database should have the functions of disaster recovery, system error recovery, human operation error recovery and so on, while minimizing the planned maintenance time of the database.
2. Scalability
With the expansion of future business, the processing power of the system should be gradually increased to meet the needs of business processing. Database should have good scalability and flexible configuration, whether it is the host system memory or hard disk expansion also clustered system expansion, can be used by the database, thereby improving the system's processing power.
3. Security:
Database security refers to the protection of the database to prevent illegal use caused by data leakage or destruction. The data security control mainly through the user identification and the authentication, the access control, the view, the audit, the data encryption and so on mechanism completes.
4, a wealth of development tools
At present, the popular database management system generally follows the unified interface standard, so most of the development tools can be developed for the application of many kinds of databases.
5, high-quality service
At present, the quality of the database products in the gap gradually narrowed, and the user to select a product is an important factor in the manufacturer's technical services.
