What is the function of table spaces in DB2?

In DB2, a table space is a logical container used to store table and index data. The main functions of a table space include the following:

1. Provide data storage: Tablespace is where tables and index data are stored in the database, and tables and indexes can be allocated to different tablespaces as needed to better manage data storage.
2. Control data growth: By setting the size and growth method of the table space, you can effectively manage data growth and prevent situations where there is insufficient data space.
3. Improving performance: Using table spaces effectively can enhance the performance of the database, such as placing frequently accessed tables and indexes in high-performance table spaces.
4. Manage data: By managing table spaces, it is possible to perform operations like backup, restore, and move data, making it easier to manage and maintain data.

In conclusion, table space plays a crucial role in DB2, playing a vital role in the performance and data management of the database.
