Types of Table Spaces in DB2

In DB2, there are several types of table spaces that serve different purposes. The main types of table spaces in DB2 are:

1. Regular Table Space: Regular table spaces are used to store normal user data in a DB2 database.
2. Large Table Space: Large table spaces are designed to store very large tables or tables with large rows in DB2.
3. Temporary Table Space: Temporary table spaces are used to store temporary data that is generated during query processing or sorting operations in DB2.
4. System Temporary Table Space: System temporary table spaces are used to store temporary system data in DB2.
5. Partitioned Table Space: Partitioned table spaces are used to horizontally partition data across multiple physical storage objects in DB2.
6. Universal Table Space: Universal table spaces are a type of table space introduced in newer versions of DB2 that allow for easier management and greater flexibility in storage allocation.

Each type of table space in DB2 has its own specific characteristics and use cases, and understanding the differences between them is important for efficient database management.
