Tablespaces serve several crucial purposes in Oracle databases, all contributing to better organization, performance, and manageability. Here's a breakdown of the key reasons for using them:
Logical Data Organization: Tablespaces provide a logical layer of abstraction between the physical datafiles and the database objects (tables, indexes, etc.). This allows you to organize data logically, grouping related objects together. For example, you might have a tablespace for application data, another for user data, and another for indexes. This logical separation simplifies management and makes it easier to understand the structure of your data.
