Oracle Database Administration from Zero to Hero - Using Deferred Segment Creation

This lecture covers deferred segment creation in Oracle databases, a feature introduced in Oracle 11G to optimize storage by delaying segment allocation until data is inserted. It explains how this feature saves disk space and reduces installation time. The lecture also discusses controlling this feature through initialization parameters and the CREATE TABLE statement. Additionally, it covers materializing database segments using the DBMS_SPACE_ADMIN procedure, allowing segments to be created without data insertion. The lecture concludes with a summary of key points.
