Precisions

The organization of data has a strong impact on the search performance in a DBMS. The rules for structuring data collections make it possible to optimize these points. DBMS engines also have performance indicators that facilitate optimization procedures. Less time and processing to access data means less energy consumption and less need to oversize the servers that host these engines.

Use Case

DBMS monitoring track index efficiency data reorganization
