What is the purpose of defining schemas in SAP HANA?

Defining schemas in SAP HANA serves as a foundational aspect of organizing and managing database objects efficiently. A schema acts like a container that groups related database objects such as tables, views, and stored procedures. This structured approach helps maintain clarity within the database environment, making it easier for database administrators and developers to locate, manage, and utilize these objects. By providing a clear organizational framework, schemas also facilitate better maintenance and understanding of data relationships.

While restricting access to specific users and groups is an important feature of schemas, it is more of a byproduct of their structured organization rather than their primary purpose. Similarly, while optimized query performance can be a result of good schema design, this is not the core reason for defining schemas. Backup copies of the database relate to data recovery and protection rather than the organizational purpose of schemas themselves. Therefore, the main objective of defining schemas truly lies in providing that structured way of organizing database objects within SAP HANA.
