What is the function of a 'Schema' in SAP HANA?

• A. It specifies the hardware requirements for the database
• B. It manages user permissions for database operations
• C. It defines the structure of the database, including tables, views, and data relationships
• D. It acts as a log for all transactions performed

Answer: (C)

The function of a 'Schema' in SAP HANA is to define the structure of the database, including tables, views, and data relationships. A schema serves as a logical container that organizes database objects. It plays a pivotal role in how the data is structured and accessed, allowing for effective categorization of related data entities. Within a schema, you can create and manage various database objects like tables, which store actual data; views, which present data in a specific format or structure without duplicating data; and relationships, which define how different data entities are connected. This structural organization is essential for efficient data management and retrieval. In SAP HANA, having well-defined schemas helps ensure data integrity, improves query performance, and provides a clear organization that facilitates both development and database administration tasks. This capability to define and organize the composition of database elements is central to the overall functionality of a database system.
