What does it mean to create a 'view' in HANA?

• A. To store data physically in a new table
• B. To create a physical backup of the database
• C. To create a virtual table that presents data
• D. To delete unnecessary data from the database

Answer: (C)

Creating a 'view' in HANA means establishing a virtual table that presents data sourced from one or more underlying tables. This virtual table does not store the data itself; instead, it simply provides a way to access data through a defined query. Views allow users to simplify complex queries, encapsulate business logic, and present data in a specific way without altering the underlying data structures. For example, you might use a view to combine rows from various tables or filter results to present only necessary information to specific users or applications. The purpose of a view is to enhance data accessibility and organization while maintaining efficient storage and management of the original data. Therefore, the concept of creating views is a fundamental aspect of relational databases that facilitates better data handling and reporting capabilities.
