Which SQL command allows a DBA to create a view named 'RecentOrders' displaying recent orders based on the order date?

• A. CREATE VIEW RecentOrders AS ...
• B. INSERT INTO RecentOrders AS ...
• C. DROP VIEW RecentOrders AS ...
• D. UPDATE VIEW RecentOrders AS ...

Answer: (A)

The command that allows a Database Administrator (DBA) to create a view is the one that begins with "CREATE VIEW". When a view is created, it acts as a virtual table that can represent the results of a query. By using "CREATE VIEW RecentOrders AS ...", the DBA defines the structure of this view along with the accompanying SELECT statement that pulls data for recent orders based on the order date. This allows users to easily query and utilize this data without needing to restructure the underlying tables each time. This command is foundational in SQL for organizing complex queries into simpler, reusable components, making data management more efficient and enhancing access to specific information without directly interacting with the base tables. The other options provided are not suitable for creating a view; they serve different functions, such as inserting, dropping, or updating existing views but do not initiate the creation process.
