Which process involves changing the attributes of a database object?

• A. CREATE
• B. ALTER
• C. DROP
• D. RETRIEVE

Answer: (B)

The process that involves changing the attributes of a database object is known as ALTER. When you use the ALTER command, you can modify various aspects of existing database objects—such as tables, views, or columns. For example, you can change the data type of a column, rename a table, add a new column, or drop an existing column. This command is fundamental for managing and maintaining databases, ensuring that the structure aligns with the evolving data requirements. In contrast, the CREATE command is used to create new database objects from scratch, which does not involve altering existing attributes. The DROP command is employed to completely remove an object from the database, rather than modifying its characteristics. RETRIEVE pertains to querying data from a database, which focuses on data retrieval rather than structural changes. Thus, ALTER is the correct choice for modifying an object's attributes.
