Question

For which task would you use a database definition language (DBDL)?

A) Retrieving data from a database
B) Updating records in a database
C) Defining the structure of a database
D) Sorting and filtering data in a database

Answer 1

A database definition language (DBDL) is used for defining the structure of a database, which includes creating tables, defining fields, and setting up relationships between tables.

Step-by-step explanation:

You would use a database definition language (DBDL) for option C) Defining the structure of a database. DBDL is a part of SQL (Structured Query Language) that allows a user to specify not only a database schema but also the data types and constraints for the data to be held in the schema. Creating tables, defining fields and data types, and setting up relationships between tables are all tasks that would involve the use of DBDL. It's specifically meant for the creation and modification of the structure of a database, not for updating, retrieving, or sorting/filtering data which are handled by other components of SQL such as Data Manipulation Language (DML) and Data Control Language (DCL).
