The correct choice is related to the language used for defining and modifying database structures. DDL stands for Data Definition Language. This set of commands is crucial for specifying database schemas, creating and altering tables, defining constraints, and managing the structure of the data within a database.

Data Definition Language includes commands such as CREATE, ALTER, and DROP, which are essential for establishing the structure of databases that support data storage and access. Knowing DDL is fundamental for database administrators and developers because it allows them to define how data is organized, the types of data that can be stored, and the relationships among different entities in the database.

The other options, while related to data and databases, do not accurately represent what DDL stands for. Each has its own context that does not align with the standard definition of DDL in the realm of databases. For example, "Data Declaration Language" sounds related but does not exist in formal database terminology. Similarly, "Distributed Data Language" and "Data Description Language" do not have definitions associated with standard database operations. Understanding the specific terminology and its correct applications is essential for effective database management and design.
