A data control language (DCL) is a syntax similar to a computer programming language used to control access to data stored in a database (Authorization). In particular, it is a component of Structured Query Language (SQL). Examples of DCL commands include: GRANT to allow specified users to perform specified tasks.

In the context of SQL, data definition or data description language (DDL) is a syntax similar to a computer programming language for defining data structures, especially database schemas. DDL statements create and modify database objects such as tables, indexes, and users.

C is the answer to this question. C language only accepts two data types namely primary data types and derived data types. The primary data types will come in the form of integer, character, void, and floating point. Derived data types come in the form of an array of union, structure, and the last is the pointer.

Python is also better for data manipulation and repeated tasks. The future scope of Python is bright as it also helps in the analysis of a large amount of data through its high-performance libraries and tools. One of the most popular Python libraries for the data visualization is Matplotlib.

The Data Analysis expressions (DAX) language provides a specialized syntax for querying Analysis Services tabular model. DAX is not a programming language. DAX is primarily a formula language and is also a query language.

One of the important differences between DDL and DML is that Data Definition Language (DDL) defines the schema of the Database whereas the Data Manipulation Language (DML) is used to modify the schema of the Database. DDL commands are CREATE, ALTER, DROP, TRUNCATE, etc.
