The most common and efficient way to retrieve information from the data dictionary (also known as the system catalog) of a relational database is to use SQL SELECT statements. The data dictionary is a set of tables and views that contains metadata about the database, such as the names and data types of tables, columns, indexes, constraints, and other database objects. By querying these tables and views with SELECT statements, you can obtain information about the structure and properties of the database and its objects. Cobol application programs or triggers are not typically used for this purpose, and a CREATE DOMAIN statement is used to define a new data type for columns in a table.
