Answer and Explanation
SQL is a language used for defining (DDL) and manipulating (DML) data in relational databases.
SQL can be passed as-is to the database management system and does not need to be compiled.
Although SQL is standardized and can use the same syntax regardless of the type of database management system, there are parts where SQL is uniquely extended by the database management system.
There are several SQL standards, including SQL86, SQL92, and SQL:1999. The standardization of SQL is promoted by ANSI (American National Standards Institute) and ISO (International Standards Organization).
Therefore, the correct answers are C and D.
