While these specifications were influential, they weren't languages themselves. The DML and DDL concepts they introduced were eventually implemented in various languages, including:
* COBOL: Many early database systems used COBOL to implement the DML and DDL features, as it was a popular language for business applications at the time.
* PL/I: This language was also used for implementing database features in some systems.
* SQL (Structured Query Language): Although developed independently, SQL eventually became the standard language for interacting with relational databases, largely thanks to its simplicity and power, making it widely adopted.
So, while DBTG didn't have its own "adopted languages", its specifications laid the groundwork for many data manipulation and definition languages, including the dominant SQL.
