The first product of CODASYL is the programming language COBOL , a further development of standardized methods for defining the structure ( Data Definition Language ) and processing ( Data Manipulation Language ) from the network database systems , which in this form as CODASYL databases are known to carry the Data Base Task Group (DBTG).
