Data Base Task Group

The Data Base Task Group (DBTG) was a working group founded in 1965 (initially named the List Processing Task Force and later renamed to DBTG in 1967) by the Cobol Committee, formerly Programming Language Committee, of the Conference of Data Systems Language (CODASYL). The DBTG was chaired by William Olle of RCA.[1]

In April 1971, the DBTG published a report containing specifications of a Data Manipulation Language (DML) and a Data Definition Language (DDL) for standardization of network database model. The first DBTG proposals had already been published in 1969. The specification was subsequently modified and developed in various committees and published by other reports in 1973 and 1978. The specification is often referred to as the DBTG database model or the CODASYL database model. As well as the data model, many basic concepts of database terminology were introduced by this group, notably the concepts of schema and subschema.

gollark: That's quite boring.
gollark: And you can make lots of cool high-efficiency ore processing setups.
gollark: I mean, turtle quarries are meant to do that, they are just not able to do it very well right now.
