Data Base Task Group facts for kids
The Data Base Task Group (DBTG) was a special team of computer experts. They were formed in 1965 by a bigger group called CODASYL. CODASYL helped create important computer languages like COBOL.
The DBTG's main job was to figure out how to organize and manage large amounts of computer data. They first called themselves the List Processing Task Force. Later, in 1967, they changed their name to the DBTG. A person named William Olle from RCA led this important group.
What Did the DBTG Do?
The DBTG worked on creating rules for how computer databases should work. They wanted to make sure different computer systems could understand each other's data.
Creating Database Rules
In April 1971, the DBTG released a big report. This report contained important instructions for databases. These instructions included:
- A Data Manipulation Language (DML): This is like a set of commands for adding, changing, or finding data in a database.
- A Data Definition Language (DDL): This is like a blueprint for how a database is built and organized.
These rules were made for a specific way of organizing data called the network database model. The DBTG had actually published their first ideas about this in 1969.
The DBTG Database Model
The rules and ideas from the DBTG were updated over time. Other groups continued to develop them in reports published in 1973 and 1978. Today, people often call these rules the DBTG database model or the CODASYL database model.
New Database Ideas
Beyond just the database model, the DBTG also came up with many basic ideas used in databases even today. Two very important ideas they introduced were:
- Schema: Think of this as the overall plan or structure of an entire database. It shows how all the different pieces of information fit together.
- Subschema: This is like a smaller, specific view of the database. It lets different users see only the parts of the data that are important to them.
The work of the DBTG was very important for how we store and use information on computers today.
