A History of Database Management Systems
The history of database management systems begins around the time that computers began taking off. In the 1960's, the concept of the database was put in use and also began to grow in commercial use and it was this rise that was an interest to a man named Charles W. Bachman. Why is Mr. Bachman so important? Well, this is the guy who invented the database management system. Charles Bachman was an industrial researcher, beginning a career at Dow Chemical, where he became the data processing manager in the 1950s before leaving to work at General Electric in 1960.
It was in 1960 that Bachman came up with the Integrated Database System, the very first DBMS. This got the proverbial ball rolling, as Bachman founded the Database Talk Group along with the group that gave the standardization to the programming language of COBOL. Not to be left out, IBM created their own database system, known IMS, for that of NASA's Apollo space program. Both of these are now known as the precursors of navigational databases.
Then in the 1970s, another change was coming. While the above started DBMS, there were in no way easy to use. But then a man named Edgar Codd thought of a way to make things a bit easier. Codd worked for IBM and felt that there had to be a way to make things easier when using these DBMS. He wrote a paper entitled, A Relational Model of Data for Large Shared Data Banks, in which he proposed replacing these current systems with that of tables and rows. This concept would become relational DBMS.
And this is where we are today.
