HISTORY OF DBMS
In the 1960’s the first DBMS was developed at IBM and was originally called IMS, written for the Apollo program.
In the 1970s, Edgar Codd thought of a way to make things a bit easier. 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.
