History of the database - what literature can be referenced?

Question

Database

Hello! I am writing a paper on granting legal protection in relation to databases. It is necessary to briefly talk about the appearance of the first DBMS (IMS, as I understand it) and the concept of a database as a whole. But the fact is that you need to refer to something authoritative and better in the public domain. Links to Wikipedia in the article are not acceptable.

Answer 1

see the works of E. Codd and K. Date
