This history is archival in nature ie. A network model called CODASYL and a hierarchical model called IMS. Databases collections of related data are as old as the written word.

Microsoft Access is a database management system from Microsoft that combines the relational Microsoft Jet Database Engine with a graphical user interface and software-development tools. In computing a database is an organized collection of data stored and accessed electronically from a computer system. Microsoft Access stores data in its own format based on the Access Jet Database Engine.

Initially they were a solution to the problem of storing and protecting the things we wrote down and making it. The full form of DBMS is Database Management System. A database can be anything from a homemakers metal recipe file to a sophisticated data warehouse.

Phase I took place from roughly the 1960s to 1999 and included the development of Database Management Systems DBMS known as hierarchical inverted list network and during the 1990s object-oriented Database. Although an electronic version such as one created in Microsoft Access may be the first that comes to mind there are many non-automated database versions as well such as a personal phone and address book.

It took place from roughly 1960 to 1999. No changes to structure is necessary for new tables.
