3. Types
Of
Database

6. History:
The first ever created computers were overly
expensive and did not have separate terminals. Thus,
the need for centralized computing quickly arose. As a
result, a way for data to be not just processed, but to
also be organized and stored was discovered. This gave
way to the earliest versions of databases, their
respective database management systems (DBMS) and,
in turn, centralized databases.
An example for a centralized database could be given
with the Australian Department of Defense, which
centralized their databases in the mid 1970s.
