- data model
A database model
can be loosely used to describe an organized and ordered set of information stored on a computer.
This ordered set of data is often structured using a data modeling solution in such a way as to make the retrieval of and changes to that data more efficient.
Depending on the type of applications using the database, the database structure can be modified to allow for efficient changes to that data.
It is appropriate to discover how different database modeling techniques
have developed over the past 50
years to accommodate efficiency, in terms of both data retrieval and data changes.
