Data Modeling creates a visual representation of a data system as a whole or as parts of it. The goal is to communicate the kinds of data being used and saved within the system. A data model should also show the data’s relationships, how the data can be organized, and the formats used.
A data model can be used to define and analyze an organization’s data requirements and support predictions for future needs. Typically, the Data Modeling process requires getting professional data modelers to work closely with management, as well as the people who will be working with the data.
