Data modeling

Data modeling is like making a map of a city. Imagine a toy city made out of Lego blocks. A data modeler would create a map of the city that shows which pieces fit together to create roads, houses, and stores. The map would also show how the various parts of the city fit together. For example, the modeler could show how the roads connect the different houses and stores. Data modeling is like this, but instead of mapping out a physical city, it maps out how different pieces of information fit together in a database or computer system. A data model can show how various pieces of information relate to each other and how they can be organized and used.
