Data Modeling

Data modeling is a way of mapping out and visualizing all the different places that a software or application stores information, and how these sources of data will fit together and flow into one another. This is a hugely important stage in the design process for any business-critical IT system.

When developers are figuring out how a new system will work, they establish what the most pressing needs of a business are, what kind of data they’ll need to access in order to meet those needs, and how the data will be used. From there, they can start to create a diagram (or model) of how each pocket of data will flow into each other, and how they’ll interact.

What is the importance of data modeling?

Without a design method that results in a well thought out data model then you’ll end up with a database that will not meet user requirements in the short and long term. It will not adapt to simple changes well, requiring additional overhead by programmers to work around structural anomalies (mistakes). See the full article for more details.
