It provides high-level operations for querying the data. ● The model is conceptually simple, allowing application programmers to be able to quickly grasp the important concepts they need to get started with their work. ● The model is based on a mathematical structure, which allows many operational aspects to be proved, and the operations have well-defined properties. ● It’s easy to modify and add to relational databases. ● The same database can be represented with less redundancy. This is a pretty comprehensive list of the advantages of modeling your data relationally before you commit yourself to a physical design.

We’ve discussed the varied goals and team positions of data modelers and shown how they can be just about anyone involved in data management, since data modelers are involved in all aspects of data design, build, maintenance, and rediscovery.
