This data model is a conceptual representation of Data objects, the associations between different data objects, and the rules. Data modeling helps in the visual representation of data and enforces business rules, regulatory compliances, and government policies on the data.

Modeling simplifies database design and maintenance by enabling you, the data architect, to visualize requirements and resolve design issues. Model-driven database design is an efficient methodology for creating valid and well-performing databases, while providing the flexibility to respond to evolving data requirements. MySQL Workbench provides extensive capabilities for creating and manipulating database models, including these:. This is not an exhaustive list.
