How to create a data model?

Creating a data model involves designing a representation of the underlying structure and organization of a database. To create a data model, you first need to understand the requirements of the system and identify the entities or objects that need to be represented. Then, establish relationships between these entities by defining their attributes and identifying the primary and foreign keys. Next, determine the cardinality and modality of relationships, ensuring proper normalization to minimize redundancy and achieve data integrity. Finally, document and communicate the data model using diagrams like entity-relationship or UML diagrams to provide a visual representation that stakeholders can understand and validate. Iterative refinements based on feedback and potential changes in requirements may be necessary during the data modeling process.
