What is Data Modelling Techniques?
Data modelling is the process of defining how data is structured and related within a storage system. Common techniques include entity-relationship (ER) modelling for transactional databases and dimensional modelling (star and snowflake schemas) for analytics. The choice of model affects query performance, flexibility, and how easy it is to evolve the schema over time.
