Data Modelling is the process of producing a data model for the data that we want to store in the database. A data model highlights the essential data and how we must arrange that data. Data models assure uniformity in the naming conventions, and security semantics while assuring the data q...
Data modeling (data modelling)is the process of creating a data model for the data to be stored in a database. 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 da...
