Data Modelling
Data modeling is the process of creating a conceptual representation of data and its relationships. It is a technique used in database design and is used to define and organize data requirements needed for a specific application or system.
A data model serves as a blueprint for organizing data and helps to ensure that data is accurate, consistent, and complete. It typically involves identifying the entities (objects or concepts) that need to be represented in the system, their attributes (characteristics), and the relationships between them.
Data modeling involves the use of diagrams, such as entity-relationship diagrams or class diagrams, to represent the data and its relationships visually. The resulting data model can be used to guide the development of a database schema, which is a more concrete representation of the data and its organization.
Data modeling is an important step in developing effective information systems and can help to ensure that the resulting system is well-designed, scalable, and meets the needs of the users.
