What is Data Modeling? |
|
Answer» Data Modeling is the act of CREATING a visual representation of an entire information system or parts of it in order to express linkages between data points and structures. The purpose is to show the MANY types of data that are used and stored in the system, as well as the relationships between them, how the data can be classified and arranged, and its formats and features. Data can be modeled according to the needs and requirements at various DEGREES of abstraction. The process begins with stakeholders and end-users providing information about business requirements. These business rules are then converted into data structures, which are used to create a CONCRETE database design. |
