DATA MODELING

Data modeling is a method used to define and analyze data requirements needed to support the business processes of an organization. The data requirements are recorded as a conceptual data model with associated data definitions. Actual implementation of the conceptual model is called a logical data model. To implement one conceptual data model may require multiple logical data models. Data modeling defines the relationships between data elements and structures. Data modeling techniques are used to model data in a standard, consistent, predictable manner in order to manage it as a resource. The use of this standard is strongly recommended for all projects requiring a standard means of defining and analyzing the data resources within an organization

Such projects include:

• incorporating a data modeling technique into a methodology;
• using a data modeling technique to manage data as a resource;
• using a data modeling technique for the integration of information systems;
• using a data modeling technique for designing computer databases.
