What is Data Model?

data model (or datamodel) is an abstract model that organizes elements of data and standardizes how they relate to one another and to properties of the real world entities. For instance, a data model may specify that the data element representing a car be composed of a number of other elements which, in turn, represent the color and size of the car and define its owner.

The term data model is used in two distinct but closely related senses. Sometimes it refers to an abstract formalization of the objects and relationships found in a particular application domain, for example the customers, products, and orders found in a manufacturing organization. At other times it refers to a set of concepts used in defining such formalizations: for example concepts such as entities, attributes, relations, or tables. So the “data model” of a banking application may be defined using the entity-relationship “data model”. This article uses the term in both senses.

What is Data Modeling?

Data modeling is the process of documenting a complex software system design as an easily understood diagram, using text and symbols to represent the way data needs to flow. The diagram can be used as a blueprint for the construction of new software or for re-engineering a legacy application.

Data modelers often use multiple models to view the same data and ensure that all processes, entities, relationships and data flows have been identified. There are several different approaches to data modeling, including:

Conceptual Data Modeling – identifies the highest-level relationships between different entities.

Enterprise Data Modeling – similar to conceptual data modeling, but addresses the unique requirements of a specific business.

Logical Data Modeling – illustrates the specific entities, attributes and relationships involved in a business function. Serves as the basis for the creation of the physical data model.

Physical Data Modeling – represents an application and database-specific implementation of a logical data model.
