Data Modeling :

It is an integral part of Business Intelligence system and its respective designing.

According to the concepts of the BI and the components there are three basic types of data models that are widely available :

a) Conceptual Data Model :

This represents the highest level of the relationships between the different entities. The targest for this data model is generally the business owners, BA, and Architects. It clearly describes the process or the semantics of a domain or even clearly the scope of the model. This specifies the kinds of facts or the propositions that can be expressed using the model.

b) Logical Data Model :

This represents the basic entities, attributes, and relationships that are used and are involved in a business function and helps as the backbone for the creation of the physical data model that is preceeding this model. It describes the structure of a some domain of the information. This consists of descriptions of the tables, columns, object-oriented classes, and XML tags. Somtimes the logical data model and the conceptual data model are combined to form as a one and the same.

c) Physical Data Model :

It generally represents an application and particularly a database specific implementation of a logical data model and defines the respective database objects. This is concerned with partitions, CPUs, tablespaces.

In all the models, that data is designed in particular for a different level of audiences.
