Data Modeling 

data modeling

A data model organizes elements of data and indicates how they relate to each other and to real world entities thus enabling formulate a system. They support the development of information systems. It helps in abstract formalization of various system elements thus enabling the transformation of an idea or virtual system into a documented hierarchical and systematic diagram pr data model. 

business model integration

Business Model integration of a data model requires understanding how a system is placed within a business model. It helps link the system with the business process and thus helps clearly depict the relation between the data model, information systems and business processes. 

different data model

There are different data models that can be formed. This includes a flat model, hierarchical model, network model, relational model, object relational model and star schema. This is based on the number of data array, number of data dimensions of data elements and the structure of the links in the models. 

data model for business process

A data model for your business process can be chosen out of these 3 popular types:

  1. Conceptual data model: It describes the semantics of a domain and the scope of the model. For example, it indicates a particular segment in an organization or industry. 
  2. Logical data model: It describes the semantics based on a data manipulation technology. It consists description of data, tables, columns, object oriented classes, and XML tags. 
  3. Physical data model:  It describes the physical means by which data is stored including partitions, table spaces and CPU
