Logical Data Modeling - first of all this is the process of identifying. Also it is the process of modeling and documenting the data requirements of the system being designed. The data is separated into entities (things about which a business needs to record information) and relationships (the associations between the entities). (2)
Data Flow Modeling - it is shows the process of identifying, modeling and documenting how data moves through a System of information.
