Logical Data Model



/ˈlɑʤɪkəl ˈdeɪtə ˈmɑdəl/




An abstract representation of an information system in the form of a chart containing relational data tables called entities as well as their relationships to each other.

Each entity within a logical data model will contain necessary fields captured by the entity. A logical data model differs form a physical data model in that the data model does not specify the technical framework necessary for implementing the data model and differs from a conceptual data model, which only describes the business requirements of an organization without the use of data structures.
