The abstract representation of the contents of a database is called the logical data model. It defines the structure of the data and how the data is organized but does not specify the physical implementation details such as storage or access methods. A data dictionary is a catalog of all the data elements in the database, a data relationship describes how the various data elements are related to each other, and subschemas are subsets of the logical data model that define a specific view of the data for a particular application or user group.
