A conceptual schema or conceptual data model is a high-level description of informational needs underlying the design of a database.[citation needed] It typically includes only the main concepts and the main relationships among them. Typically this is a first-cut model, with insufficient detail to build an actual database. This level describes the structure of the whole database for a group of users. The conceptual model is also known as the data model that can be used to describe the conceptual schema when a database system is implemented.[citation needed] It hides the internal details of physical storage and targets the description of entities, datatypes, relationships and constraints.
