Entity-relationship model - The entity-relationship model or entity-relationship diagram (ERD) is a data model or diagram for high-level descriptions of conceptual data models, and it provides a graphical notation for representing such data models in the form of entity-relationship diagrams. Such models are typically used in the first stage of information-system design; they are used, for example, to describe information needs and/or the type of information that is to be stored in the database during the requirements analysis.
Entity life history diagram - Entity life history diagram is a graphical model showing how events creat, modify and delete and instance of each entity.
Hertzsprung-Russell diagram - The Hertzsprung-Russell diagram (usually referred to by the abbreviation H-R diagram or HRD, also known as a Colour-Magnitude (CM) diagram) shows the relationship between absolute magnitude, luminosity, classification, and surface temperature of stars. The diagram was created circa 1910 by Ejnar Hertzsprung and Henry Norris Russell.

Sometimes, the word 'entity' is used in a general sense of a being, whether or not the referent has material existence; e.g. God is often referred to as an 'Entity' with no corporeal form.
