Ambiguous Use of the word "entities"

The use of the word "entities" is a bit confusing. Entity seems to be used to refer to a CLR type (mapped to a database table). Given this, it is not clear if entities refers to multiple CLR types or individual Entity "instances". It may be good idea to use the same terminology everywhere (other pages use the term "entity instances"..).
