). Besides object types, the terminology model allows defining hierarchical classifications, definitions for object type and property behavior and definition of casual relations. The terminology model is a means for subject matter experts to express their knowledge about the subject in subject specific terms.

database schema The database schema is the structure of a database described in a formal language supported by the database management system (DBMS). The term " schema" refers to the organization of data as a blueprint of how the database is constructed (divid ...

. Thus, the terminology model is a method for problem analysis on the one side and a mean of defining database schema on the other side. Several terminology models have been developed and published in the field of statistics: * Terminology model for classifications * Terminology model for statistical variables * Reference model for statistical metadata METANET - Reference Model
