Terminology-oriented database
Template:New unreviewed article
A terminology-oriented database [management system] is a conceptual extension of an object-oriented database[1]. It implements concepts defined in a terminology model. Compared with object-oriented databases, the terminology-oriented database requires some minor conceptual extensions on the schema level as supporting set relations (super-set, subset, intersection etc.), weak-typed collections or shared inheritance.
The approach of a terminology-oriented database is a conceptual rather than a technical. The terminology-oriented database provides facilities for transforming a terminology model provided by subject area experts completely into a database schema. The target schema might be the database schema for an object-oriented database as well as a relational database schema, or even an XML schema. Typically, terminology-oriented databases are not bound on a specific database type. Since the information content, which can be stored in object-oriented databases and in relational databases, is identical[2], data for a terminology-oriented database can be stored theoretically in any type of database as well as in an XML file. Thus, terminology-oriented databases may support several database systems for storing application data.
