How concept syntactic structure is represented?
The concept-oriented file system stores also the syntactic structure of the higher level database. A special concept Concepts-Concepts (not shown in the example diagram) stores the syntactic relationships among concept items. It has at least two dimensions both with the domain in the Concepts concept. For each existing concept item from Concepts there exist a number of parent concept items as its dimension domains. All these pairs are stored in the Concepts-Concepts concept as items. In fact the concept Concepts-Concepts should have more dimensions in order to be practically useful. In particular, it may have a name of the dimension and dimension constraints. (Alternatively, dimension names might be a part of the common name system). Each item in this concept describes one dimension in the whole system with all its parameters.
