What are the main differences between CoM and relational model?
Below we describe some most important differences between these two approaches: • The relational model is based on set theory and set operations while the concept-oriented model is based on lattice theory and ordered set to describe its syntax and semantics. • The relational database manages records in tables while the concept-oriented model manages item connections because each item is defined via other items and an isolated item does not have its own non-primitive semantics. The concept-oriented semantics is intrinsically distributed over all items rather than encapsulated in one record. • The concept-oriented model is intrinsically multidimensional and hierarchical while the relational model in this sense has a flat structure because tables are not ordered. In the relational model table do not have a concrete position in the space of other tables. Even if we can imagine such a space the database does not take it into account. In contrast, for the concept-oriented model the position
