Identification is one of the most important parts of information systems because the biggest number of queries to database management systems are not related to selection of some set of data which constrained by criterias, but to receiving data about specific object or instance of its class.

Identification of objects is basic or even elementary process which are refered to recording of the objects, to the matching of objects with internal data and as a result with the selecting of data.

Frequently we are faced the situations when incorrectly defined criterias of identification, classification of objects, defining of identifies in business systems critically reflect on the success of work of the information systems and business processes in general.

Therefore research in this area allows to define and avoid a number of issues arising in designing of information systems architecture.
