Re: The original version

I would like to emphasize that changes of states are associated with a lot of important things :

In my paper the concept of a state is constructed using new ideas about concepts. This concept is not defined only by means of attributes. Aside from attributes, it involves constructs which are related to knowledge, identification and semantics of states of entities.

Regarding states of entities, I use abstract objects which are interpretations and abstractions of the real objects. An abstract object satisfies the corresponding concept. This means that real objects do not satisfy (directly) concepts, rather the corresponding abstract objects satisfy the concepts.

The objects from database represent the abstract objects. I introduce a state of an entity as knowledge about the entity. An identifier of a state of an entity is determined with knowledge about the entity. This identifier identifies the corresponding state of the entity. This state (in the database) represents the corresponding abstract object, i.e. represents knowledge about the entity. (see 4.2.4)

If I need, I can construct a real identifier of the state of the real entity which corresponds to the identifier of the state from the database. See 6.5.(ii), (page 15) for this construction.

An identifier of a state of an entity allows decomposition of the concept of the state to binary concepts. The same hold true for relations.
The identifier of the state of an entity provides straightforward mapping between the binary schemas as well as inverse mapping.

The meaning of an entity is determined by the semantic properties of its states.
(In my paper I use term m-entity and m-states)

There is one interesting example in philosophy which is related to states:
Entities e1 and e2 have the same attributes. There are 100 states: s1, s2,…,s100. Entity e1 changes its states starting from state s1 to state s100. Entity e2 changes its state from state s100 to s1. At one moment in time both entities will be in state s50. If each entity can somehow jump into position of another entity then both entities will continue their travel to their past.
