In chapter 5 I tried to define some concepts that are on Conceptual
Model (CM) level.
However they are very related to RM level.
Example 2.5 on my web article has relation with the states.
The states of a relation are defined similarly as the entity's states
(the states are knowledge).
Example 2.5 can be more complex in real life and it is appropriate to
introduce the states
Chapter 4 is about the decomposition into the binary relations.
The idea is to create the relations so that each relation has a simple
key.
Then the binary decomposition is by the simple key.
In this sense idea is simple.
