As I wrote, my data model can model a world. It is about small worlds that can be used in industry, medicine, software solutions etc. The following two things related to the world are the most important:
(i) The world can maintain its past, present and future.
(ii) The main control part of the world is a collection of information,
i.e.data from the appropriate database. This means that the "control
part" controls the world by information, that is, by using the data,
that is, using a DB.
I will now give an example of "the world", so that it is clear, what it is
about. Suppose we need to make an artificial knee. For this purpose we will
define all the processes which exist in the knee, and which may be executed
in the combination with other processes or they can be performed alone.
This all depends on the various movements in the knee that we wish to make.
So some processes in the knee are willing (they come from the brain) and
some are automatic.
In other words, the world from this example takes information with relevant
data for the execution of programs that implement the appropriate processes
in this little world, that is in the knee. Note that my programs do not have
start and end.
Gurevich's algorithms have "start" state" and "end" state. In my solution,
we can run just a state of the corresponding program. If we need we can run
just a part of a state of a program.
It is now clear that the "history of the future" of this world (in this example it is the world of the knee) is completely determined with database that keeps the states of programs. From this database, we can run any of series of the states of programs. This database, also can memorize the history of events of these programs that were executed.
Thus, these solutions can be applied everywhere where we have a set of programs. Many important problems are not matter of one algorithm. We often have sets of programs and programs with different states. Let me mention "cloud computing", operating systems, and industry. To my knowledge no one has offered to these problems a serious theory. So this is a matter of database theory. It is not covered with Gurevch's algorithms.
