2. New theory about abstract objects and objects from the real world
In my paper "Some Ideas about a New Data Model" presented on my website and
on this user group on September 17, 2005, I have introduced „New theory
related to abstract and real object“. In this new theory it is accepted
that every object has changes during its existence and that it is the same
object that has only changed its states. For example, one man changes his
physical attributes during his life. However, we consider that the person
with the changes is the same as the original person and for the duration of
its existence we use the same name - No matter how much this person has
changed.
In the current theory and practice for the databases we have the following
rule: if an entity changes its attributes then we change the key of this
entity.
In my opinion, current database theory has not solved the problem of changing the states of the objects and the corresponding keys for such objects.
Unlike the existing theory, my solution has the identification of the entity
and has the identification of each state of this entity. This leads to a
new theory of databases. So, I link all the changes to the identifier of the
entity. The identifier of the entity remains fixed, but the entity has
states. In this way the entity does not change, but has states in which it
existed.
This my solution provides a new theory of objects and relationships between
objects.
This my solution shows how some of the most important mental, logical,
semantic and linguistic procedures can be constructed and how they can
be connected.
We also can notice that objects and relationships between objects are very
important concepts in some other sciences.
These authors from the University of Stockholm plagiarized my ideas and my work, that I explained here. They published it as their paper, giving it the name of "anchor modeling".
I presented my solution publicly on this user group on September 2005 and
also on my website.
Paper anchor modeling was presented in December 2009. In this period of four
years, my solution had a lengthy discussion, sometimes it was on a daily
basis. This user group was then the most popular in the world and translated
at more than 10 languages. So my solution was well known.
Since modern databases are based on semantic and logic, then my solution introduces new improvements to an important part of existing semantic theory. And that implies changes in database theory that are of fundamental character. That is why this plagiarism of the authors of "anchor modeling" is actually a plagiarism of important theories in contemporary science.
In this user group, some users have claimed that my identifier of a state of
an entity is a surrogate key. But that's not true. My solution has an
identifier of an entity and an identifier of a state of the entity. A new
idea for identifiers has been applied here - this is the idea that
identifiers can be linked in a variety of ways. My solution semantically
links these two identifiers.
(i) The identifier of an entity is linked with identifiers of states of
the entity.
(ii) The identifier of an entity (which is in the database) is linked with
the corresponding identifier of the entity in the real world. In this
way the identifier of the entity identify entity which is in the memory
(i.e in the database) with the corresponding entity in the real world.
An identifier of states of an entity is always associated with its entity
identifier. In addition, the identifier of states of an entity has many time
oriented data and very complex links between these data. As far as I know,
no other data model can provide such complex links between the real world
and the abstract world. My data model always determines exactly who (or what
procedure) has entered some data. This system for EVERY data can determine
who entered this data into database. So my "key" is not a surrogate key. My
"key" gives a much stronger connection to the real world than any other data
model.
