In this post I will present a large part of the real business that belong to databases. Some problems in this big business area can not be solved by using "Anchor Modeling" at all. These problems may occur in any database. In a real business world this case is happening on a daily basis.
In real-world business, errors happen frequently at data entry level. It often happens that data entry generates large amounts of erroneous data. So this is a real and big problem. My database solution can solve this problem. "Anchor modeling", RM / T and 6NF can not solve this problem. As far as I know only my database solution can solve this problem.
Anyone who uses the "Anchor Modeling" database can enter incorrect data. This is possible because the authors of "modeling anchors" have written that the erroneous data can be deleted.
Example
Some math professor gave the best grade to the student who had the worst
grade. In this school, professors enter grades in database. This student
gave money to the professor for this criminal service. The student managed
to enroll at the university using this false grade.
After a summer holiday, the math professor returned to school and he deleted
the false grade, then he entered the correct grade in the database. In this
school they use "Anchor Modeling" db. So the math profesor deleted false
data as it is proposed and strictly suggested by authors of "Anchor
modeling".
This example says that using "Anchor Modeling," you can do crime with data
just by applying „Anchor modeling technology“
In section 5.4 the authors of „Anchor modeling“ wrote the following: „Delete statements are allowed only when applied to remove erroneous data.“
Authors of "Anchor Modeling" claim that their data model can maintain a history.
As „Anchor modeling“ allows deletion of data, then "Anchor modeling" has all the operations with the data, that is: adding new data, deleting data and update. Update can be obtained by using two operations: first delete the data, then add new data.
This further means that Anchor modeling has no history, because it has data deletion and data update.
