* Parent: the parent property in the child is not nullable
* ParentN: the parent property in the child is nullable
* ParentR: the parent property in the child is readonly
* ParentNR: the parent property in the child is nullable and readonly
*
* each activity like create, update or delete is done first in a rooled back transaction and none of the data should
* be changed, then the same activity is executed in a commited transactions and the data should change accordingly.
*
* After a transaction has been committed, the datacontext gets disposed, opened again and verified, that the data
* is still the same. This is done twice, first using the .bak files, then the .csv files. There is one exception:
* stored parents might have some not stored children. In the new data context, those parents have no longer those
* children.
*
* For convenience, the variables parent0, parentN1, child1, etc. contain always the data from the latest data context. They
* get updated, each time assertDataDisposeDCRecreateDCassertData() gets called.
*
* child_, child__, parent_ and parent___ are not stored in the data context. They do not get updated by
* assertDataDisposeDCRecreateDCassertData() and can therefore contain children or parents stored in previous data
* contexts.
