[RevisionMachine] ArticleIndex and ChronoIndex procuce multiple entries for some ArticleIDs #76

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The ArticleIndex and ChonoIndex produce multiple entries for some ArticleIDs.
This is a problem - ArticleID is the primary key of the respective tables and 
must be unique.
The duplicate rows are omitted upon import.

Info for the ArticleIndex:
The field "FullRevisionPKs" should contain all PKs of full revisions.
However, in reality, we have several entries for the article each with a 
different FullRevisionPK. The other fields are identical.

Ramifications:
The issue probably causes performance issues, as the first FullRevision is 
found - not the nearest. It should not affect accurancy.

For the ChronoIterator, ramifications are unknown.

Side note:
Of course it SHOULD be normalized - no data structured in the database. As a 
first step, a fix would be enough. In the long run, the fields containing 
structured data should be normalized.

Maybe use RevisionPK from the revision Index instead of RevisionPKs from the 
article index.

While the RevisionPK should still be exchanged with the RevisionID and the 
tables should all be normalized, the problem reported here was a false alarm. 
Everything should be alright.
