Question

.database file in Integration Services project

Asked by: ValentinoV

When creating a new Integration Services project, one of the files that gets created has got a .database extension.  More precisely, when the project is called "Integration Services Project1", the file will be called "Integration Services Project1.database".

The content of the file seems to indicate that it is related to Analysis Services.  And indeed, when checking the files created for an Analysis Services project, there is a similar file present.
I also noticed that the BIDS will recreate such a file when deleted.  Furthermore, when an SSIS project gets renamed

Does anyone know the purpose of this file?

The reason for my question is because I am experiencing some strange behaviour related to this file.  Our projects are located in TFS (Team Foundation Server) and we are working with two developers on the same projects.  For some reason BIDS will create a new file with a name like "Integration Services Project1 1.database", and I'm trying to find an answer on why this is happening.
Until now my conclusion seems to be that this is a user-specific file and should not be put under source control.

Any input on this is appreciated!

It could be that the project file (.dtproj) is not pointing to that .database file correctly so it's recreating the same thing with a one at the end.  Check the dtproj file and make sure it's in there correctly.  I guess renaming the project doesn't always change the references.  That would be especially true if someone renamed the project from windows explorer and not from BIDS.

Okay, I've figured out what happened.  I had renamed my project, forinstance from "Integration Services Project1" to "New ProjectName". This caused the creation of a new .database file: "Integration ServicesProject1 1.database", probably because the original file is read-only(stored in TFS and not checked out) and BIDS doesn't know that itshould check out that file.  The newly created file is the onereferenced in the .dtproj file.  The renaming of the project was thenchecked in into TFS but the newly created file was not.
That was partone.
The next part is my colleague who then opened the project and gota message saying that "Integration Services Project1 1.database" couldnot be found, for obvious reasons.

I solved it be manuallychanging the .dtproj file so that it references the original .databasefile and by updating the original .database file with the content ofthe newly created one.  After putting those changes into TFS, mycolleague could open the project just fine, without any popups.
Another lesson learned.

stelth240: what you've described is indeed also correct, although in my situation it was not the full story.  Seems that the integration with TFS is not always perfect.

I've taken a closer look at both files (dtproj and database) and as far as I can tell, it seems that an SSIS project uses the same XML schema as an SSAS project for their project metadata files.  Furthermore I think the only reason that the database file exists is to store the project name (when dealing with SSIS projects).  Then again, the BIDS is able to recreate the file if it doesn't exist.

I'll leave the question open for a while in case someone has some additional info to share on this subject.

I'm glad it was an easy fix and wasn't too involved.  It's interesting that that file's there since I don't see a need for it other than what you mentioned.  I'd really like to know though what exactly that file's for.  I'll maybe keep looking around to see if I can figure out what it's for.
