I’ve just read this on Ayende’s blog and I’m baffled! I’ve spent quite some time with SSIS, and the most frustrating part is the complete lack of ‘support’ for storing the .dtsx files in a source control system (like subversion). At first glance, everything seems to be ok, as the dtsx files are actually just xml (and thus text) which should be diff’able. However, in practice, it’s a nightmare: every time the file is changed (however small the change you made), a large part of the contents changes and even worse: the changes are clearly not local as they occur all over the place! To make it even better, someone at MS decided it was probably a good idea to store both the ‘code’ (control/data flow logic, …) and the visual representation in the same file! Now even just moving a box 1 pixel messes up the complete file.
And no, the traditional (MS) answer that you should do a reserved checkout simply doesn’t work for 2 reasons
1/ having used the ‘edit-merge-commit’ pattern most of my professional life, I just *refuse* to go back to a checkout-edit-checkin way of working (for one project, I was forced to use VSS, and, to say it nicely, I didn’t enjoy it). This is 2008 you know?!
2/ What about branches and merging? Nope, thought so!
I just cannot imagine that they do not have ‘decent support for teamwork’ as one of their top (non-functional) requirements!! Even the best product (and SSIS clearly is not, IMHO) would be close to useless if it didn’t support this!
