Blackhole data architecture and flow can be outlined in the following diagram: <diagram missing> In brief, there's a central database into which unrelated systems push data describing contributions. This data can be queried very broadly (eg. show me contributions by a certain user; show me contributions made during a certain period; show me a certain type of contribution), as well as with very deeply (eg. show me Bugzilla triage contributions for the Firefox product). All data stored has a small amount of commonality, describing where it came from, who contributed, when they did it, and how to find the original contribution. Further information available varies per type of contribution, so Blackhole users can query specifically for it if they're interested.
