Ask HN: Tool to map business processes to data fields?

Is there a tool that maps Businesses Processes to their database objects/fields? Don't need automated discovery. But should be a collaborative system, where different users can run reports and see potential conflicts. For example, a field used by one process may be overwritten by another process. The tool should list business process, business process owner, field, field owner(s). I can make a homegrown system but was wondering if there is cheap tool already made for this.
