This module will facilitate comparative methods and analyses in Chado. It mainly consists of the grp (group) table and supporting tables.
You could potentially link an organism and a feature (and anything else with a grpmember linker table) to the same grpmember_id.
Current schema is incompatible with chado-xml.
Should grpmember have a type_id column?
Tables in blue would be part of the Comparative module proper, while tables in red would be part of submodules.
Not shown: grp_cvterm, analysisgrpmember
