Schema Version: 1.3

dbprop


Description

An external database can have any number of slot-value property tags attached to it. This is an alternative to hardcoding a list of columns in the relational schema, and is completely extensible. There is a unique constraint, dbprop_c1, for the combination of db_id, rank, and type_id. Multivalued property-value pairs must be differentiated by rank.
