Schema Version: 1.3

stockprop


Description

A stock 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, stockprop_c1, for the combination of stock_id, rank, and type_id. Multivalued property-value pairs must be differentiated by rank.
