Abstract: This paper describes a kind of component with dynamic composition characteristics, presents how to standardize interface and message passing of reusable units in details, and then introduces component composition rules and message passing protocols.It also briefly introduce; implementation of component library that bused on object-oriented database.Finally, it describes a prototype of component reuse supporting environment that we have developed.
