Ship structure data exchange based on standard data access interface

In order to eliminate information isolation island and realize ship data integration among different systems,a method of ship structure data exchange was proposed based on Standard Data Access Interface(SDAI).The expression method of ship structure data was presented,mapping rules from EXPRESS to relational database were established.And environment of SDAI was analyzed.On this basis,a system model for ship structure data exchange based on SDAI was set up.The model was used to implement the ship structure application protocol AP218.The system implementation architecture for ship structure data exchange between Tribon and SPAR was developed.And prototype system was implemented.
