Abstract: The method to design the Database Management System(DBMS) for marine geological survey is introduced. The characteristic of the general structure, functional modules and database is analyzed, on the basis of which, the main functions of this system are implemented. The method to implement the key functions such as distance and area measures, contours generation, spatial distribution analysis is also discussed. It has certain reference value to similar GIS designs and practice.

Key words: marine geology, Geographic Information System(GIS), database, component-based development
