Abstract: The Agency for Assessment and Application of Technology – Indonesia (BPP Teknologi) has collected extensive marine geosciences data in Indonesia‘s maritime area by using the Baruna Jaya I, II and III research vessels. Types of data include: geological/geophysical data (coring, sampling, dredging, bathymetry, heat flow, magnetic, seismic, etc.), oceanography data (water temperature, salinity, sound velocity, chemical concentrations, etc.) and hydrography/meteorology data (air temperature, pressure, humidity, sea current and direction, etc.). A microcomputer database system has been developed using Prolog language for managing the data and it provides the integrated capabilities of database management system and expert system. The database system provides easy data entry, storage and retrieval in which the user could query the data based on the coordinate ranges, types of survey, name of survey, name of vessel and survey location. The output can be displayed in map format or text format and can be imported by some commercial softwares. The expert system provides intelligent assistance in searching specific geological, geophysical, oceanographical and hydrographical/meteorological information. The Prolog declarative expression of the database itself makes the data accessible for any logic or expert system programming. This can be built to suite specific purposes. The system is especially useful for institutions involved with marine data (i.e. oil company, oceanographic institutions, etc.). It is designed as an economical and practical microcomputer based system. The advantages of using Prolog language and Intelligent Database System concept is discussed.
