Abstract: With the fast development of marine geological work, the amount and types of data increase rapidly. Data warehouses are expanding and data collection and utilization become busier and busier, in addition to daily management load. Manual operation is no longer able to meet the increasing needs. It urgently needs a data management system for data archiving, cataloging, storage, utilization and service for the public. In this paper, we provided the readers with an design of a data managment system based on database technology, network technology, web technology and software development. The system has not only effciently educed the daily work, but also greatly improved the data sharing within scientists and the service to the public.
