英文摘要：

Research on the efficiency and space of data storage for underwater vehicles is conducted. The application of embedded database Berkeley DB and RDM in Underwater Vehicles is discussed and the usage methods are introduced. According to the experiments requirements, the embedded database was designed and the experiments were undertaken. The experiment results are obtained. The validity and feasibility of the embedded database in the underwater vehicles has been verified by analyzing the experiment results. Comparing the experiments results, theory guidance for the underwater vehicles in the application of the embedded database can be provided.
