摘要： 针对当前数据库产品在数据处理实时性上不能满足HLA实时仿真系统的需求，建立了一个运用于HLA实时仿真系统的海洋环境数据库。文章提出了为提高数据读取及发送的速度所采取的两项措施：将数据预先读入内存；采用数组存放环境数据，通过实际使用证明能够满足实时仿真的需要。介绍了数据库的总体结构、功能、内容，数据库的结构建设，环境要素的存储形式，数据采集和仿真数据生成和检索模型等数据库要素的生成。通过实际使用及和当前数据库进行比较，提出了本数据库的优点及有待进一步改进的问题。

Abstract: Aiming at the disadvantages of current databases, a sea environment database is established for the HLA real-time simulation. In first part ,in order to improve the speed of data transfer, two methods are used: data is read in the memory prior to the simulation; using array to store environment data. Then, the frame of database, the function of database, the main content of database, frame construction of the database, saving forms of the environment parameters, collection of environment data and index models are introduced. Finally, compared with current database, advantages and disadvantages of this database are introduced.
