摘　　要：海洋环境数据种类繁多且数量巨大,多数以文档数据集形式存在,这使得海洋环境大规模数据的存储和访问变得困难。针对当前海洋环境大数据存储方法不足和编程访问的局限性,提出了一种面向应用编程的数据存储访问模型。该模型将文件数据模型结构信息映射到虚拟数据库中,提供基于SQL语法的访问接口,降低数据访问复杂度,提高软件编程效率。There are many different kinds of and huge number of marine environment data in a variety of document form,which makes it difficult to retrieve and access.This paper proposed a data access model for application programming in view of the current marine environment huge data storage method and programming access limitations.The model was constructed on the basis of unified file data mode,mapping the file structure to virtual relational database,and could be accessed based on SQL syntax,which reduced the data access complexity and improved software programming efficieng.
