| 摘 要： | 本文首先阐明了数据库的主要类型及其数据结构的特征，然后详细地总结了数据库设计的，方法，步骤。最后，文章分析了大气，海洋观测数据的自然结构特征，指出对其最适宜的数据库类应当是层状数据库，文章还以大气为实例，给出了层状数据库和关系数据库的概念模型，并对二者的存取效率作了对比，结果证迷产了文章中的观点。

| Abstract: | This paper discribes first the main types of database and their corresponding data structure, then summaries the procedure for database design. At last,based on an analysis of data structure nature of atmospheric and oceanicobservations, the paper proposes that the best database type for these observations should be hierarchical database, and gives the conceptual .schemaof hierarchical and ralational database for them as an example, and alsomakes a comparison of access efficiency for the tiro databases. Result supportsproposed point in this paper. |
