    摘要： The method and system for retrieving information allow the user to retrieve desired information from database systems by simply specifying retrieval content and retrieval conditions using languages familiar to the user, without having to know the names for the relevant database systems or their structures or without having to interact with the platform of the meta-information, i.e., information concerning the use of database systems and accessing method. The present method allows retrieval of information from different database systems connected to a communication network, by using reference information stored beforehand to access different database systems; consulting the reference information to determine database systems which contains data to satisfy the information retrieval request by converting requested items to equivalent related words that the system can recognize. The storage locations of the data and instructions on how to acquire the data are determined using relational items to link various tables so that an information retrieval statement can be prepared by the system program on user's behalf. The databases are searched according to the acquiring method and the information retrieval content described in the system prepared statement, and the retrieved information is presented for viewing in a format that is used by the information searcher.

    摘要翻译： 用于检索信息的方法和系统允许用户通过简单地使用用户熟悉的语言指定检索内容和检索条件来从数据库系统中检索所需的信息，而不必知道相关数据库系统或其结构的名称，或者不必 与元信息的平台交互，即有关使用数据库系统和访问方法的信息。 本方法通过使用预先存储的参考信息来访问不同的数据库系统，允许从连接到通信网络的不同数据库系统检索信息; 参考参考信息来确定数据库系统，其包含通过将所请求的项目转换为系统可识别的等效相关词来满足信息检索请求的数据。 使用关系项目来确定数据和关于如何获取数据的指令的存储位置以链接各种表格，使得可以由用户代表的系统程序来准备信息检索语句。 根据获取方法和系统准备语句中描述的信息检索内容来搜索数据库，并且以由信息搜索者使用的格式呈现检索到的信息以供查看。
