    • A computing system for a data processing apparatus which carries out data processing using a formula. The system includes a link data file for storing formulas which are described by command names assigned to data elements and operation symbols which define operation between the command names, an actual data file for storing actual data in correspondence with the command names in the formulas managed by the link data file, and a computing file for operation processes for computing the operation contents of the operation symbols in the formulas managed by the link data file. A process is provided for specifying a requested formula which is to be computed by referring to the link data file in response to a computation request, reading from the actual data file the actual data corresponding to the command names in the specified formula and reading from the computing file the operation processes corresponding to the operation symbols in the specified formula, and carrying out operations of the operation processes read from the computing file with respect to the actual data read from the actual data file.
    • 一种用于使用公式执行数据处理的数据处理装置的计算系统。 该系统包括用于存储公式的链接数据文件,这些公式由分配给数据元素的命令名称和操作符号来描述,操作符号定义了命令名称之间的操作,用于存储实际数据的实际数据文件与由 链接数据文件和用于计算由链接数据文件管理的公式中的操作符号的操作内容的操作处理的计算文件。 提供了一种处理,用于通过响应于计算请求来参考链接数据文件来指定要计算的请求公式,从实际数据文件读取与指定公式中的命令名称对应的实际数据,并从 计算文件对应于指定公式中的操作符号的操作处理,并且执行从计算文件读取的关于从实际数据文件读取的实际数据的操作处理的操作。

    • A data retrieval system for a relational database, for retrieving a relational table in a relational database having parts separately identifiable within the system. A link data file stores link data which include parts descriptors that describe command names assigned to parts located at table item positions of the relational table, attribute descriptors which which describe command names of parts arranged in a row of the relational table corresponding to the command names described by the parts descriptors, and mode descriptors which describe command names of parts arranged in a column of the relational table corresponding to the command names described by the parts descriptors. An actual data file is provided for storing actual data related to the command names of the parts which form the relational table. A link process responds to requests for retrieval from the relational table. The link process obtains a command name corresponding to a retrieval request by referring to the link data file and then obtains the actual data described by the command name, from the actual data file.
    • 一种用于关系数据库的数据检索系统,用于检索关系数据库中的关系表,其中具有可在系统内单独识别的部分。 链接数据文件存储链接数据,该链接数据包括描述分配给关系表的表项位置的部分的命名名称的部件描述符,其描述了排列在与命令名称对应的关系表的行中的部件的命名名称 由描述符描述的描述符以及模式描述符描述了与由部件描述符描述的命令名对应的关系表的列中的部件的命令名称。 提供实际的数据文件用于存储与形成关系表的部分的命令名有关的实际数据。 链接过程响应关系表中的检索请求。 链接过程通过参考链接数据文件获得与检索请求对应的命令名称,然后从实际数据文件中获得由命令名称描述的实际数据。
