1. An information processing system which utilizes apparatus data recorded in a database in conformity with a data definition which can be updated as needed, the system comprising:

  • a storage unit configured to store a data definition history in which a data definition version is associated with a period for which a data definition in the data definition version is used, the data definition history being updated in accordance with updating of the data definition;

    a data definition library configured to register a data definition version and a data definition in the data definition version in association with each other;

    an extractor configured to extract, from the database, apparatus data which meets an extraction condition including an extraction period designated via a user interface; and

    a converter configured to convert an expression of the apparatus data extracted by the extractor into an expression conforming to a data definition designated via the user interface,wherein the apparatus data is one of data generated by a semiconductor manufacturing apparatus and data obtained by processing the generated data, andthe converter is configured to determine a data definition version of a data definition used within the extraction period by referring to the data definition history, to determine a data definition in the determined data definition version as a data definition of the apparatus data extracted by the extractor by referring to the data definition library, and to convert an expression of the apparatus data into an expression conforming to the designated data definition.
