The establishment of the database, mainly the requirements of the collation and classification. such as: On the machine need to know what date, what time, which card to carry out the machine operation; registration needs to know the basic information of the registered object, and which operator is registered and so on. The following nine tables have been preliminarily established and perfected in later use.

The function of the computer room is around these several tables, the data is increased and censored. A note in a use case diagram is a data table used for a specific function.
