Filed: 2000-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a test data managing system capable of enhancing the workability at a job site while ensuring GLP(Good Laboratory Practice) and capable of reflecting the view of the job site without omission. SOLUTION: This test data managing system is used for managing test data obtained as a result of test, and equipped with a data input means 3 for inputting test data, an attribute input part 11 for inputting attribute data to be individually given to the inputted test data, and an input data storing part 4 for storing the inputted data and the attribute data connected therewith. Attributes, such as time of data collection, are connected with test data and stored, on the basis that it is important to attribute data connection to manage test data not by the actual date of collection but by a timing (nominal date) specified by a protocol. This makes possible flexible data collection not depending on a schedule but according to the need of sudden data collection or to the circumstances of the test/research site.  The workability at the site is sharply enhanced while the GLP, etc., are ensured, and the collected data can be surely reflected in the test results.
