For Sandvik Chomutov precison Tubes Ltd. we created a system used in quality management. In this system, recorded a record of materials used in the manufacture of ovens, including records of laboratory tests carried out subsequently. The structure of information and interaction between the individual records is quite complicated - some data specific to the material batch (lot), then for some specific order or product packaging. The system is deployed as a network application, and automatically alerts among others, are the values observed in laboratory-defined limits.
