1. This technology relates to the technical field of industrial big data, in particular to product history query methods, devices, equipment and media.
Background art:
2. The production execution system (mes) stores the production history of products and records the production information of products in the manufacturing process in detail. Through the production history of products, we can trace the source of the problem products and narrow the scope of product recall, thus reducing the losses caused by recalled products. Traceability data model can not only record the production process data completely, but also be extended to quality traceability, procurement traceability and other aspects, which is of great significance to the control and improvement of enterprise manufacturing process.
3. The product history tracing is usually based on the data stored in the relational database, but the product history tracing based on the relational database has some problems such as long or complex query process, which leads to the low efficiency of product tracing.
