Function of the system development

System Design Principles
As the MES systems and ERP systems are the two stand-alone system, Mittal Iron and Steel is achieved by different companies, based on two functions of the system complexity, the diversity of business processes, data exchange middleware business major to complete the two systems seamless continuation process, making MES systems and ERP systems to form a coordinated whole, and give full play to the two systems of their respective features. The design of data exchange middleware is mainly based on two systems use the database is ORACLE database, using the background plus front-end interface development model, the background process has been developed using PLSQL languages, make full use of the view, temporary tables, triggers, processes, procedures package, cursor, tasks and other functions, the use of the ERP system, a standard interface table, bonding at the request of the ERP system functions; front interface, based on ORACLE databases FORMBUILDER development tools to develop into our ERP system form articulated in the system, operate directly in the foreground. ERP systems and MES system data transmission, using to create DATALINK data transfer. MES data transmission principle is that the data needed by the ERP is responsible for writing the rules provided by MES interface MES corresponding table; ERP data needed by ERP provided by the MES is responsible for writing the rules of the corresponding ERP interface table.

System business processes
MES to receive ERP provides scheduling order, the receiver module of ERP standard of quality information on the order of quality design, program design process is completed, the request form should be returned ERP task information from the ERP for Import WIP module processing, generation ERP the task of work order information. Upon completion of production, completion performance, investment and material information, product information should be returned ERP systems, energy consumption should also be returned, commuted to retirement the operation alone, the handling of these operations should be associated with the task. MES received the ERP of a library instruction, MES should return after the database is out of ERP performance of a database, ERP decomposition carried out orders, inventory write-down, invoice generation process and other related businesses. System business processes.

The function of the system
Data exchange middleware module from the system divided into functional modules ERP systems, MES systems functional modules, data transfer module; from the business process on the divided orders interface module (common information order, order line information, order the end of information), the task module ( task work order information, production and performance information, investment and material back material information, product information, slab transfer of information), a library module (a library instruction information, a database performance information), retirement commuted module (retirement commuted information). The composition of data exchange middleware functionality.
