ERP provides an integrated view of core buisness processes, often in realtime, using common databases maintained by a database management system. ERP systems track business resources cash, raw materials, production capacity & the status of buisness commitments: orders, purchase orders, and payroll. The applications that make up the system share data across the various departments (manufacturing, purchasing, sales, accounting, etc.) that provide the data. ERP facilitates information flow between all buisness function, and manages connections to outside stakeholders.
