ERP systems are accounting-oriented information systems for

identifying and planning the enterprise-wide resources

needed to take, make, distribute, and account for customer

orders. ERP systems were originally extensions of MRP II

systems, but have since widened their scope. An ERP system

also differs from the typical MRP II system in technical

requirements such as relational database, use of objectoriented programming language, computer aided softwareengineering tools in development, client/server

architecture, and open system portability.
