Enterprise Resource Planning
ERP

    (ERP) Any software system designed
   to support and automate the business processes of medium and
   large businesses.  This may include manufacturing,
   distribution, personnel, project management, payroll, and
   financials.

   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 object
   oriented programming language, computer aided software
   engineering tools in development, client/server
   architecture, and open system portability.

   JBOPS are the major producers of ERP software.
