SAP NetWeaver is an application builder from SAP. SAP NetWeaver helps in integrating business processes, business applications and databases from a number of sources using web based services. SAP NetWeaver is thus a technical framework which consists of all components of mySAP ERP, mySAP Business Suite, and the SAP composite applications, referred to as xAPPs. What makes SAP NetWeaver unique is that it is the first fully interoperable web based cross application platform that can be used to develop not only SAP applications but others as well.
