SAP R/3:
-------------
SAP R/3 is the former name of the enterprise resource planning software produced by SAP AG. It is an enterprise-wide information system designed to coordinate all the resources, information, and activities needed to complete business processes such as order fulfillment or billing.
History of SAP R/3:
-------------------------
The first version of SAP's flagship enterprise software was a financial Accounting system named R/1 called as YSR. This was replaced by R/2 at the end of the 1970s. SAP R/2 was in a mainframe based business application software suite that was very successful in the 1980s and early 1990s. It was particularly popular with large multinational European companies who required soft-real-time business applications, with multi-currency and multi-language capabilities built in. With the advent of distributed client–server computing SAP AG brought out a client–server version of the software called SAP R/3 (The "R" was for "Real-time data processing" and 3 was for 3-tier). This new architecture is compatible with multiple platforms and operating systems, such as Microsoft Windows or UNIX. This opened up SAP to a whole new customer base.
SAP R/3 was officially launched on 6 July 1992. It was renamed SAP ERP and later again renamed ECC (ERP Central Component). SAP came to dominate the large business applications market over the next 10 years. SAP ECC 5.0 ERP is the successor of SAP R/3 4.70. The newest version of the suite is SAP ECC 6.0.

SAP NetWeaver:
-----------------------
SAP NetWeaver is SAP's integrated technology computing platform and is the technical foundation for many SAP applications since the SAP Business Suite. SAP NetWeaver is marketed as a service-oriented application and integration platform. SAP NetWeaver provides the development and runtime environment for SAP applications and can be used for custom development and integration with other applications and systems. SAP NetWeaver is built using primarily the ABAP programming language, but also uses C (programming language), C++, and Java EE. It also employs open standards and industry de facto standards and can be extended with, and interoperate with, technologies such as Microsoft .NET, Java EE, and IBM WebSphere.
SAP NetWeaver's release is considered as a strategic move by SAP for driving enterprises to run their business on a single, integrated platform that includes both applications and technology. Industry analysts refer to this type of integrated platform offering as an "applistructure" (applications + infrastructure). According to SAP, this approach is driven by industry's need to lower IT costs through an enterprise architecture that is at once (1) more flexible; (2) better integrated with applications; (3) built on open standards to ensure future interoperability and broad integration; and, (4) provided by a vendor that is financially viable for the long term.
SAP is fostering relationships with system integrators and independent software vendors, many of the latter becoming "Powered by SAP NetWeaver".
SAP NetWeaver is part of SAP's plan to transition to a more open, service-oriented architecture and to deliver the technical foundation of its applications on a single, integrated platform and common release cycle.
