Hi Thasneem,

1.R/3 applications are based on sap basis.

2.ECC 6.0 is based sap WAS ( web application server ). ECC means Enterprise central component.

3.Compared to sap r/3 enterprise, in sap ecc there are architectural changes with respect to enterprise services architecture, enhanced usability and new developed functionality, like the new general ledger.

SAP ERP Central Component, or ECC, and its predecessors R/3 and R/3 Enterprise, are online transaction processing (OLTP) systems—systems that by their very nature satisfy day-to-day transactional needs of typically many users. Within each of these products are a number of modules or submodules (in the case of R/3), or subcomponents at a high level, this includes finance, logistics, human resource management, customer service, and quite a few others.

4. SAP business warehouse, sap strategic enterprise management, and internet transaction server integrated into sap ecc.

customers have the option to run these components on the same instance that runs sap ecc (sap bw and sap sem only on a project basis) to reduce the system landscape and safe costs.

Hi,

SAP R/3 through version 4.6c consisted of various applications on top of SAP Basis, SAP's set of middleware programs and tools.

When SAP R/3 Enterprise was launched in 2002, all applications were built on top of the SAP Web Application Server. Extension sets were used to deliver new features and kept the core as stable as possible. The Web Application Server contained all the capabilities of SAP Basis.

The first edition of mySAP ERP was launched in 2003 and bundled previously separate products, including SAP R/3 Enterprise, SAP Stategic Enterprise Management (SEM) and extension sets. The SAP Web Application Server was wrapped into NetWeaver, which was also introduced in 2003.

A complete architecture change took place with the introduction of mySAP ERP edition 2004. R/3 Enterprise was replaced with the introduction of ERP Central Component (SAP ECC). The SAP Business Warehouse, SAP Strategic Enterprise Management and Internet Transaction Server were also merged into SAP ECC, allowing users to run them under one instance. Architectural changes were also made to support an enterprise services architecture to transition customers to a services-oriented architecture.

More than 2,300 customers are using the latest version of mySAP ERP, since it was released earlier this year, according to SAP. SAP reported a 20% growth in new ERP license deals in the second quarter of 2005.
