SAP's products focus on Enterprise Resource Planning (ERP), which it helped to pioneer. The company's main product is SAP ERP. The name of its predecessor, SAP R/3 gives a clue to its functionality: the "R" stands for realtime (even though it is not a realtime solution), the number 3 relates to a 3 tier client-server architecture (database layer, application layer and presentation layer) 3-tier architecture: database, application server and client ( usually a SAP GUI ). R/2, which ran on a Mainframe architecture, was the first SAP version.
SAP ERP is the one of five major enterprise applications that makes up SAP's Business Suite. The four other applications are:
- Customer Relationship Management (CRM) - helps companies acquire and retain customers, gain deep marketing and customer insight, and align organization on customer-focused strategies
- Product Lifecycle Management (PLM) - helps manufacturers with a single source of all product-related information necessary for collaborating with business partners and supporting product lines
- Supply Chain Management (SCM)- helps companies enhance operational flexibility across global enterprises and provide real-time visibility for customers and suppliers. Supplier Relationship Management (SRM) - customers can collaborate closely with suppliers and integrate sourcing processes with applications throughout the enterprise to enhance transparency and lower costs
Other major product offerings include: the NetWeaver platform, Governance, Risk and Compliance (GRC) solutions, Duet (joint offering with Microsoft), Performance Management solutions and RFID. SAP offers a systematic approach to enterprise SOA, which is the technical standard that enables various enterprise software applications to exchange data effectively. Through enterprise SOA, SAP is focusing on enabling more flexible business processes as well as creating technical connections between IT systems and building a common language for business.
While its original products were typically used by Fortune 500 companies, SAP is now also actively targeting small and medium sized enterprises (SME) with its SAP Business One and SAP Business All - in - One. On September 19th, 2007 SAP announced a new product named SAP Business ByDesign complementing its portfolio for SME. SAP Business ByDesign was known under the code name "A1S" before. SAP officials say there are over 100,600 SAP installations serving more than 41,200 companies in more than 25 industries in more than 120 countries.
