Architecture of the R/3 System Chapter 14
2
Problems of Enterprise-Wide Computing Slow response time during peak traffic loads Different time zones, systems, upgrades Heterogeneous database problem Multiple platforms
3
R/3 and Enterprise Computing Development of “middleware” enables portability across platforms –Technologies include: Db replication, messaging, XML, remote procedures R/3 supports: –TCP/IP –RFC –SQL & ODBC –OLE, MAPI, EDI
4
R/3 Server Installations 3-tier C/S preferred –Homogeneous - same OS on one or more platforms –Heterogeneous - a variety of platforms ex. UNIX, NT, Windows on application server UNIX with Oracle, Informix, DB2 on db server –R/3 solves the distributed multiple heterogeneous platform problem with “middleware”
5
Benefits of Multiple Application Servers An alternate server can be automatically selected if one is unavailable “Load balancing” of clients to least busy server Can optimize queries and reduce load on db server to improve response time Because it is scalable, servers can be added as more processing capability is needed
6
C/S Scenarios Centralized host computer performs all tasks including db, applications, and presentation 2-tier C/S - db server is separate from “thick client” which processes apps and presentation 3-tier C/S - separate systems for db, apps, and presentation (preferred by R/3) N-tier C/S – extension using servers on Internet
7
SAP R/3 Basis System
8
R/3 Middleware Transfer Protocols Front-end (presentation tier) –R/3 GUI uses resident OS resources to cut flow of data to 1-2 KB –whole screens are not passed but only logical control information and user inputs DB interface (between app and db servers) –SAP SQL within ABAP/4 environment –then translates queries into “native” SQL
9
More Middleware Functions Interprogram communications –synchronous vs. asynchronous Synchronous uses CPI-C, from IBM in the late ’80s –RFC/RPC libraries and DLLs to call R/3 functions/modules –SAP is closely aligned with COM from MS Transaction management –ALE -distributes db availability to several sites routes data, maintains security creates IDOC master which contains info about the data SAP experimenting with XML for internal messaging
10
Application Linking & Enabling (ALE) Allows users to set up applications and databases at distributed locations Not only routes data, but knows what data are needed in given situations; “intelligent middleware” –ALE checks for consistency of data, updates –uses IDOCS to send message between loosely coupled systems, with possibly dif. R/3 ver. –Asynchronous RFC means if system is down on target it will retry again
11
R/3 Distribution Scenarios Initially, R/3 was designed with one centralized db in mind (from late ’80s) ALE technology was developed to enable different integration scenarios –Contained in Business Blueprint Centralized, integrated DB and application server Centralized by module on servers Completely decentralized R/3 with central db “Next Generation” architecture

NetWeaver Adoption SAP anticipates that NetWeaver will redefine the company in a global manner –About 3000 of more than 24,000 potential companies have put some portion of NetWeaver into play –Early stage of maturity –IBM and MicroSoft supporting NetWeaver –SAP committed heavily to grow this in 2004 and 2005
16
NetWeaver Components SAP NetWeaver 2004 Synchronized Release as a single package –SAP WAS 6.4 –SAP EP 6.0 –SAP XI 3.0 –SAP BW 3.5 –SAP MI 2.5 (SAP MDM limited usage at this point) All sold and shipped together and can be installed in one procedure –Still possible to run individually –Ramp up was April 2004

Growing Importance of CRM Based on a recent GartnerGroup survey (Aug 2000) on customer service e-tailing sites, there are many potential areas for improvements. Some are simple; others require significant investments in people, processes and technology. Here are the top-10 pitfalls: 1. Requiring a password to access customer service 2. Lack of a customer service tab 3. Lack of search engines for general customer service 4. Lack of a site map 5. Lack of internationalization 6. Lack of agent support for new channels 7. Lack of working channels 8. Lack of good customer service on the phone 9. Lack of coordination between click and brick 10. Requiring software download for access
