The anatomy of SAP R/3 is as follows, (1)SAP presentation server, (2)SAP application server and (3)SAP database server. Presentation server The presentation server is actually a program named sapgui. exe. It is actually installed on a users workstation. To start it, the user double-clicks on an icon on the desktop or chooses a menu path. When started, the presentation server displays the R/3 menus within a window. This window is commonly cognise as the SAPGUI or the user interface. The interface accepts input from the user in the form of keystrokes, mouse clicks, and fit keys, and sends these requests to the application server to be processed. The server sends the results fundament to the SAPGUI which then formats the output for display to the user. Application server An application se rver is a set of executables that collectively interpret the ABAP/4 programs and manage the input and output for them. When an application server is started, these executables all start at the same time.When an application server is stopped, they all shut down together. The act of processes that start up when you bring up application server is defined in a single configuration file called the application server profile. Each application server has a profile that specifies its characteristics when it starts up and while it is running. For example, an application server profile specifies. ?Number of processes and their types. ?Amount of memory apiece process may use. ?Length of time a user is inactive before being mechanically logged off. Database serverThe database server is a set of executables that accept database requests from the application server. These requests are passed on to the RDBMS (relation database management dodging).

There is usually a separate computer dedicated to house the database server, and the RDBMS may run on to computer also, or may be installed on its own computer. Defining an R/3 systemThe simplest definition of an R/3 system is one database. In one R/3 system, in that respect is only one database. To expand the definition, R/3 is considered to be all of the components attached to that one database. maven R/3 system consists of one database server accessing a single database, one or more application server and one or more presentation servers. By definition, it is all of the components attached to one database. During an implementation, there is usually one system (or one database) assigned to development, one or more systems designated for exam and one assigned to production.The term R/3 system landscape denotes a description of the n umber of systems within an SAP installation and how they are designated, such as development, test, or production.
