SAP based the architecture of ECC on a three-tier client/servermodel


21/29

Presentation Server

Thepresentation serveris actually a program namedsapgui.exe usually installed on a user's workstation.

SAPGUI accepts input from the user in the form ofkeystrokes, mouse-clicks, and function keys, and sendsthese requests to the application server to be processed.

The application server sends the results back to theSAPGUI which then formats the output for display to theuser.


22/29

Application Server

An application serveris a set of executables thatcollectively interpret the ABAP/4 programs andmanage the input and output for them.

ABAP/4 programs run on the application server.

If ABAP/4 program requests information from thedatabase, the application server will format therequest and send it to the database server.


23/29

Database Server

The database serveris a set of executables that accept databaserequests from the application server, and pass the informationback to the application server.
