ERP software combines data from various business functions into a single system with a unified database and simplified infrastructure. SAP R/3 is a major ERP software from SAP. The SAP GUI runs on user workstations and provides an interface for submitting transactions. An application server processes requests and communicates with the database server which accesses the relational database. SAP consists of key business modules like financials, human resources, materials management and more. Common transaction codes in SAP include SE11 for data dictionary, SE30 for runtime analysis and SM30 for table maintenance.

function keys, and sends these requests to
the application server to be processed.

11.  An application server is a set of executables
that collectively interpret the ABAP/4
programs and manage the input and output
for them.
 If ABAP/4 program requests information from
the database, the application server will
format the request and send it to the
database server.

12.  The database server is a set of executables
that accept database requests from the
application server.
 These requests are passed on to the RDBMS

database server, which then passes the
information back to the application server.
