Technical System Landscape

Database Tools

You can use different database tools to manage a database, and to change data in a database.

Database Tool

Applications

Applications use databases to store data and use interfaces to access databases. More information: Interfaces

This graphic is explained in the accompanying text.

Application with an Interface to an SAP MaxDB Database

Interfaces Between SAP Systems and SAP MaxDB
SAP System	SQL Interface to SAP MaxDB
SAP NetWeaver AS	SAP MaxDB SQLDBC
SAP NetWeaver BI	SAP MaxDB SQLDBC
SAP NetWeaver EP	SAP MaxDB JDBC
SAP NetWeaver MI (Clients)	SAP MaxDB JDBC
SAP NetWeaver MDM	SAP MaxDB JDBC
SAP NetWeaver XI	SAP MaxDB JDBC

Interfaces Between an SAP AS System and SAP MaxDB Databases

Communication Server

Database tools, interfaces and the database can be located on different computers in a network. To access a database located on a remote computer, the SAP MaxDB X Server (communication server) must be running on the remote computer. Note that the JDBC interface needs the X Server even if it is installed on the same computer as the database. More information: Network Communication and X Server documentation

In SAP systems, you can encrypt the data transfer between database tools, or the interface, and X server using SSL. More information: Database Administration, Encryption

How an SAP MaxDB Database is Accessed from Remote Computers

Example

There are two SAP MaxDB databases on two different computers in the LAN 2 network. There is a SAP MaxDB X Server (communication server) running on each of the computers. Using these X Servers, SAP systems from the networks LAN 1 and LAN 3 access the SAP MaxDB databases in LAN 2.

From LAN 1, an SAP NetWeaver AS system accesses a SAP MaxDB database in LAN 2 by means of SAProuter:

For SQL statements, the AS system uses the SAP MaxDB SQLDBC interface.
For administration commands, the AS system uses the SAP RFC library and the SAP MaxDB DBM RFC server.

SAProuter does not have to be used for communication. All connections can be encrypted with SSL.

From LAN 3, an SAP NetWeaver EP system accesses a SAP MaxDB database in LAN 2:

For SQL statements, the EP system uses the SAP MaxDB JDBC interface.
For administration commands, the EP system uses the SAP RFC library and the SAP MaxDB DBM RFC server.
