Architecture of the Query Tools 
- SQL Studio (GUI for Microsoft Windows): When requested by the client, a connection is set up to the database instance through the ODBC interface. After this, communication can take place between the client and the database instance.
- Web SQL Studio: Calling the Web SQL Studio in the Web browser sets up a connection to the client (Web SQL service integrated into the Web server). The communication between this client and the database instance takes places through the ODBC interface (see also Architecture of the SAP DB Web Tools).
