| − | We want to connect to a database. In Scout terms, the client might want to fill a table with data from the database. It calls a service on the server which provides the desired data. That service in turn has to get the data from somewhere. In this case, it sends a SQL statement to yet another service, the '''SQL service'''. This service will handle connecting to the database and the rest.

| − | Support for [http://www.postgresql.org/ PostgreSQL] and [http://www.oracle.com/de/products/database/index.html Oracle] is trivial to add

| − | | + | |
| − | Go to the server node and open the tree, drill down to ''Sql Services'' below ''Common Services'' and right-click on it in order to open the wizard to create a new SQL service.

Switch to the Java Perspective, double-click on the server project, open the plugin.xml file, go to the ''Dependencies'' tab and add the plug-in ''org.eclipse.scout.rt.jdbc.derby'' to the ''Required Plug-Ins''. If the Super Type still does not appear, make sure that the ''derby.jar'' is in the lib folder of the Java installation. You can get this library directly from [http://db.apache.org/derby/ Apache Derby].}}

| − | | + | |
| − | Adjust the '''settings''' in your ''DerbySqlService'' by editing the '''Jdbc Mapping Name'''. It should point to the folder where you unzipped the DerbyDb to. That's the example database you downloaded {{ScoutLink|Tutorial|3.7/Minicrm/Get example database|at the beginning of this tutorial}}.

| − | Also make sure you have the right '''Jdbc Driver Name''' set.
