Now, all four attributes of the Tip object have been extracted, and we then need to store the object in a database. We need to insert a new step after Extract Description, and then configure this to use the Store in Database action. Also, we need to add a database to the project.

To add a database to the project, we must create a database mapping to it. To do this, you right click the database to add in the Database View as shown below. We want to add the Development Database to our "8.2.0" Project, so right-click that, and click "Add to Project..." and select the "8.2.0" project. It is recommended to use the mapping name suggested in the pop-up dialog unless you know what you are doing (read about database names here ). This creates a database mapping in the project which maps to the database. For more general information on database mappings, look here .

Inserting the Store in Database Step

Make sure that the End step of the robot (the last step) is selected, if it is not then left click it. Now, click on button in the toolbar to insert a new step before the selected step. Select the Store in Database action from the Action dropdown of the new Unnamed step.

The Store in Database step configures itself and selects the database mapping we created and the "tip" variable, since it is the only variable we use. Because the database mapping refers to the Development Database, it is also ensured that this database is running (it is auto-started if required). Auto-starting is only supported for the Development Database, so if you use a different database, you must make sure that the database is running.

Finally, we must select a key for the value being stored. A key is a unique identifier for the stored value, and is used to check if the value already exists in the database. The key is also used by the actions "Find in Database", and "Delete from Database". The default value for the Key property is Key Defined in the Type. This means that the key is automatically calculated from the attributes in the type which are configured to be Part of Database Key.

Notice that the Store in Database step has a red error icon, indicating that the step is invalid. If you move the mouse over the error icon, a popup will inform you of the problem. In this case, the error is that we can't use "Key Defined in Type" because no attributes are marked as "Part of Database Key". To fix this, we need to go back and modify the type.
