App workbench Tables tab in Jitterbit App Builder

Tables is the second tab in the App Workbench. It is the second tab that relates to the data layer of your application and is where you can see a list of all the tables present in the data sources connected to the current application, the relationships between them, and add new tables or edit the existing ones.

The image below shows the Tables tab for an application with a data source currently containing three tables:

There are three panels:

In the App Data Sources panel, a dropdown menu lists all the data sources connected to the current application. The one selected by default is the primary data source.
The Tables panel shows:
- The + Table button, which allows you to add a new table to the selected data source.
- A table listing all the tables currently present in the selected data source. A search bar allows you to look up a specific table by name. Each row of the table includes these columns:
  - Name: The table name. Each table inside a data source must have a unique name.
  - Data Source: The data source where that table resides.
  - Click the pen icon to edit the table.
The Database Schema panel shows a visual representation of the relationship between your tables. In the image, each table is a node and the relationships between them (shared columns) are shown as the lines between them.

Create a table

To add a new table, follow these steps:

In the App Data Sources panel, use the dropdown to select the data source where you want to add a new table.
In the Tables panel, click + Table. The Table Definition page opens in create mode:
Use the Table panel to provide basic information about the table:
- Name: Enter a name for your new table. Inside each data source, table names must be unique.
- Data Source: This field shows which data source you're creating a table for.
- Technical Help: A text box where you can enter additional information for other app developers about what the table contains. This text is not seen by app users.
Click Save to create the new table. If you want to discard your changes and return to the Tables tab instead, click Cancel.
The new table will be created containing one column, which has the same name as the table with the addition of ID at the end. Now you can edit your new table the same way you can edit the existing ones.

Edit a table

When you create a table, you are immediately taken to the screen where you can edit it. If you want to edit an existing table, follow these steps:

In the App Data Sources panel, use the dropdown to select the data source with the table you want to edit.
In the Tables panel, locate the table you want to edit and click the pen icon. The Table Definition page will open in edit mode, where you can make your edits:
