Next, he needs to create two columns: actor_id and series_id. By selecting the table name and clicking on it, Louis can enter the text he wants. Louis must first right-click on any free area of the diagram window and choose “Create new table”. After that, he will be able to link the Actor and Series tables. Since all the relationships in his database are created through dictionary tables, he needs to add another table like this and create the keys. Now he wants to link the loaded table containing information about the TV series with the already existing table with the actors’ names. In one of our previous articles, we talked about how he was able to add a new table to his database using the Data Transfer feature. Let’s take a look at adding new elements to a diagram using our old friend Louis’ problem as an example. Using it you can add or change metadata in the existing table or create a new table with the necessary parameters. The context menu provides great opportunities for editing your scheme. Enter a new text and press Enter or click anywhere else in the diagram window to apply the changes. To change the column’s name, select it with one left click and then click on it again (just like you do with folders on your hard drive). For your convenience, you can close this tab and then open it again using the corresponding button on the bottom toolbar. In the Properties tab on the right side of the diagram window, you can change data types and other parameters. If you want to edit some metadata in your table, you will need to choose the desired column. ![]() When you switch to this mode, you will see a black border around your diagram. Open the diagram and click the Edit Mode button on the bottom toolbar. In addition, you can quickly alter some metadata or even create new tables without opening the Properties tab. When you design a database schema using a diagram, you immediately see the impact of your changes on the tables and the relationships between them. Today we want to tell you about doing it through ERD. Through ERD (only for DBeaver Enterprise and Ultimate Editions).We call the process of creating a database based on a pre-designed schema forward engineering. But ERD can be used not only to view and navigate through data but also to directly make changes to the database. ![]() In our previous article, we talked about two ways how to use diagrams with DBeaver.
