Begin Adding Action Diagram Statements

Follow these steps:

1. In the ADD GOLFER action diagram, select the blank line directly beneath ENTITY ACTIONS: as indicated in the following diagram:

   

   Here are some tips on adding action diagram statements:

   • When adding an action diagram statement, you always select the blank line or existing action diagram statement that you want to add the new statement being added. If is directly above a statement between two existing statements, select the statement that you want to add the new statement after. The Toolset will then insert the new statement directly below of the highlighted statement and above any subsequent statements.
   • The Toolset makes different options available to you depending on what you have selected. In the previous example, had we not selected the blank line and instead selected ENTITY ACTIONS: at the top of the blank line, the Toolset would not allow us to add any statements. It would, however, allow us to add an entity view to our entity action views. If we had selected the bottom of the bracket running down the far left side of the action diagram that indicates the end of the action diagram, the Toolset would also not have allowed us to add any statements. You cannot add statements outside of the action diagram.
   • To add a new action diagram statement, with a few exceptions, the entire statement that you are trying to add the new statement beneath has to be highlighted. If only a portion of the statement is highlighted, the Toolset thinks you are trying to change only the highlighted portion, instead of adding a new statement altogether. The easiest way to highlight the entire statement is to select the first word in the statement.
   • Finally, if you want to delete a statement, select the statement and then press the Delete key on your keyboard or select the Delete icon on the Tool Bar. You can delete several statements at the same time. If the statements are all together, you can click-and-drag the cursor down across the first word in each statement, highlighting all of them at once, and then select the Delete key or the Delete icon. If the statements are scattered throughout the diagram, you can select the first one, and then hold down the Ctrl key while selecting the others. Once they are all highlighted, select the Delete key or the Delete icon.
2. With the blank line highlighted, select Edit from the Menu Bar, then Add Statement from the drop-down menu, and then select Create… from the choice of statements. This opens the Add Statement dialog as shown in the following example:

   

   When adding statements, you build the statement in the upper panel by selecting options presented to you in the lower panel. When you are finished building the statement, you select the Add push button to add it to the action diagram. The Add push button will be disabled (as in the previous example) until you have a syntactically correct statement.

   When adding Create, Read, Update, Delete, or Read Each statements, the options it would normally show you in the bottom panel are your Entity Action views. Entity Action views are used to manipulate the information in the database. Since we have not yet created any views, it is not showing us any views. However, we can perform view maintenance from here.
