These actions can be done in several ways:
1. By clicking on the corresponding buttons (Add
, Delete
, Edit
).
2. By pressing the underlined key in the name of the buttons (for Add
we press the 'A' key, ...).
3. By using shortcuts: Add - Ctrl+Ins, Edit - Ctrl+F8, Delete - Ctrl+Del
There are some cases where these actions are not allowed in order to preserve the integrity of
the data (e.g. deleting a book from the inventory if it has been loaned at least once).
Adding
Adding is used to add rows of data into documents or lists (e.g. entering book details)
Fill in the corresponding fields and click on the Save
button to complete the adding action.
Deleting
This action is easily done by selecting the row to delete and clicking on the Delete
button.
Editing
Editing is done by selecting the row to edit and clicking on the Edit
button.
It is necessary to click on the Save
button to save the changes in the database. In order to edit
fields correctly, it is necessary to go through all the fields of the selected row (even if all the fields
are not being updated), since the button Save
is enabled only at that moment.
