| However, the database offers many advantages that we can apply to the user interface without wasting much time. One of these advantages is the "default value" of columns in tables. | However, the database offers many advantages that we can apply to the user interface without wasting much time.

Besides, the developer would rather spend time on challenging problems than on boring tasks. | + | During the creation of a dataset, the developer would have to consider these default values in the user interface and preset them for the user.

| This is where JVx comes in handy. The framework recognizes the default values of columns automatically and assumes the defined values during the creation of new datasets directly in the user interface. It should be noted, however, that only constant default values are considered since function calls are always database-dependent and could contain logic. | This is where JVx comes in handy.
