GUI Builder for LDA and PCE
General steps in GUI generation:
1) After loading an LDA Model into the Interface Builder, the user can begin to define standard GUI attributes to screens, field types, specific lines, and individual data items. Data items that are dictionary items with validation logic are automatically generated with a presentation type of Check Box, Radio Button or Combo List box depending upon the number of validation values.
2) Once GUI standards are defined a new LDA model is produced containing the GUI records. The generation can be for a single screen, selected screens or for all screens based on the model loaded in step 1. The GUI attributes are saved from one session to another. In this way, as you determine what the best standards are for your system, those standards can be applied to other specifications.
The evolutionary approach:
Using the evolutionary approach in GUI development can help determine the best presentation type (listbox, buttons etc) to apply to a data item. This will take experimentation. A suggested approach is to take a few screens (5-10) and begin to define GUI standards. Several iterations of GUI generations may take place to "learn" the best GUI standards to use. As the GUI attributes begin to become consistent, standards defined for one batch can be applied to subsequent batches automatically.
If GUI standards are changed in the future, all screens could be repainted quickly and consistently by applying the Interface Builder to the entire specification.
