Summary
VFW030 – Create a Prototype
Important Observations
- Due to time limitations, the prototyping section of these exercises is brief. When creating your own application prototype, this is a crucial step which may well determine whether your project gains acceptance or not.
- A well thought out prototype will clearly communicate what the finished application will look like and what it will do.
- A prototype should always be reviewed with the end user(s) in detail and signed off. With Visual LANSA Frameworks the prototype is completely re-used in the final application.
- To create a new application prototype with the Visual LANSA Framework, you simply set the application properties. You do not have to write any code.
- You can create application objects manually and you can create or extend an application using the Instant Prototyping Assistant.
- Applications can contain many business objects. A business object is the thing an end user works with, within an application.
- Filters enable end users to search for business objects.
- Command Handlers enable the end user to carry out business processes on business objects.
- A business object may have many command handlers.
Tips & Techniques
- Enhance the appearance of your prototype filters and command handlers using the images palette.
- The business object properties dialog enables the developer to refine the definition of the application, business object and its filters and command handlers.
