How to Enhance Your Applications
Vision lets you take an adaptive approach toward developing applications. You can begin by using Vision to develop simple applications. As your information needs and your ability to use Vision and Ingres tools increase, you can gradually enhance your applications.
Develop your applications in these stages:
Create an application using the frames, forms, and queries that Vision generates.
Customize your queries with Vision's Visual Query Editor.
Modify the forms that Vision creates.
Specify more complex queries by using Vision's advanced features and including 4GL statements.
Add frames that work with other Ingres tools, such as Report-By-Forms.
Modify the code that Vision generates for a specific frame.
Include User frames and procedures.
These development stages are discussed throughout this guide. Depending on your familiarity with Vision and the other Ingres tools, you can use as few or as many of them as you need to create applications with Vision.
Note:  It is important to test your application frequently while you were building it.
