The Problem
The application development process using Oracle Designer and Headstart can best be described as a matrix.
It consists of 3 logical layers: the Data Layer, the Business Logic Layer, and the Presentation Layer.
For each of these layers, activities are performed during the Analysis Phase and the Design and Implementation Phase.
The remainder of this workshop is organized around this development approach matrix.
