The VB Enterprise Development Model

The idea of a conceptual design, a logical design, and a physical design, as noted in the preceding section, belongs to VB5 and Visual Studio 5 documentation; here it is referred to as the VB Enterprise Development Model.

Brief descriptions of the three design phases follow:

  • Conceptual design regards the system from the point of view of the proposed system's users.
  • Logical design identifies the business objects and underlying services required by the conceptual design.
  • Physical design identifies the specific implementations of the logical design, including the specific hardware and software solutions.

The following sections of this lesson deal with them more extensively.

  1. The Conceptual Design
  2. Deriving the Logical Design From the Conceptual Design
  3. Deriving the Physical Design From the Logical Design
