MILESTONE 9 – APPLICATION ARCHITECTURE

Synopsis

J

ust as we modeled business requirements during systems analysis, we should model technology architecture and requirements during systems design. The models serve as blueprints for system design, prototyping and construction.

In this milestone you will prepare a Physical Data Flow Diagram. Physical data flow diagrams model the technical and human design decisions to be implemented as part of an information system. They communicate technical and other design constraints to those who will actually implement the system—in other words, they serve as a technical blueprint for the implementation.

Objectives

After completing this milestone, you should be able to:

Draw physical data flow diagrams for an information system’s architecture and processes.

Prerequisites

Before starting this milestone the following topics should be covered:

1. Systems design - Chapter 12 2. Application architecture and physical DFDs – Chapter 13

Assignment

The goal of this project is to produce a high-level general design that can serve as an application architecture for the system and a general design for the processes that make up the system.

Activities

1. Prepare the physical DFD based on the narrative provided in Exhibit 9.1. Make assumptions where necessary.

Deliverable format and software to be used are according to your instructor’s specifications. Deliverables should be neatly packaged in a binder, separated with a tab divider labeled “Milestone 9” and accompanied with a Milestone Evaluation Sheet.
