Instructor Notes Module 7: Selecting
Solution Technologies
Introduction
Part of physical design is evaluating solution technologies. This module teaches
students how to evaluate the available technologies in order to make appropriate
choices for the business solution. Students will learn about types of solution
technologies and some factors to consider when selecting technologies from
these categories.
After completing this module, you will be able to:
!
Describe Microsoft
®
Windows
®
Distributed interNet Applications
Architecture (Windows DNA) and how it applies to an application’s
development.
!
Describe a process for selecting solution technologies for implementing the
designed solution.
!
Evaluate implementation technologies from the perspective of the solution
requirements, business considerations, enterprise architecture
considerations, and whether the technology should be reused, purchased, or
built.
!
Evaluate the technology implications of solution requirements.
!
Identify technology types and their evaluation criteria.

Activities
Activity 7.1: Determining Technology Requirements
In this activity, you will identify the technology requirements in the Ferguson
and Bardell, Inc. case study.
This activity demonstrates that business decisions drive technology decisions.
After completing this activity, students will be able to:
!
Identify the types of technologies required by a scenario that presents a
business challenge.

!
To prepare for the activity
1. Complete the activity.
Think through alternative answers that students might present during the
discussion.
2. Prepare examples from your own experience.
3. Prepare some questions to foster a class discussion.

Activity 7.2: Determine the Impact of Technology on a
Windows DNA Design
In this activity, students will identify possible implications of technology on a

Windows DNA solution.
After completing this activity, you will be able to:
!
Specify and articulate the impact of technology types upon each layer of a
Windows DNA solution.

!
To prepare for the activity
1. Complete the activity.
Think through alternative answers that students might present during the
discussion. Check your answers against the solution document.
2. Prepare examples from your own experience.
3. Prepare some questions to foster a class discussion.

Module Strategy
Use the following strategy to present this module:
!
Distributed Applications Using Windows DNA
This section introduces Windows DNA and briefly explores its components
and advantages. Your primary objective should be to get the class to see the
interlocking, interdependent nature of the various elements of the Windows
DNA architecture, and to begin to understand the advantages of writing
applications that comply with the Windows DNA framework.
!
Technology Selection Process
This is a critical section in which students learn criteria for selecting

candidate technologies. It is vital that you communicate the importance of
examining all of the criteria, not just the technical ones.
Additionally, it is critical that students recognize the implications that the
selection of technology can have on business goals, plans, and documents.
Emphasize that the technology is a tool that supports business requirements
and goals.
!
Activity 7.1: Determining Technology Requirements
The focus of this activity is fairly broad. You might want to narrow the
focus by assigning specific areas of the case study to each group of students.
You should facilitate the discussion to develop a class consensus on the
primary implications of technology requirements as stated in the Ferguson
and Bardell, Inc. case study.
!
Considerations by Technology Type
This section builds upon the concept of technology selection by examining
various considerations within each part of the Windows DNA architecture.
For some students, this section will be somewhat new; they may have never
considered the implications that their various choices of technology (such as
what operating system to select) may have on their environment.
Be prepared with examples of such implications, in addition to the examples
in the text. This section also leads into the next two modules, Module 8
(“Solution Design and the Component Object Model”) and Module 9
(“Designing Solutions with Microsoft Technologies”). The technology types
presented in this module provide the basic definitions and framework for the
specific details of Modules 8 and 9.
!
Activity 7.2: Determine the Impact of Technology on a Windows DNA
Design
In this activity, students examine each of the technology types and identify

how the technology type might impact a Windows DNA application. Use
this activity to solidify students’ understanding of the technology types
because these technology types are the basis for Module 9.
