Instructor Notes Module 10: Completing Physical Design

Instructor Notes Module 10: Completing Physical Design Introduction This model teaches students to complete the last two steps of physical design: rationalization and specification. Students learn how to develop a packaging and deployment strategy and how to create deployment models. After completing this module, students will be able to: ! Complete the rationalization step of physical design. ! Derive a physical design from a logical design. ! Describe the deliverables of a physical design specification. ! Describe a component specification. Materials and Preparation This section provides you with the materials and preparation needed to teach this module. Materials To teach this module, you need the following materials: ! Microsoft ® PowerPoint ® file P10_1608a.ppt ! Module 10, “Completing Physical Design” ! Activity 10.1, “Creating and Distributing Preliminary Components” ! Activity 10.2, “Refining Preliminary Distribution for Performance” ! Activity 10.3, “Factors Impacting the Programming Model” Preparation To prepare for this module, you should: ! Read all the materials for this module. ! Complete the activities. Presentation: 75 Minutes Activity: 60 Minutes 2 Instructor Notes Module 10: Completing Physical Design Activities Activity 10.1: Creating and Distributing Preliminary Components In this activity, students will place candidate components into service layers assigned in a previous activity. After completing this activity, students will be able to: ! Create a preliminary component topology by distributing preliminary components across the network topology. ! To prepare for the activity 1. In case some students do not have their copies, prepare extra copies of the Future Network Topology from the Ferguson and Bardell, Inc. case study, the business object model created in Module 5, and the service layer topology created in Module 6. 2. Complete the activity yourself. 3. Prepare some questions to foster a class discussion. Activity 10.2: Refining Preliminary Distribution for Performance In this activity, students will reorganize their candidate components to account for additional constraints or requirements. After completing this activity, students will be able to: ! Modify a component topology to meet other requirements. ! To prepare for the activity 1. Complete the activity yourself. Be prepared with examples to use as discussion starters in case any groups get stuck on the last question. 2. Prepare some questions to foster a class discussion. Instructor Notes Module 10: Completing Physical Design 3 Activity 10.3: Factors Impacting the Programming Model In this exercise, based on the course material preceding this activity, students will take part in a class discussion to identify what has the greatest impact on determining a programming model. After completing this activity, students will be able to: ! Articulate some of the factors that impact how a team chooses and implements a programming model. ! To prepare for the activity 1. Think through the possible class discussion. Prepare starter examples to aid the class during brainstorming. 2. Be sure you have enough flip-chart paper and working markers for the discussion. 3. Prepare examples from your own experience. 4. Prepare some questions to foster a class discussion. 4 Instructor Notes Module 10: Completing Physical Design Module Strategy Use the following strategy to present this module: ! Physical Design Rationalization The focus of the rationalization step is on designing services-based components and developing a distribution strategy for those components. Continue to emphasize the iterative nature of design, including the rationalization step. By this point in the course, some students will be struggling with the multitude of new terms and concepts they have learned. Keep them moving forward, but be sensitive to the “brain fatigue” they may be experiencing. As a motivating factor, remind them that they are only two steps from completing their physical design. ! Activity 10.1: Creating and Distributing Preliminary Components This activity is in the section. The students will develop preliminary components and distribute them based on the preliminary topology they developed. ! Activity 10.2: Refining Preliminary Distribution for Performance Students should attempt to optimize the component distribution to achieve maximum performance. ! Physical Design Specification In this section, students will learn about the final step in physical design: specification, which includes determining the programming model and documenting the component interfaces. Emphasize the importance of completing this step so that the development team has a complete specification from which to work. A well-conceived programming model helps ensure standards throughout the development project, and as a result, will actually save time later in the development process. ! Activity 10.3: Factors Impacting the Programming Model In this discussion, you can gauge students understanding of both the programming model and of the culmination of physical design. . discussion. 4 Instructor Notes Module 10: Completing Physical Design Module Strategy Use the following strategy to present this module: !
