Throughout this course you will be working on a course project involving the analysis and design for a SOA application utilizing the SOA design principles. Initially, you will perform a top-down business-level analysis concurrently as you perform a service-oriented analysis and design. The goal is to design a SOA application that fits in with the organizational needs and fits with the SOA architecture. Your process will utilize the agile strategy (meet-in-the-middle) SOA delivery strategy model from the Erl text.
Refer to the following in your Erl text for details.

Step 1: Read the following scenario.
Scenario: Because of economic pressure from a major competitor (e.g. the NetFlicks video rental company), the Reddish Box $1 video rental company has decided to form a strategic alliance with the failing Blockbooster video rental company.
Blockbooster wants to entice customers to visit an online video ordering website by providing a listing of movies that are available at Reddish Boxes in their immediate area based on the customer’s zip code or Google map location. Blockbooster hopes that if a particular movie is not available at a local Reddish Box, then the customer will order the movie from the Blockbooster website for home delivery (similar to the NetFlicks business model). Blockbooster will charge $1 dollar for each video rental, however they will include the postage and handling fee of $1.00 for mailing costs; no subscription to Blockbooster is required.
To facilitate the near real-time display of Reddish Box movies (e.g. available inventory) located within a particular zip code, Blockbooster has decided to use SOA Web Services to gather the necessary data from each independent Reddish Box based on the location. Each Reddish Box, whether located in a McDonalds or outside of a store (e.g. Walgreens), is wired for communication via the internet. The boxes already have an application that sends a XML SOAP message via the internet to local Reddish Box support offices when a box needs to be serviced by an employee (e.g. movies that need to be restocked). Reddish Box has discovered that frequent restocking of movies facilitates more rentals (e.g. more revenue from a particular box).
Forming a strategic alliance with Blockbooster is a win/win situation for both corporations because Blockbooster has agreed to pay Reddish Box 3% of gross rentals that subsequently result from the website. Reddish Box also benefits because customers are not perturbed when they reach a Reddish Box location and the movie is unavailable. The webpage is offered on wireless devices so that customers can check the inventory while driving to a particular location, although driving and browsing the web is discouraged by Reddish Box and Blockbooster.
Step 2: Develop your SOA analysis and design based on the scenario above. Your Service-Oriented Analysis Course Project must address the following:
- Define the scope of the analysis
- Identify existing automation systems
- Model candidate services using the BPM and entity model provided by the Reddish Box IT department (below). Follow the 12 steps shown in Chapter 12 and detailed in the diagram on page 399.
- Provide the various diagrams and documents shown in Chapter 12 similar to what was provided by the RailCo case study.
- Compose SOA (Identify Web Services and XML that you will need using the entity model as a guideline to define the XML)
- Design services (Define message schema types, develop an abstract service interface, apply principles of service-orientation, standardize and refine the service interface, extend the service design, and finally identify other services)
- Design the application (steps 1 – 6 on page 523)
Step 3: You paper must include:
- Each section must be clearly labeled using APA style and format
- Title page – includes the student name, date, course number and name, facilitator name, and course term.
- Course Project Contents
- Diagrams must be developed using an electronic drawing tool, MS Visio is highly recommended.
