Overview
 Motivation
 Course Module Approach
 Course Modules
 1 (Consuming a Web Service)
 2 (Building and Deploying a Web Service)
 3 (Web Service Applications)
 Conclusion
Motivation
 Global service-oriented middleware market will grow to
at least $8.2 billion by 2016, according to a
WinterGreen Report1
 Crucial for undergraduate CS/SE students to learn
about web services and service-oriented computing
 Students need repeated exposure to SOP concepts at
different degrees of depth

Student Goals
 Explain the motivation for learning about serviceoriented programming (SOP)
 Describe the issues and concepts underlying SOP
 Solve problems using SOP techniques
 Gain hands-on experience with SOP
Abstractions: Evolution

Rosa, QUT
Object- and Service-Orientation
 Steps in solving a complex problem
 Abstraction
 Decomposes problem into sub-problems
 Solves each sub-problem and composes overall solution
 Object-orientation
 Describes an abstraction using objects
 Objects help to model problem and develop the solution
 Service-orientation
 Describes an abstraction using services
 Services help to model problem and develop the solution
 Developed service can be used to develop new services
Service Oriented Programming
 Basic idea
 Wrap up a software system as a set of services,
accessible via the Internet
 Use services as the building blocks to develop
applications
 Standardize the way of describing, querying, and calling a
service to deal with interoperability issues
Service Oriented Architecture
 A meta-architectural style that supports loosely coupled
services to enable business flexibility in an
interoperable manner
 SOA requires the following
 All functions are defined as services
 All services are independent of each other
 Service interfaces are invocable
Teaching SOP via Course Modules
 Important to incorporate SOP into the curriculum early
 Make SOP materials to instructors as course modules
 A course module is a well-defined, self-contained unit of
instruction that may be incorporated, either as-is or with minor
modifications, within one or more courses offered in diverse
disciplines
 Course modules have become an excellent vehicle for handling
curricular changes quickly
 Vertical integration into the curriculum via repeated
exposure to SOP at different depths
 Three course modules

Three Course Modules
 Course module 1
 Introduces SOP into a standard second programming
course, e.g., CS2
 Course module 2
 Presents SOP as a programming paradigm in a mid-level
course, e.g., Concepts of Programming Languages
 Course module 3
 Applies SOP to software design and development in a
senior-level course, e.g., Distributed and Concurrent
Software Systems
Course Module 1
 Targets freshmen computing students
 Lecture slides provide a brief overview of serviceoriented architecture, web service standards, and
fundamental principles of SOP methodology
 Sample questions test materials covered by slides
 Demo showcases development of an application using
web services
 Lab provides step-by-step instructions for calling a web
service
Course Module 2
 Targets mid-level students (sophomores or juniors)
 Lecture slides cover topics including service-orientation,
service-oriented architecture, service description, discovery,
invocation, and composition
 Sample questions test the material covered by slides
 Demo showcases the development of a web service and an
application using web services
 Lab provides step-by-step instructions for developing a web
service and an application by calling a web service
Course Module 3
 Targets senior students
 Lecture slides focus on the architecture, design, and
implementation of enterprise-critical software systems
 Sample questions test the materials covered by slides
 Project asks students to develop an SOP application
reflecting a real-world scenario
Concluding Remarks
Current Status
 All modules have been developed
and tested
 All modules at RIT
 Module 1 at Howard
 Module 1 and 3 at SUNY Oswego
 Initial assessment and revision

Modules and assessment at all
three institutions in 2013-14
 Improvements being pursued

In modules and in assignments
