Subject Title
Web Services

Subject Description

Web Services are applications with two characteristics: First, a web service publishes an application programming interface (API) for the functionality it makes available to external callers. Second, a web service is accessed over a network by using the hypertext transfer protocol (HTTP). Web services enable interoperablility between software systems, and are the foundation for a modern service oriented architecture (SOA).

This course is a thorough introduction to web services. Students will learn to create and consume web services, as well as the web services standards, technologies, platforms, and development tools.

Credit Status
1 credit (3 units)
Professional Option for BSD -­ Bachelor of Technology (Software Development)

Learning Outcomes
Upon successful completion of this subject the student will be able to:

  • Understand and describe the principles of service oriented architecture
  • Understand and describe the standards and technologies of modern web services implementations
  • Effectively use market-leading development tools to create and consume web services
  • Identify and select the appropriate framework components in the creation of web service solutions
  • Apply object-oriented programming principles to the creation of web service solutions
  • Analyze the requirements of a medium-difficulty programming task, and create software that meets the requirements
  • For a given specification, determine the appropriate web services style and design
  • Compare service oriented architecture with other kinds of design principles

Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: http://www.senecapolytechnic.ca/about/policies/academic-integrity-policy.html Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website http://open2.senecac.on.ca/sites/academic-integrity/for-students to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.

Discrimination/Harassment
All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment. Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated. Information and assistance are available from the Student Conduct Office at student.conduct@senecapolytechnic.ca.

Accommodation for Students with Disabilities
The College will provide reasonable accommodation to students with disabilities in order to promote academic success. If you require accommodation, contact the Counselling and Accessibility Services Office at ext. 22900 to initiate the process for documenting, assessing and implementing your individual accommodation needs.

Camera Use and Recordings - Synchronous (Live) Classes
Synchronous (live) classes may be delivered in person, in a Flexible Learning space, or online through a Seneca web conferencing platform such as MS Teams or Zoom. Flexible Learning spaces are equipped with cameras, microphones, monitors and speakers that capture and stream instructor and student interactions, providing an in-person experience for students choosing to study online.

Students joining a live class online may be required to have a working camera in order to participate, or for certain activities (e.g. group work, assessments), and high-speed broadband access (e.g. Cable, DSL) is highly recommended. In the event students encounter circumstances that impact their ability to join the platform with their camera on, they should reach out to the professor to discuss. Live classes may be recorded and made available to students to support access to course content and promote student learning and success.

By attending live classes, students are consenting to the collection and use of their personal information for the purposes of administering the class and associated coursework. To learn more about Seneca's privacy practices, visit Privacy Notice.
