CSC 450 - Web Services

Concepts, theories, and techniques for Web services. This course examines architectures for Web applications based on the classical publish, find, and bind triangle. It considers the description, discovery, and engagement of Web services. It emphasizes Web service composition. Key topics include semantics, transactions, processes, agents, quality of service, and compliance.

• Lecture: 3 hours

Course Outcomes:

1. Design and launch web services and use services published by others
2. Build reactive programming systems
3. Develop actor-based distributed service systems
4. Conceptually model web services and formulate specifications of them in the Resource Description Framework (RDF) and the Web Ontology Language (OWL)
5. Apply principles of distributed transactions, business processes, business protocols, rules, and agents to specify, monitor, and manage the behavior of composed services
6. Understand and apply concepts of communication and organizational modeling for realizing decentralized service-oriented systems
7. Evaluate emerging and proposed standards for service architectures
8. Specify application protocols to describe how services interact with each other
9. Understand and apply modeling methods geared toward asynchronous interaction
