This course focus on the need for systems interoperability and how Web services, an umbrella concept for different cross-platform solutions based on Web standards, attempt to overcome the many challenges that distributed information systems have addressed in various ways (but not always successfully) in the past. By the end of the course, students will have learned the relevant concepts related to the nature, characteristics and types of Web Services and acquired some experience in consuming, designing, constructing and maintaining services located at the web.

Teaching methodology

The teaching of the course is structured in lecture sessions and laboratory sessions.

Lecture sessions: 2 hours per week.
The instructors can present some of the course content using slides or other material available at Atenea. There will be also sessions in which students will be required to prepare on their own and present to the class a certain topic.

Laboratory sessions: 2 hours per week.
During the first 9 weeks of the course, and after a brief introduction, the students will be required to complete a certain number of tasks using the computer in accordance with a work plan.
During the remaining weeks of the course, the students, in groups of 3-4, will design and implement a web service project. The lab sessions will be used to work in the project, discuss and fix doubts and problems, plan and manage goals, and present results.
