Software Service Engineering

Software Service Engineering (Master Degree in Computer Science and Networking - a.y. 2011/2012)
Instructor: Antonio Brogi

News. To try facilitating students that are completing their degree, a new exam date has been introduced in March. To try facilitating the organization of all students, the other dates are anticipated at the end of this page, too. All dates have been scheduled so as to align them with the graduation deadlines. All exams are open to all students.
Objectives. The overall objective of the course is to introduce some of the main aspects in the design, analysis, and development of software services. After introducing the core standards of Web services, the course focuses on service composition as one of the key aspects of service-oriented architectures, and the use of workflow languages supporting the specification and the execution of business processes is illustrated. The role of business process analysis is discussed, and some examples of modelling and analyses of business processes are illustrated. The advantages of enhanced service descriptions including policies and behavioural informaton, and the role of service agreements are also discussed. Finally, some of the currently emerging technologies are introduced. The course includes a “hands-on” lab devoted to experiment the design, analysis, development and deployment of simple Web services.

The examination will consist of two parts:

A discussion of the project, in which each student will also be asked to make a short demo and to implement a small change in the project
Questions on the topics of the syllabus.
