This course focuses on service-oriented architectural model and the service-orientation design paradigm. It will describe Service Oriented Architecture (SOA) concepts and principles, as well as quality considerations for developing modern software systems from a technical and organizational perspective.

Specifically, the course will cover principles of SOA design and SOA design patterns. Furthermore, as SOA involves more than technology, additional topics will include the impact of SOA on culture, organization, and governance.

The aim of this course is to establish a strong understanding of the concepts needed to have an effective working knowledge of SOA methodologies, and SOA systems design.

Teaching methodology

The course will be tackled by lectures, students participation and classes of problems, although the distribution in both types does not follow any regular weekly pattern.

Some of the course contents are presented by teachers but others are not presented in class. However, they must be privately studied by students in their own time. These contents are also obligatory - the only difference is the way in which they are studied. Teachers will indicate which contents should be studied at each juncture of the course, and the teaching resources that may be employed.

The classes of problems put into practice what is learnt during the course (which includes both contents presented in class and those learnt by students in their private study). Sometimes, students will be required to either have wholly or partially solved problems before the class. The problem and possible solutions will then be discussed in class. On other occasions, the problem will be set and solved in class. It is crucial for the correct development of the course that the students prepare their solutions to the exercises that teachers propose.

Evaluation methodology

The evaluation method will be based on:

Final grade: 35% Control1+ 30% Control2 + 20%Seminar + 15% Participation

Control1 and Control 2 refer to previously scheduled exams (performed during the normal sessions of the course)
Control1 will include contents 1-to 5
Control2 will include content 6

Seminar refers to the presentation of a topic related to SOA challenges that will be selected by the student and prepared through the course. The teacher will schedule the seminar at the end of the course activities. Each student is assessed on the individual presentations.

Participation is evaluated based on the contribution of the student to the sessions. A student is evaluated on participation only if the student attends at least the 80% of the scheduled meetings and classes.

Previous capacities

It is mandatory that the students have previous knowledge about software architecture and software design

It is desirable that the student knows the Unified Modelling Language (UML) as we will use it as standard notation to describe the proposed design solutions
