The course overviews the conceptual and applicative elements related to the area of Service Oriented Architectures (SOAs) and AI Interfaces. The main objective of the course is to provide students with the knowledge on how to build service oriented architectures starting from the development from scratch of new services, by integrating third-party services, or by using AI-based APIs. Moreover, the course aims at investigate the aspects related to the process of integrating and engineering SOAs. At the end of the course, the student acquires the knowledge on: • the main aspects and concepts linked to SOAs; • the elements to build and develop software systems based on SOAs and to define quality characteristics of the services and architectures; • the applicability of these concepts to real SOAs and Services, and AI Interfaces; • the hot research topics and emerging technologies in the field of SOAs and Web Services. Acquiring knowledge and understanding At the end of the course, the student acquires the knowledge and understanding to analyse a SOA and Web Services from a functional and also non-functional point-of-view. Applying knowledge and understanding At the end of the course, the student is able to apply techniques, methodologies, and tools to engineering and develop SOAs and Web Services, also by using and connecting AI-based APIs. Judgement At the end of the course, the student is able to judge in an autonomous way the existing SOAs both from a functional and also non-functional point-of-view. The student is able to understand the characteristics of equivalent Web Services and he/she is able to select third-party services and SOAs following specific functional and non-functional requirements. Communication Skills At the end of the course, the student is able to use and adopt the correct terminology related to SOAs and Web Services. Moreover, the student is able to describe the whole process to engineer and develop a SOA or a Web Service by using the related technical language and English keywords.
