The goal of this course is for students to:

1. deepen their understanding of Service-Oriented Architecture
2. get familiar with designing services and business processes,
3. learn about web services and the related standards,
4. learn about the BPEL and BPMN standards for describing business processes
5. learn about the capabilities of an ESB
6. be able to create web services on different platforms (.NET and Java)

1. Service-Oriented Architecture (SOA)

History of SOA in the light of earlier technologies (distributed object-orientation, distributed components). The definition of SOA, the principles of SOA.

2. Web services

XML namespaces, Web Services Description Language (WSDL), communication protocol of web services (SOAP).

3. Developing web services

Web service APIs: .NET Windows Communication Foundation (WCF), Java API for XML-based Web Services (JAX-WS)

Practice: creating a simple web service in .NET and in Java, examining the WSDL interface, logging and examining SOAP messages

4. Developing complex web services

Enabling middleware (WS-*) protocols for web services: configuration (WS-Policy), addessing (WS-Addressing), reliable messaging (WS-ReliableMessaging), secure messaging (WS-Security, WS-SecureConversation)

Practice: creating a complex web service in .NET and in Java, examining WS-Policy configurations, logging and examining complex SOAP messages

5. Lightweight web services

The REpresentational State Transfer (REST) technology and its principles, comparison of REST and web services

6. Developing lightweight web services

REST API-k: .NET-ben a Windows Communication Foundation (WCF), Java-ban a Java API for RESTful Web Services (JAX-RS), JavaScript Object Notation (JSON)

Practice: creating simple REST services in .NET and in Java, logging and examining messages

7. Design and development guidelines for web services

Advantages and disadvantages of bottom-up (code first) development, advantages and disadvantages of top-down (WSDL first) development, hybrid development, interface design principles, versioning interfaces, architectural consideration of Java and .NET applications

8. Testing web services

Principles of testing web services, unit testing, integration testing, regression testing, running external test, test frameworks

Practice: testing complex web services with different methods

9. Describing executable business processes

Elements of the Business Process Execution Language (BPEL) language, connection of BPEL with web services

Practice: designing a simple BPEL process, calling external web services from the process

10. High level description of business processes

The Business Process Modeling Notation (BPMN) language, comparison of BPMN and BPEL, mapping BPMN processes to BPEL

Practice: designing a simple BPMN process and making it executable

11. Integration tasks

The Enterprise Service Bus (ESB) for integrating various technologies (database, FTP, SMTP, web services, etc.), routing and transforming messages, processing events, management

Practice: integration using an ESB, including message transformation and event handling

12. Business rules and human tasks

Outsourcing frequently changing business rules from the process, accessing human activities from processes

13. SOA tools and frameworks

Comparison of the most important SOA tools and frameworks in the industry

14. Homework submission

Checking the homeworks of the students

a. In lecture term:

During the semester a homework has to be completed. The condition for acquiring a signature is the acceptance of the homework.

b. In exam term:

Written exam for those who acquired a signature.

Recap of the homework is possible on the replacement week, subject to paying a fee.

Based on the demand, appointed with the lecturer.
