DT offers a core set of courses aimed at covering the Application Lifecycle, from requirements gathering, analysis and design to development, testing, process and project management.

SOA Services Oriented Software Design

Course Overview
This course provides a solid overview of applying Component Based Development/Design using UML. The context is a Service Oriented Architecture (SOA) in which a Service Oriented Process (SOP) is applied.

What will I learn?
This course is targeted at Architects, IT managers, Analysts, Designers.

General knowledge and understanding of software development (processes) is assumed. No prior knowledge of UML is assumed, but is a benefit.
Detailed description

It is important to understand that this is not a Web Services course. This is more a Course on Service Orientation (SO) explaining the techniques involving:

* The SO Architecture
* The SO Software Development Process
* SO Technologies

The role of Web Services is explained in the SO Technologies section. This course will clearly explain that Web Services is merely one of the many technologies used to implement an SOA.

This course guides the student through the steps of using UML and BPMN to define a system that is comprised of service and components. The overall architecture of such a system is the Service Oriented Architecture. The student will learn how the use different UML and BPMN models and understand their semantics in an SOA. Furthermore students will learn techniques used in most Software Development Processes that deliver a system in terms of components and services, a so called Service Oriented Process (sometimes also referred to as a CBD process).

The course will illustrate the significance of Business Process Models and how they help the further development of the IT Model. Students will learn how BPM can aid in defining services, components, service operations and orchestrations.
