Overview

This course provides a brief introduction to the concepts of Service Oriented Architecture before going into the details of Service Oriented Analysis and Design. This course will help the participants understand how requirements are captured, business processes are modeled and services are identified. It describes the principles of service orientation. The principles will act like a checklist against which you can validate your own design.

Audience

Business Analysts, developers, architects and any other technical IT staff involved in designing SOA applications.

Skills Gained

  • SOA Fundamentals
  • Introduction to Service Oriented Analysis and Design (SOAD)
  • Software Methodology
  • Requirements management for SOA

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.

Submit an enquiry from any page on this site and let us know you are interested in the requirements box, or simply mention it when we contact you.
