SOA: contribution, solutions and implementation

Led by
Description
Length

Agility and responsiveness: these are the new requirements companies are expressing in relation to their information systems. Business 2.0 is “agile” and seeks to align its information system with its strategy and business areas.
That being the case, businesses need to be able to organise their information systems so that they support business processes which are, by nature, cross-functional.
Application mapping, systems planning and a process approach are necessary ahead of this process.
Technically, SOA responds to these challenges by providing a methodology and tried and tested concepts.
You will learn about SOA best practices and technologies for implementing them. Practical work ensures that a concrete approach is maintained.
