Distributed applications: APIs and web services (EN/NL/FR)

During this training, we will learn how distributed applications can be created. This one-day course at ABIS will give an overview of the possibilities, starting from the classical web services, to the nowadays more used REST APIs.

Service Oriented Architecture (SOA) is nowadays the main architectural style for business applications. It promotes loose coupling and interoperability, so that end-to-end business applications can easily be built from a set of business-aligned services. (SOAP) Web services and REST APIs are the most common implementations of these SOA ideas.

In this course:

• participants get an overview of SOA principles: the concepts, the standards, the products and implementations
• participants will learn how applications communicate using HTTP and XML/JSON
• the evolution from the (classic) SOAP web services to REST APIs and microservices will be discussed
• documentation and maintenance of APIs will be discussed

Intended for

Analysts, application developers, database administrators or project leaders wanting to learn the basic ideas of creating web services and APIs.
