WA1789 Designing and Developing RESTful Services Training and Courseware
(Coming Soon)
|
When all you have is a hammer…everything looks like a nail. Although many of the services in active use are SOAP or at least XML-based, an increasing number of services take a RESTful approach to data transmission. Representational state transfer (REST) is a style of software architecture that differs from the more traditional Remote Procedure Call (RPC) style of data transmission, instead emphasizing the importance of defining and retrieving representations of resources.
This course explores the principles, practices, and application of REST as a software architecture methodology. While much of the learning could be applied to any REST compatible implementation, emphasis will be placed upon the design and development of RESTful Web Services.
This hands-on course is aimed at architects and developers that want to learn how to design and develop RESTful services that fully comply with the full range of the RESTful design methodology. Students will learn to define and work with such REST elements as resources, components, and connectors. Furthermore, emphasis will be placed upon the definition of a REST interface and the management of multiple representations for a given resource. All concepts are reinforced through detailed, hands-on labs in a vendor-neutral context. |
