Description

Inescapable standards in the exchange of textual data on the Web, XML and JSON have taken a major place in Web applications, information systems, data and application integration. For its part, XML, the basis of many other languages, is surrounded by a multitude of tools for the definition and manipulation of data. JSON, for its part, offers a simpler data format and integrates more easily with programming languages. This seminar offers you an exhaustive vision of the uses of XML and JSON within information systems.
