History of Web-Technologies Analysis of Web-Architectures The Thin-Server-Architecture Advantages of TSA-webapps Example and Trends Discussion and Questions

Before the web was born

Before

desktop-applications with techniques and known patterns

like MVC since 1979

12 years later

The web was born

→ Need to invent totally new conceptsor

JSONQuery/JSONPath JSON Referencing Comet Live Data Notifications JSON Schema with evolutionary constraints JSON-RPC Built-in Security Standards based REST interface

DHBW-Mannheim, David Amend

REST

It´s an architectural style Not a format or API

The web has leveraged REST Can/should be used for web services One interface for all applications Manipulation of ressources over URL:

GET, POST, PUT, DELETE
