Agenda

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

is it reinventing the wheel?

TSA = SOA-Front-End-Architecture = Loose coupling


Vision:Web-Oriented-Infrastructure


A possible future? Google: GoogleWebToolkit, Gmail,

GoogleDocs, JavaScript-APIs, … Apple: Appstore switched to Sproudcore-MVC Clientcentric Standards: HTML-5

(Multimedia, Offline-Database, Synchronizing, WebSockets,...), CSS-3, ECMA-Script-5





The future of web-applications?





The future of web-applications?→ What do you think?


Discussion

Server Code Client

Thank you for your attention!

Questions?


MVC-architecture pattern via JavaScript Ajax and DOM functionality via jQuery No server needed for development Java-JavaScript-Interpreter: Rhino Testing: browser based, command line,

browser driver


Web-Infrastructure Challenge


Summary

Advantages of Rich-Internet-Applications Limits of web framework architecture Possibility and advantages of building

clientcentric apps Companies already invest in RIA-technologies The future?

Server Code Client


Intelligent clients = more possiblities


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


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
