The document discusses the RISC Browser Architecture as a paradigm shift for building user interfaces with HTML. It proposes moving away from traditional frameworks with many elements and attributes towards a microkernel approach based on only rectangles and text input. This reduces complexity and regains control over layout, performance and compatibility. The RISC approach also separates concerns better by decoupling frontend rendering from external libraries or frameworks.

35. CaptainCasaEnterpriseClientRISC
Which are the basic elements that „any“
user interface can be built with?

36. CaptainCasaEnterpriseClientRISC
What are the basic elements which
of even complex user interfaces?
1. Rectangles
- with/without text
- with/without background styling
2. Textinput
- single line
- multi line
(3. Graphics)
...and the possibility to
A. position them absolutely (x,y,width,height(,z))
B. compose them

Ist „Server-UI“ old school?
• Server-centric UI
– Server state!
– Große Nähe zur Logik
– Effiziente Entwicklung auch komplexer Szenarien
– Function / Data driven
– ==> Sachbearbeiter
• Client-centric UI
– Server stateless
– Kernlogik nur remote erreichbar
– Aufwendige Entwicklung
– Design driven
– ==> Endkonsumenten
