3 Legacy migration the Future! Existing software - Refine and fix. New software - Recreate, redefine and reintegrate.

5 So what s wrong with the old model? Lack of support for different hardware Programs were compiled to x86 code. Weak integration with Internet/WWW Code and WWW code where seen as separate entities Code.asp Code.asp <% <% %> %> val1 = 10 val1 = 10 val2 = 20 val2 = 20 result = Cstr(val1) + Cstr(val2) result = Cstr(val1) + Cstr(val2) response.write "<BR>Value is " & result response.write "<BR>Value is " & result result = val1 + val2 result = val1 + val2 response.write "<BR>Value is " & result response.write "<BR>Value is " & result Difficult to integrate different languages Poor version control for system components Lack of security Integration Most programs where written with little care about security Version 1.1 Version 1.2 Version 2.0

6 So what s wrong with the old model? Poor robustness Where applications often crash Too much support for legacy code Poor integration with different data sources, such as XML, databases, and text files. Difficult deployments Lack of sharing between applications Poor pre-run checking This is where applications often crashed on run-time

21 What s required? Complete integration of graphics, text, documents, 3D, animation, and so on. Scripted or coded.

Rich Internet Applications HTML/CSS. Good for layout, poor for animation/graphics. AJAX (re DHTML 1998). Simple to upgrade legacy to a more richer experience. Poor incompatibility. Adobe Flex.

Supports ActionScript with Flash. JIT code. Flash 9 Player. MXML to create GUI, ActionScript 3.0 for coding. Flex Framework buttons, controls, etc. WPF..NET 3.0 Integrates Windows Applications and Web. WPF/E can be used everywhere. Java applets. Integrate into Web applications.

Windows Presentation Foundation - Supports Forms/ Media/ 3D Graphics/ Animations/ Documents - Replaces Windows Forms - XAML (exensible Application Markup Language) XAML or C#

23 Windows Presentation Foundation - Supports Forms/ Media/ 3D Graphics/ Animations/ Documents - Replaces Windows Forms - XAML (exensible Application Markup Language) XAML or C# code Documents Graphics Forms 3D Animation Media Windows Presentation Framework - Framework for User Interfaces [prev. Avalon] Business Logic (decoupled from the user interface)

24 XAML (XML Application Modeling Language) Both these technologies have vastly simplified the programming model for doing animations on your User Interface. Either Markup (XML) or Code (C#/AS3) XAML file - Storyboard - Ellipse from opaque to transparent in one second <Grid> <Canvas margin= 30 width= 230 height= 230 Background= Gray > <Canvas.Resources> <Storyboard x:key= fade > Define the element to be animated <DoubleAnimation Storyboard.TargetProperty= (Ellipse.Opacity) Storyboard.TargetName= e1 From= 1 To= 0 Duration= 0:0:1 /> </Storyboard> </Canvas.Resources> <Ellipse Name= e1 Canvas.Left= 100 Canvas.Top= 0 /> </Canvas> </Grid> Example
