13. June 28 th – July 1 st 2006 Local Persistence Service  Allows offline data access  Provides common API for creating, reading, updating, and deleting local data  Adapters are used for different types of local data storage devices  Local Shared Objects adapter is available in Flex 2.0… FDS is not required  Offline data synchronization supported through combination of local persistence and messaging services… FDS is required!

14. June 28 th – July 1 st 2006 Show me how…  Using C-FDS for: High-performance, SECURE access to CFCs with native data results Coldfusion application  Flex application messaging Note: Mike Nimer’s presentation will show CFC Actionscript native translations during data marshalling  Using FDS for: Proxy security & framework for access to distributed data systems. Coldfusion application  Flex application 2-way messaging Paging large volumes of data Real-time Data Sharing Messaging for Dashboard features Introduce Flex 2 Actionscript components for FDS and show source examples: See notes!

15. June 28 th – July 1 st 2006 Using CFCs with C-FDS <mx:RemoteObject id="myCfc" destination="ColdFusion" source="myApplication.components.User“ result="my_CFC_handler(event)" /> a) Modify /WEB-INF/flex/services-config.xml to add a “named” destination 1)Specify in.mxml file a CFC component with its FULL class path… this may be a security concern! 2)Modify FDS configuration file to specify an private, custom ID for the desired classpath. Use this ID in the Flex code… SECURE and PRIVATE. b) <mx:RemoteObject id=" myCfc " destination="CustomID" result="my_CFC_handler(event)“ /> See code samples…

16. June 28 th – July 1 st 2006 FDS for Data Sharing 1)User is ordering online and is submitting an invalid credit card for his order. 2)Instead of get some abstract error… an online representative “pops-up” asking if the buyer needs help. 3)The buyer says yes and describes the problem. 4)The rep fixes the fields REMOTELY and submits the buyers form REMOTELY. 5)The buyer receives confirmation 6)The rep thanks the buyer and logs-off. See code and demo… Real-time, 2-way data sharing (e.g. medical insurance forms, decision support systems, etc)… Let’s review a Flex application to allow online support to help with credit card problems on a visitors form. Scenario:

17. June 28 th – July 1 st 2006 FDS for Dashboards 1)UserA is ordering online orders several products. UserA submits order. 2)UserB is ordering online with several products. UserB submits order. 3)Etc. 4)Each time an order is submitted the dashboard AUTOMATICALLY adjusts its charts/graphs of gross sales and available inventory. See code and demo… Real-time, data aggregation (e.g. medical, decision support systems, etc)… Let’s review an application to allow multiple online buyers to submit orders that update sales and inventory dashboard. Scenario:

18. June 28 th – July 1 st 2006 Use FDS 2 with ColdFusion  Server-side Security  Performance & Functional Testing  Collaboration  Large volumes of data with paging  Data-Push Features  Client Synchronization  Real-time data delivery (e.g. medical, investment, decision support systems, etc) Flex Data Services RPC ServicesData Services Message Service
