RE: [flexcoders] Flex for database apps; compare to .net
I'm pretty new to .net also, so I suppose flex data services would be about the same learning curve. FDS, would it have any advantages over taking a .net approach? I seem to recall that FDS/LCDS has two way update notification/synching services or something of that order, which I took to mean that the flex ui would be updated passively if changes are made to the viewed data by another user? Would that be hard to emulate in .net, or would fluorine or WebOrb be able to help with that? Fluorine would connect flex and the .net side. But I'm not clear what the .net methods that you describe are exactly? Would they be a set of classes that call sprocs in the sql server db, either built manually or as generated by an ORM? I'm not clear on the limitations of the free version of LCDS, and what it costs if you need to go beyond the limitations of the free version? Samuel R.

An exact date has not been announced for Flex 3 release, but they've said Q1 2008.

Re: [flexcoders] Flex for database apps; compare to .net
Thanks, I'll focus on 3.0, though being new to flex and with the docs for 3.0 somewhat thin now, not sure what I'll be able to figure out. I hope adobe provides some straightforward db oriented tutorials, web services play only a minor role in most of my fellow developer's workload, db interaction is where it's at. I'd appreciate anyone else's input on these subjects.

Re: [flexcoders] Flex for database apps; compare to .net
Michael, You want to compare Eclipse vs VS, or Flex vs Silverlight In particular, if you are considering data centric application you will most likely need anothe Eclipse plugin that automates data access for Flex I am using (and adding functionality ) to Clear Data Builder (myflex.org). It can be used as simple CRUD generator that also gives you flexibility to add any customization Regards Anatole Tartakovsky Farata Systems On 11/10/07, Michael Pengi [EMAIL PROTECTED] wrote: I am considering flex for building data centric applications for use over the lan or internet.
