[flexcoders] Re: Need Suggestions for database application.
PHP is good for server-side and there are frameworks that will help you encapsulate database layer so you can easily switch from one db engine to another e.g. MySQL to PGSQL,etc. Built in PHP is PHP Data objects library that can help you with this problem as well if you need a thin layer for your database layer.

Oh... That's interesting. I could use attributes instead of nodes.
Thanks.

[flexcoders] Re: Help on DataGrid dataProvider
Thanks a lot. I followed your recommendation and it worked.
I though that flex automatically fetched the field names from the xml as in the
case of default resultFormat i.e. object.
I guess for e4x, the dataGridColums must be explicitly specified.
Thanks again.

Hello guys, A newbie here. I have this code: http://www.adobe.com/2006/mxml"; layout="absolute" creationComplete="bookData.send()"> How do I get the datagrid to be populated with rows? The alert.show calls somehow get the data. What am i missing here? JC
