http://www.macromedia.com/software/dataconnection/demo/

Note the following in the demo

You can filter records by inputting data.

You can sort by clicking on column header. You can resize the columns

You can see realtime data changes. Notice how updates are immediately reflected and formulas calculated.

Shadowing
If you change data and add notes,they are stored as a Delta Packet and sent to the server ( when connection is there). So you can even work offline.

Connecting To Different Data Sources
You can switch among different data sources. Changing data sources requires no code changes in the application.
