Hi,

you can certainly use Lightstreamer to reach your goals, but you can't use Lightstreamer as is. You have to implement your adapter that fetches the data from your DB/front-end and injects them into the Lightstreamer kernel.

You should start reading the GETTING_STARTED.TXT and DOCS-SDKs/General Concepts.pdf files available in Lightstreamer distribution for a better understanding of the software.
