Continuously querying a datastream using SQL Server 2005

I was wondering if it is possible to continuously query a real-time
datastream using SQL Server. Does anyone have any experience of this? I
have found LINUX based systems such as Borealis and STREAM. I would
prefer to use a Windows based system as the program using the query
results is Windows based.

What more exactly what you want to achieve? Query notification is the first
thing that comes to mind, but it may not be exactly what you are looking
for.

Erland,

Query Notifications look like they would do the job alright but it
would mean writing each new piece of data to a table, querying it, and
then pulling the result back into my program. If this is the only
solution then I would probably be better dealing with the data-stream
within the program as speed is a huge factor and recording the data is
a secondary concern. My main question was whether there is specific
functionality within SQL Server to deal with real time analysis of data
streams?

Thanks,

Paul.

Well, the main purpose of a database engine is to record the data. To me
it sounds like you are looking for a solution without an RDBMS.

Well, I thought SQL Server may have some real time data analysis
capability. Obviously it is not equiped for this. I guess I'll have to
stick to the LINUX based packages I am currently using. Probably faster
anyway.

Thanks,

Paul.
