pulling data from Web sesrvice

Hi All,

Need your suggestion and guidance.

I need to pull data from 4-5 tables of Navision 4. database tables to my local SQL database. Now I’ve written a webservise which will pull out the data for every 15 mins.

Now I do not want to pull the data for every 15 mins, rather, if there is ANY changes in these tables, I want to pull. Please, experts please let me know what is the best way to do it.

Thanks in advance.
