Can a SQL trigger call a web service?

Question

I\'m building out a RESTful API for an iPhone app.

When a user \"checks-in\" [Inserts new row into a table] I want to then take data from that insert and call a web

Answer 1

A good practice is to have that web page make an entry into another table (i will call message_queue ) when the user hits the page.

Then have a windows service / *nix daemon on a server scan the message_queue table and perform the pushes via a web service to the mobile app. You can leverage the power of transaction processing in SQL to manage the queue processing.

The nice thing about this approach is you can start with everything on 1 stand alone server, and even separate the website, database, service/daemon onto different physical servers or server clusters as you scale up.
