That's a great idea; I've worked on a couple of apps that distributed read-only copies of the data (and the web app that presents it to the user) worldwide so that the data was available locally (relatively-speaking, within the same continent, island or region) to the viewers, but one writeable database got all the inserts and updates, and master-slave replication shipped all those changes out to the read-only slaves. Obviously, this only works in situations where slightly lagging response to updates on the slaves is acceptable. That combines the high availability and rapid response of a local server with the integrity and reliability of single point for database changes. For the right kind of app, it can work well. -- Ted Roche Ted Roche & Associates, LLC http://www.tedroche.com _______________________________________________ Post Messages to: [email protected] Subscription Maintenance: http://leafe.com/mailman/listinfo/profox OT-free version of this list: http://leafe.com/mailman/listinfo/profoxtech Searchable Archive: http://leafe.com/archives/search/profox This message: http://leafe.com/archives/byMID/profox/[email protected] ** All postings, unless explicitly stated otherwise, are the opinions of the author, and do not constitute legal or medical advice.
