I'm recording some videos where I provide technical background about data replication. I've created a YouTube channel to collect them all together. The channel is "James Talks about Data Replication". Here's a link:
I've uploaded two so far. The first one discusses the special considerations you should be aware of when using data replication with tables that have duplicate rows. The second discusses the role of data replication when moving to a real time operational analytics system from a traditional batch oriented data warehouse.
