We are going to explore if corporations should be utilizing Amazon AWS Oracle Database related services (EC2, RDS ), how it should be used, where possible savings and potential trouble points are.

We expect NoSQL databases to come up with such query languages in near future. In meantime, Quest's Toad for Cloud fills this gap and makes it easy to seamlessly access NoSQL, Cloud and ... (more)
