It is late evening. Something is wrong with a database. You narrow down the possibilities, getting more frustrated and puzzled. Stay calm. Check the inputs systematically. No! The data going into that table is right, but when you then read it in the table, it's wrong. Why did I stop believing in the supernatural? Then it hits you. Every time it comes as a surprise.

SQL Server Integration Services (SSIS) can be used effectively as a tool for moving data to and from Windows Azure SQL Database, as part of the total extract, transform, and load (ETL) solution and as part of the data movement solution. SSIS can be used effectively to move data between sources and destinations in the cloud, and in a hybrid scenario between the cloud and on-premise. This paper outlines best practices for using SSIS for cloud sources and destinations and for project planning for SSIS projects to be used with Azure or hybrid data moves, and gives an example of maximizing performance on a hybrid move by scaling out the data movement.

Corrupt SQL Server databases are the worst nightmare of any SQL Server professional. In any environment, from small business to enterprise, the compromise of integrity and availability of the data can constitute a business emergency.

SQL Server database corruption and disruption of the transaction processing system can cause business repercussions such as large financial losses, a drop in reputation or customer retention, or contractual SLA problems with the service provider, if not managed in-house.
