Cloud Storage Replication Is Not Backup
The options that you need to select when setting up an Azure Storage service account allow you to specify the durability and high-availability of your data, but they don't provide for data recovery to a point-in-time.

An article about how we underestimate the power of joins and degrade our query performance by not using proper joins
Another Look at Tuning Big Data Queries
Most large organizations have implemented one or more big data applications. As more data accumulates internal users and analysts execute more reports and forecasts, which leads to additional queries and analysis, and more reporting. The cycle continues: data growth leads to better analysis, which generates more reporting. Eventually the big data application swells with so much data and querying that performance suffers.

The DRI Subject of References
A database must be able to maintain and enforce the business rules and relationships in data in order to maintain the data model. It does this through referential constraints. They aren't complex, but are powerful, especially with the means to attach DRI actions to them. Joe Celko explains all, and pines for the ANSI CREATE ASSERTION statement.
