ttsiod recommends a blog entry in which he details steps to apply Reed-Solomon codes to harden data against errors in storage media. Quoting: "The way storage quality has been nose-diving in the last years, you'll inevitably end up losing data because of bad sectors. Backing up, using RAID and version control repositories are some of the methods used to cope; here's another that can help prevent data loss in the face of bad sectors: Hardening your files with Reed-Solomon codes. It is a software-only method, and it has saved me from a lot of grief..."

For example: x=30, GROUP BY (year), SUM (sales), HAVING MIN (age) > 18. The primary reason for the tool was to avoid Cartesian joins and loops in SQL written by hand, with many joined tables. The database will execute such a statement, if syntactically correct, resulting in runaway queries that can bring the database down. If you sit close to the DBAs, you can hear them screaming... "
