Albus Dumbledore- Dumbledore means bumblebee, which I suppose. would fit... Draco Malfoy- Draco meaning dragon or refering to a cruel Athenian lawmaker. The mal in Malfoy meaning evil or bad, and foy, more commonly know as foi in french, means faith, so Malfoy would mean Badfaith.
Transactions (Transact-SQL) A transaction is a single unit of work. If a transaction is successful, all of the data modifications made during the transaction are committed and become a permanent part of the database. If a transaction encounters errors and must be canceled or rolled back, then all of the data modifications are erased.
The Transaction Log provides the means by which either the complete set of tasks of a database transaction are performed or none of them are. It ensures that , via rollback, only valid data is written out to the database, and it allows transactions to be played back to recreate the system state right before a failure.
