Database corruption recovery systems and methods

The subject invention pertains to data store corruption recovery. More specifically, the invention concerns systems and methods for identifying corrupt data in a manner that prevents de-committing or removal of valid or consistent transactions from a database. This can be accomplished at least in part by logging the identities of data items that a transaction reads. Furthermore, the subject invention provides for employment of a multi-version (or transaction-time) database to reduce significantly reduce any down time or database unavailability caused by a corrupt transaction and associated corrupt data items. Accordingly, no backups need to be installed and only updates by the original corrupt transaction and transactions that read corrupt data need to be de-committed or removed.
