Every database created and managed by Microsoft's SQL Server 2005 and SQL Server 2000 contains at least one transaction log file and data file, and these can cause some types of database corruption problems, according to Gram Smith's SQL recovery database blog.

Smith, an expert IT professional, writes that "logging the transaction details can't be turned off because transaction integrity is conceived an intrinsic and fundamental characteristic of MS SQL Server. In case of corruption or loss of transaction log file, you may come across SQL Server Database corruption. In such cases, you are required to perform SQL Database Recovery to retrieve data."

SQL database recovery, Smith says, uses a number of technically advanced processes to help IT professionals recover information stored in corrupted databases. The graphical user interface helps make these processes more accessible to the tech workers trying to save the data, however.

The SQL recovery tool also works well in the recently released SQL Server 2008 R2 version, though that framework is less susceptible to corruption errors of this type, experts say.
