| | Database - Wikipedia, the free encyclopedia |
 | | The computer program used to manage and query a database is known as a database management system (DBMS). | | | Databases are used in many applications, spanning virtually the entire range of computer software. | | | One possible definition is that a database is a collection of records stored in a computer in a systematic way, such that a computer program can consult it to answer questions. |

| | Database transaction - Wikipedia, the free encyclopedia |
| | If one of queries fails the database system may rollback either the entire transaction or just the failed query. | | | When this happens it is usually important to be sure that the database is not left with only some of the queries carried out. | | | A single transaction might require several queries, each reading and/or writing information in the database. |

| | Transaction Logging Concepts |
| | Because database changes are buffered in memory and are written back to disk only when it becomes necessary to do so, as more and more database changes are made, the disk-resident copy of the database becomes more and more out of date. | | | If the database manager were to write changed database blocks back to disk only when the database was shut down, then when a failure occurred, the crash recovery operation would have to repeat every change made since the start of the session. | | | Transactions are an error handling mechanism and a program structuring mechanism. |

| | The Cornerstone Of Crash Recovery |
| | In a future column, I'll show you how to use transaction log files to replay operations to return the database to the exact state it was in at a given point in time. | | | (An inconsistent database will generate a return code and error message each time an attempt to establish a connection is made.) You can't recover transaction records that were stored in memory, but you can return an inconsistent database to a consistent, usable state by performing an operation known as crash recovery. | | | Then I'll show you how to use the information stored in a database's transaction log files to return a database to a consistent and usable state after a system crash or program failure. |

| | Issues with Transaction Log Files When Moving an Exchange Mailbox Database |
| | Therefore, to move a database to a new storage group and log stream, you must first ensure that the database files are in clean shutdown state. | | | For example, if databases are in C:\Databases at the time a series of transaction logs is generated, and you later move the databases to D:\Databases, then subsequent transaction log replay will result in a “File not found” error. | | | This change is what happens when you move a database from one storage group to another one. |
