ACID (an acronymn for Atomicity Consistency Isolation Durability) is a concept that Database Professionals generally look for when evaluating databases and application architectures. For a reliable database all this four attributes should be achieved. Atomicity is an all-or-none proposition. Consistency guarantees that a transaction never leaves your database in a half-finished state. Isolation keeps transactions separated from each other until they’re finished. Durability guarantees that the database will keep track of pending changes in such a way that the server can recover from an abnormal termination. Above four rules are very important for any developers dealing with databases. Ref: http://blog.sqlauthority.com/2007/12/09/sql-server-acid-atomicity-consistency-isolation-durability/ - ACID (atomicity, consistency, isolation, and durability) is an acronym and mnemonic device for learning and remembering the four primary attributes ensured to any transaction by a transaction manager (which is also called a transaction monitor). These attributes are: Atomicity. In a transaction involving two or more discrete pieces of information, either all of the pieces are committed or none are. Consistency. A transaction either creates a new and valid state of data, or, if any failure occurs, returns all data to its state before the transaction was started. Isolation. A transaction in process and not yet committed must remain isolated from any other transaction. Durability. Committed data is saved by the system such that, even in the event of a failure and system restart, the data is available in its correct state. The ACID concept is described in ISO/IEC 10026-1:1992 Section 4. Each of these attributes can be measured against a benchmark. In general, however, a transaction manager or monitor is designed to realize the ACID concept. In adistributed system, one way to achieve ACID is to use a two-phase commit(2PC), which ensures that all involved sites must commit to transaction completion or none do, and the transaction is rolled back (see rollback).

Use program way backup and recovery. Tool repair sql database any version starting with MS SQL Server 2000, including SQL 2005.-------------You can backup SQL server database using SQL Server Management Studio (SSMS), T-SQL or PowerShell.Limitation: Backup created using higher version can't be restored in earlier version of SQL server.

A SQL recovery tool (see below) will help you repair corrupted .mdf files, tables, views, stored procedures, rules, defaults, user defined data types and triggers from Microsoft SQL server database & effectively recover large SQL Server database. Recover sql server databases thanks to programmed method I would recommend you next utility
you can not open the sql server back up file in access. You have to use server wizard to see the data base provided. It it not simple access or excel file. AnandDave.
MDF stands for Master Database File. It is a primary database file in SQL server, you can't start SQL server without mdf file.
There is no such thing as SQL Server 2003. Microft released SQL Server 2005 as the next version of SQL Server 2000.
SQL stands for Structured Query Language as it refers to the type of database query or database server which accepts the query.
MySQL, while not an acronym, is a free SQL database server. The SQL stands for Structured Query Language. This database server runs on Windows, Linux, and Solaris machines.
PL\SQL is an Oracle product (the PL stands for procedural language), while Sql Server most commonly refers to Microsoft SQL Server, although at one point Sybase also marketed its product as Sql Server. Microsoft and Sybase both have a procedural language feature, called T-SQL (Transact-SQL), which is similar in concept to PL\SQL, but there are significant differences in syntax and structure. An experienced developer could convert PL\SQL to T-SQL readily, but conversion would be required. It would not run without conversion.
