Recovery Toolbox for SQL Server is an all-in-one MS SQL database repair solution for corrupted MDF/NDF files. Recovery Toolbox for SQL Server helps to repair mdf files and recover data from suspended databases

SQL Database Repair

The process of repairing a SQL Server database is a complex task consisting of several steps. The procedure of fixing SQL Server corruption involves restoring the MDF file in which all database objects are stored:

Tables
Stored Procedures
Functions
Triggers
Indexes
Viewers

Recovery Toolbox for SQL Server works on the basis of a very complex algorithm of SQL database repair from Microsoft. In order to repair database SQL Server, the first step is to define and identify the pages of the data blocks inside the file. A page is just a universal block of data storage in an MDF/NDF file. The block size tin can exist set up by the database administrator. By default, the folio size is about 8K bytes. Each page of the repaired MDF file has a unique index and number. Based on this unique information, you tin filter out irrelevant and unused page numbers when trying to repair SQL database. Extra pages commonly appear when modifying or deleting user data in an MDF file. Recovery Toolbox for SQL Server excludes redundant pages when going to repair SQL databases, so that the data is not duplicated and just actual information is transferred to the recovered data. Subsequently completing SQL Repair Database, deleted or modified records or tables should be excluded from the recovered MS SQL databases then that their integrity is not compromised.

How to repair MDF file

MDF repair cannot exist done merely past fixing or modifying the contents of a damaged MDF file. An MDF file has a complex structure with multiple connections between objects. Appropriately, the slightest edits inside the corrupted MDF file will atomic number 82 to a violation of the integrity of the data and further complicate the recovery of the MDF file. This, in turn, may lead to increment of fourth dimension required to repair database MSSQL, or overall loss of the possibility to repair SQL DB. Therefore, to reply how to repair MDF file, it is necessary to completely understand the process.

The process of MDF file repair is carried out in several stages:

Clarify of the construction of an MDF file
Select pages that store data
Structure data pages in an MDF file
Delete of redundant pages to avoid duplicate content
Highlight organization data that describes the construction of the stored information
Assemble disparate information into shared structures of tables, indexes, and other objects
Save data as separate files every bit SQL script (*.sql files)
Create a New Database in MSSQL Server
Sequential import data from SQL scripts (*.sql files) to a new database
Replace a corrupted database with a new MDF file (new database)

As a result of repair SQL Server database, afterward importing all the data extracted from the corrupted MDF file into a new database, this new database is considered to be a repaired SQL DB; and the MDF file of the new database, created during repair MS SQL, is the recovered MDF file. In other words, this algorithm allows Recovery Toolbox for SQL Server repair database MS SQL by creating a working version of information technology, which is the exact copy of the original file before information technology got damaged. To repair an MDF file, you starting time need to restore the data (tables), and so all other user objects (Stored Procedures, Functions, Triggers, Indexes and Viewers) are restored. In other words, the recovery of an MDF file goes through an intermediate step: saving the information to .sql files. As a outcome, the corrupted MDF files of the damaged MSSQL Server database are non edited or modified in the process of repairing SQL databases.
