1. SQL Server used to store the collection of related data and data is a collection of facts and figures that can be processed to produce information

2. A SQL management system stores data in such a way that it becomes easier to retrieve, manipulate and produce information.
3. In-database data stored in form of numeric, text images and other formats.
4. SQL Server provides a command prompt screen using a command SQL CMD.A user work in this command prompt screen to create databases, even run SQL scripts.

A Structured Query Language (SQL)SQL is an ANSI standard language for accessing and manipulating databases. This Language used to Communicate, managed the database in the SQL Server. SQL work with Relational Database Management System. This Language help in adding, deleting and updating the data store in Row and Column form in the database.

A SQL Commands use to manipulate data in SQL Server. These can be used to create updated and maintained the database in

SQL Server. These Command are divided into 5 categories.

1) Data Definition Language(DDL): A DDL Statements used to define the structure or Schema of the database. A Schema is a logical structure created before the values stored in the database. Example.

CREATE -: create a database and its objects such as index, views, triggers and functions.

ALTER -: alters the structure of the existing database

DROP -: delete objects from the database

TRUNCATE-: remove all records from a table, including all spaces allocated for the records are removed

COMMENT-: add comments to the data dictionary

RENAME-: rename an object

2) Data Manipulation Language(DML): Commands are used for managing data within schema objects of database Some examples:

INSERT -: insert data into a table

UPDATE -: updates existing data within a table

DELETE -: deletes all records from a table, the space for the records remain in the database.

3) Data Query Language(DQL): Command in SQL server use to retrieve the data from the database.

SELECT -: retrieve data from the database.

4) Data Control Language(DCL): Commands used to control the rights and permission in the database system.

GRANT -: allow users to access privileges or right to database.

REVOKE -:withdraw users access privileges given by using the GRANT command

5) Transaction Control Language(TCL): TCL Commands are used to control the transaction made against the database system.

COMMIT -: commits the transaction.

ROLLBACK-: roll back the transaction if there any error occur.

SAVEPOINT-: creating save point to roll back the transaction making points in groups.

.mdf file-: An MDF file is primary database file in SQL Server. This file created whenever we create a new database file. This file hold the start-up information of database and points other files of databases. For each database in SQL Server, there is an MDF file is created. The corruption can only be solved using the mdf repair tool

Location:

C:\ProgramFiles\MicrosoftSQLServer\MSSQL10_50.SQLEXPRESS\MSSQL\DATA.

.ndf file-: An NDF file is Secondary optional storage file used to store the data when the size of MDF file exceed then its limit. With the help of this file, we can extend the size of out database. An NDF file store the single file data in different disk drive across multiple places.

Location:

C:\ProgramFiles\MicrosoftSQLServer\MSSQL10.MSSQLSERVER\MSSQL\DATA

.ldf file-: A transaction is changes made against the database. A transaction is the smallest unit of task or change in the database, cannot be further divided. To store all these transaction changes SQL Server store a log file knows as LDF file. A .ldf extension file created for each database to store all the changes of the database. These files are used to take backup or recovery of the transaction in the database if accidentally data is deleted or lost.

Location:

Program Files\Microsoft SQL Server\MSSQL.n\MSSQL\LOG\ERRORLOG

bak file: A BAK file use to store the backup of a database. The extension used for these files is .bak file.These files are used to recover the data during restoration process of the database. User can take backup of their database data by restore option in SQL Server application

.sql file: A SQL script is a set of SQL commands saved in SQL Scripts files. A SQL script contain one or more SQL statements or PL/SQL blocks. You can use SQL Scripts to create, edit, view, run, and delete script files. SQL scripts are easily read or processed or edited by SQL Compatible database program.

Power issues: During accidental Power failures, an MDF file can be damaged or corrupted. Data can be lost due to power failure and not completely stored in storage device.

Rebooting: Suddenly rebooting of SQL Server also result in corruption of file.

Accidental delete record: A data can be accidentally lost due to many reason Hard drive crash, malware attack etc.

Driver and Controller issues. Sometimes many counterfeit driver or Controller can damage the .mdf and other associated file.

To solve the issue related to the backup of the database file, we can use BKF files. But due to hardware or software related matter, a .bak file is not generated properly.Even sometimes the backup file is also corrupted. In this case, you can use MDF Repair tool to access the .bkf file.
