Brief of SQL Database
SQL Server is a Microsoft product mainly used to manage and store information. Microsoft SQL Server allows you to store and retrieve a huge amount of data by applying queries to the database. And we all know that Query is nothing but a set of statements which executes specific functions when executed.
Or technically we can say that SQL Server is a Relational Database Management System.
- Reporting services
- Analysis services
- Replication services
- Full-text search services
- Integration services
- Notification services
Though these services are not essential for the operation of database system but they provide value added services on top of the core database management system.
File Formats Of SQL Database
If you have worked with SQL Server, you must have heard the terms MDF, NDF, and LDF already. Those are the frequently used for the Primary Data files, Secondary data files, and Log files respectively.
In SQL Server, data and log information are never stored together in the same file. Moreover, these individual files are used by only one server.
Primary data files( MDF)
A primary data file is the beginning point of the database Every database has one primary data file. Also, all the data in the database objects such as tables, stored procedures, trigger, views etc. are stored in the primary data files only. The most common and recommended file name extension for primary data files is “.mdf”.
Secondary data files(NDF)
You can only have one primary data file for a database and the others file created comes under secondary data files. But it is not necessary to have a secondary data file so some databases do not any secondary data file. It is also possible to have multiple secondary data files for a single database. “.ndf” file extension is usually recommended for secondary data files. It’s also possible for you to store the secondary data file on a separate physical drive.
Log files ( LDF)
Log files in SQL Server databases keep all the log information. That information can be later used to recover and retrieve the database. The size of the log file is determined by the logging level you have set up for your database. There is at least one log file for each database. It is also possible to have more than one log file for one database. The file name extension for log files is “.ldf”.
But unfortunately, these files are prone to corruptions. Corrupt SQL Database is not less any than a nightmare. There is a very high probability that your MDF files may get damaged due to corruption.
