Overview- 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.

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 filename extensions in SQL Server for the Primary Data files, Secondary data files, and Log files respectively.

Primary data files( MDF)

An MDF file is the primary database file of MS SQL Server and stored as.MDF extension. Being the primary database, it stores all the user data and other database objects like indices, columns, views, functions, tables, keys, stored procedures, triggers, default values, etc.

Secondary data files (NDF)

An NDF file is the secondary database of MS SQL Server saved as.NDF extension. Since it’s not the primary database, you can create as many NDF files as you want. Its primary function is to spread data across multiple disks.

Log files (LDF)

An LDF file is the LOG file in MS SQL Server saved as.LDF extension. An LDF file is just like a backup for a SQL Server database. It creates the log information of a database, and every database has at least one LOG file. In case of accidental deletion or corruption, the LOG file can be used to restore the corrupted files.
