Microsoft SQL Server stores two types of data files in default directories on respective systems, which are Master Database Files and Log Database Files, and are abbreviated as MDF and LDF data files; both files are primary in a SQL Server environment.
A database can also have the NDF data file, which is known as a non-primary or secondary data file.
Thus, the precedence of the MDF file is slightly higher than that of NDF, but both play an important role to hold crucial database information.
It is possible to access/open the MDF file either on a same or different computer system using third-party standalone software, and this eliminates the need of having the SQL Server installed & configured on the system and thus, saves time, extra efforts, and money.
