Novice SQL users think "what is the purpose of SQL master database" as they do not have complete knowledge about master database. Instead of thinking more about such queries, you should read out beneath mentioned lines that will help you to perform SQL MDF File Repair accurately and intelligently as well.
Master databases are SQL system databases containing information about running SQL server's configuration. When SQL Server gets installed on the computer system then, it usually produces "master", "model", "msdb", "tempdb resource" and distribution databases by default but, the master database is the entity that must have all SQL databases because, Master database is the backbone of SQL Server and without master records SQL Server cannot be started/executed. The importance of SQL master databases compels users to create replicas of MDF file to use them in bad times.
While master database gets corrupted then, MDF file and NDF files become inaccessible or non-approachable.
