Model – The Model Database is used as the template for all databases created on the instance.Think of this like the master key to your SQL Server door. This means that SQL Server CANNOT START if the Master database is unavailable. The Master also records the existence of all other databases and the location of those files, and records the initialization information for SQL Server. This information includes logon accounts, linked servers, and system configuration settings. Master – The Master Database records all the system-level information for and instance of SQL Server.For Azure SQL Database, only Master and TembDB apply.
These include Master, Model, MSDB, Resource, and TempDB. System Databases are needed for your SQL Server to operate. What are System Databases and what do they do?
