Simply so, what is an ODBC DSN?

A data source name (DSN) is a data structure that contains the information about a specific database that an Open Database Connectivity ( ODBC ) driver needs in order to connect to it. User and system DSNs are specific to a particular computer, and store DSN information in the registry.

Subsequently, question is, what is DSN connection in SQL Server? To host Helix ALM, Helix ALM License Server, or Surround SCM data in a SQL Server database, you must create an ODBC system data source name (DSN) to store database connection information. Each SQL Server database you create to use with these products requires a unique DSN.

how do I find my DSN?

Click the Windows "Start" button and then click "Control Panel." Click "System and Security." Click "Administrative Tools" in the list of utilities. Double-click the icon labeled "Data Sources (ODBC)." A list of DSNs display. Click the DSN you want to test. Click the "Configure" button on the right side.

How does a DSN work?

Data Source Name (DSN) provides connectivity to a database through an ODBC driver. The DSN contains database name, directory, database driver, UserID, password, and other information. Once you create a DSN for a particular database, you can use the DSN in an application to call information from the database.

What is difference between User DSN and System DSN?

A User DSN is only accessible by the user who created it on the workstation. A System DSN is accessible by any user logging into the workstation. A File DSN is shared between all users that have the same drivers installed. A User or System DSN is recommended for consistent performance when using ODBC.

What is meant by DNS server?

Domain Name Servers (DNS) are the Internet's equivalent of a phone book. They maintain a directory of domain names and translate them to Internet Protocol (IP) addresses. This is necessary because, although domain names are easy for people to remember, computers or machines, access websites based on IP addresses.

What is DSN in connection string?

If you want to use a connection string for connecting to a database, or if your application requires it, you must specify either a DSN (data source name), a File DSN, or a DSN-less connection in the string. A DSN or FILEDSN connection string tells the driver where to find the default connection information.
