In computing, a connection string is a string that specifies information about a data source and the means of connecting to it.

Users of Oracle databases can specify connection strings:

Such connections are called context connections and are set by setting parameter to in the connection string.

The term DSN is sometimes mistakenly used in place of connection string.

A single connection string to the server instructs the Client Application where to find all of the services/web sites that are required to operate.

Applications can reference secure Btrieve data using a URI connection string.

The Connection String is composed of a set of key/value pairs as dictated by the data access interface and data provider being used.

Users can embed connection strings to external data sources in the workbook or save them centrally in a data connection library file.

A connection string typically fully describes a data source, while a DSN typically relies on some external system resources and/or configuration file.

After installation, the application connection string set the SafePeak hostname or server IP as the data source.

This example shows a Postgres connection string for connecting to wikipedia.com with SSL and a connection timeout of 180 seconds:

The connection string may include attributes such as the name of the driver, server and database, as well as security information such as user name and password.

A connection object connects to the data store using its 'Open' method with a connection string which specifies the connection as a list of key value pairs (for example: "").

The mapping is implemented by the that takes a connection string to the server, and can be used to generate a where T is the type to which the database table will be mapped.

Anything using SQL Azure will, of course, need a suitable connection string; these can be generated from the SQL Azure Web front-end.

Before running the package, the tool may be instructed to apply configuration information, which will allow the same package to be reused with slightly different parameters, including different connection strings for its endpoints.

Connections are built by supplying an underlying driver or provider with a connection string, which is a way of addressing a specific database or server and instance as well as user authentication credentials (for example, ).

A connection string change allows connection to Firebird, IBM DB2, Informix, Ingres, Microsoft SQL Server, MySQL, Oracle, PostgreSQL, and Google App Engine (GAE) with some caveats.
