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: "Provider='SQLOLEDB';Data Source='TheSqlServer'; Initial Catalog='Northwind';Integrated Security='SSPI';").
A database connection is a facility in computer science that allows client software to talk to database server software, whether on the same machine or not. A connection is required to send commands and receive answers, usually in the form of a result set. Connections are a key concept in data-centric programming.
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: "Provider='SQLOLEDB';Data Source='TheSqlServer'; Initial Catalog='Northwind';Integrated Security='SSPI';"). [9]
In computing, a connection string is a string that specifies information about a data source and the means of connecting to it. It is passed in code to an underlying driver or provider in order to initiate the connection. Whilst commonly used for a database connection, the data source could also be a spreadsheet or text file.
The term often overlaps with "connection string". Most systems do not make a distinction between DSNs or connection strings and the term can often be used interchangeably. [1] DSN attributes may include, but are not limited to: [2] the name of the data source; the location of the data source; the name of a database driver which can access the ...
When connection pool configurations exceed these limits, issues such as rejected connections, throttling, or degraded performance can occur. Depending on how database limits are applied, overprovisioned connection pools can create significant resource contention as the server struggles to manage excessive simultaneous connections.
Once activated, database security no longer requires that the user has access to the underlying files. In addition, client/server configurations no longer require the use of network shares or mapped drives. Applications can reference secure Btrieve data using a URI connection string.
