The Database activity package enables the user to connect to a database and perform an entire palette of actions within it, such as executing transactions or queries and non queries. It can be used to connect to a large selection of databases, such as `SQL Server`, `Oracle`, `DB2`, and others, either directly or via ODBC / OLE DB. 
:::note
The OLE DB connectivity method is not supported on Linux machines.

The [Start Transaction](https://docs.uipath.com/activities/other/latest/developer/database-transaction) activity is a container designed to enable the user to connect to a database, perform multiple actions and then disconnect.

The [Connect](https://docs.uipath.com/activities/other/latest/developer/database-connect) and [Disconnect](https://docs.uipath.com/activities/other/latest/developer/database-disconnect) activities can also be used to connect to a database and consequently disconnect, performing any desired actions with individual connections.

The connection process works based on the usage of a `DatabaseConnection` variable. It is unique for each database you connect to and, once obtained, it can be subsequently used throughout your automation project for connecting to the said database. 
:::note
Windows projects require having the 64-bit driver installed on the machine to establish a database connection.
