## databases

The product's databases are installed on a Database Server or a Primary Server and run in the background of your system. To connect to these databases, uses the SQL Server instance you created when you installed the product or configured SQL Server.

For information on managing these databases in the product, see "" on page 1.

#### Microsoft SQL Server database

Microsoft SQL Server is the database engine that manages the product's databases: the ION database (), the Network Configuration database (), the System Events database (), and the Application Modules database (ApplicationModules). The product uses a SQL Server instance to connect to the databases. The instance is created either when you install a supported SQL Server Standard or Enterprise edition, or when you install a supported edition of SQL Server 2012 Express, SP1 with the product. You can also specify a pre-existing instance during the installation process.

#### The Network Configuration database

The Network Configuration database (“”) stores information about your network topology — the network connections, computers and every connected device, including dialout modems. This information is used by the communications services (for example, , ) and other software components to manage data and control requests to and from the devices and the other product components (that is, , ).

#### The System Events database

The System Events database (“”) stores data about events that occur during the operation of the components. For example, the event details about the communication service’s interactions with devices, details about controls initiated through , and general or alarm level events that occur in the are all inserted into the System Events database. These can then be viewed when you click the System Log Events icon in or through access to the database using (Event Log Viewer).

is not backed up. Some contents of the System Log — System Events with a priority of 192 or greater — are automatically inserted into the database on a regular basis and can be viewed in .
