You can catalog, document, and query live data from SQL Server by configuring a virtual connection to it. With a virtual connection, your data stays where it is--it is not hosted on data.world--so all actions using it are always run against current data.
When connecting your data systems to data.world, often your system or firewall may have a network policy that only allows access from specific IP addresses--your allowlist. In those cases, you must add data.world to your network policy IP allowlist.
Allow the following IP addresses:
52.3.83.134
52.205.195.10
52.205.207.86
If you are on your organization's home page select Connection Manager. Otherwise go to the integration page (https://data.world/integrations/microsoft-sql-server) and click Enable integration to set up a connection.
When you create a connection to use with a data source you are asked to set the owner of the connection. By default, if you are in organization then your organization is the owner of the connection. However, you can also set yourself as the owner making it a personal connection.
There are two compelling reasons for having most connections owned by an organization:
There is no loss of access to data when an employee leaves and their account is deactivated.
Federation across data sources is faster and more efficient if it uses the same connection.
Organizational-level connections are shared between admins of the organization and can be used by by all of them to create new live tables. Non-administrator users can only query and preview existing live tables.
Note
Organization-owned connections can only be used to add data to datasets owned by that organization. If you are in organizations A and B, you cannot add data to a dataset owned by B using a connection owned by A.
With a personal connection, only the connection owner may create new live tables with the connection, and other members of the organization can query and preview live tables.
In order to create a virtual connection to SQL Server you will use the following parameters:
Host/IP: the url for your database
Port (optional): use if you connect through a special port
Database (optional): You can specify it here or you can choose from a dropdown list when you create a dataset
Connection username: Your username for your data source
Connection password: Your password for your data source
Choose a Connection owner (yourself or your organization) and set the Display name for your connection. The display name is the name everyone in your organization will see for the connection. Then enter your user credential information into the dialog screen:
Click Test SQL Server configuration to make sure it works, and then save it by selecting Configure.
After your connection is configured you can use it anytime you select Add data:
Choose the connection you want to use from My data sources:
Go to the integration page (easily found under My integrations on our Integrations page) and select Manage:
From here you can edit your current connection or add a new one:
Note
You will need your original credentials (password or key file) to make changes to an existing connection.
When executing queries against virtualized data sources in data.world, we will translate those queries to the proper SQL dialect of the target system and run them on the target system whenever possible.
When functions cannot be translated directly, data.world fetch the necessary data from the target system and execute those functions locally. We refer to those as emulated functions or aggregations below.
Additionally, some functions may not be supported on either the target system or locally - those are noted as unavailable functions below.
