About connectors, data sources, and credentials

In Looker Studio, connecting to your data involves the following components:

• Connectors connect Looker Studio to your underlying data. Connecting to your data creates a data source in Looker Studio.
• Data sources represent a particular instance of a connector: for example, a connection to a specific BigQuery table or query, a Google Analytics property, or a Google Sheet. Data sources let you configure the fields and options provided by the connector used to create that connection instance. In addition, the data source gives you a secure way to share information and insights with report viewers who may not be able to directly access the underlying data.

Connectors are specific to the kind of data that you want to visualize in Looker Studio. For example, Google has built connectors to various Google and non-Google products, including BigQuery, Google Sheets, Google Analytics, and MySQL databases. You can also use connectors built by 3rd party developers to visualize data from a wide variety of non-Google products, such as Bing, Facebook Ads, and Salesforce.

See the list of connectors here.

Data sources can be either embedded or reusable. Reports can include both embedded and reusable data sources.

Data sources that you create while editing a report are embedded in the report. To edit an embedded data source, you do so within that report. Embedded data sources make collaborating on reports and data sources easier. Anyone who can edit the report can also edit the data source as well as modify its connection. When you share or copy the report, any embedded data sources are shared or copied as well.

Data sources that you create from the home page are reusable. You can reuse these data sources in different reports. Reusable data sources let you create and share a consistent data model across your organization. Only people with whom you share the reusable data source can edit it. Only the owner of the data source's credentials can modify the connection.
