Advanced Usage by Data Source Type

The topics in this section provide more advanced GDI usage information by including descriptions for all of the query options for each type of supported data source.

Although connections to data sources can be made directly in GDI queries. Creating the connection in Graph Studio prior to writing queries enables your organization to get an overview of the sources that are in use or available to use. Connecting to a source also gives a sample view of the data to be onboarded (except for JSON and XML sources). And, for sources that require input of sensitive connection and authorization information, connecting the sources to Graph Studio allows you to later hide that sensitive information (through the use of a Query Context) from any queries that are generated for that source. See Adding Data Sources for instructions on connecting to sources.

Rather than manually writing complex queries, you can use the GDI to automatically generate graphs and ontologies by including a few key statements in a relatively simple query. For information, see Onboarding Data with a Direct Load Step.
