Data Source Connections
Designer requires access to your data source to retrieve data for reports, so before you can create reports in Designer, you need to set up a connection to your data source. Connections are defined, named, and stored in the catalog along with the reports and other resources that use them.
Designer supports the following connection types:
| Connection Type | Description |
|---|---|
| JDBC | Connects to a relational database via a JDBC driver. |
| JSON | Connects to a JSON data source and transforms the schemas in the data source to relational schemas. |
| XML | Connects to and transforms an XML hierarchy model to a relational model. |
| SOAP Web Service | Connects to a SOAP Web Service data source by importing a WSDL file. Designer supports SOAP Web Services defined by WSDL 1.1 or WSDL 2.0 as data sources. |
| MongoDB | Connects to a MongoDB database and transforms the collections in the database to relational schemas. |
| Hive | Connects to a relational database stored in a Hive data warehouse via a JDBC connection. |
| Elasticsearch | Connects to an Elasticsearch data source and transforms the schemas in the data source to relational schemas. |
| User Defined | Through the User Data Source API, Designer can access data from an external data source, such as a text file or Excel file, which is not stored in a database or when there is no JDBC driver available. |
| Hierarchical | Designer directly supports XML format data source by wrapping the provided Hierarchical Data Source API. Designer's built-in classes can implement the XML format hierarchical data source interface. You can directly import an XML data source to a catalog. |
