After establishing the connection, you are ready to use methods on the Connection object to send requests from the application to operate the database.
If you are familiar with GQL (Graph Query Language) or UQL (Ultipa Query Language), you can execute queries using the gql() or uql() method. For more information, refer to the following:
The driver also provides the following dedicated methods for key database operations:
- Graph
- Schema and Property
- Data Insertion
- Query Acceleration
- HDC Graph and Algorithm
- Process and Job
- Access Control
- Data Export
- Server Statistics
