The basic process of connecting an application to DDS is as follows:
Add DDS driver dependencies: Add DDS driver dependencies to your application, so that you can use the DDS API in your application.
Create DDS client: Create a DDS client using the Client class provided by the DDS driver to connect to DDS. You can specify the address and port number of the DDS server, as well as other authentication information and configuration parameters in the Client constructor.
Get database and collection objects: Use the Client instance to get one or more database objects and use the database objects to get collection objects. You can use the API provided by DDS or the query language of DDS to operate on the documents in the collection.
Perform CRUD operations: Perform CRUD (Create, Read, Update, Delete) operations using collection objects to operate on documents. You can use the API provided by DDS or the query language of DDS to perform query operations.
Create index: Create indexes using collection objects to improve query efficiency and performance. You can create an index using the API provided by DDS or the command line tool of DDS.
Handling errors and exceptions: Handle possible errors and exceptions from DDS operations in your Java applications, so that problems can be detected and fixed in time. You can use try-catch blocks or other error handling mechanisms to catch and handle exceptions.
Close DDS client: Close the connection to DDS in your application, freeing up resources and avoiding connection leaks. You can use the Client's close() method to close the client.
