Batch Data Matching Algorithm

The algorithm is as follows:

1. Load the vendor library.
2. Call sdq_init_connector.
3. Call sdq_set_global_parameter.
4. Call sdq_init_session.
5. Call sdq_set_parameter (RECORD_TYPE - Account/Contact/List Mgmt Prospective Contact, BATCH_DATAFLOW_NAME, BATCH_MATCH_MAX_NUM_OF_RECORDS)
6. Query the Siebel database to get the candidate records.

   To get the candidate records, a query against the match key is executed. The match key itself is generated when a record is created, or key fields are updated. Universal Connector supports multiple key generation. For more information about match key generation, see Match Key Generation.

7. Call sdq_set_dedup_candidates. This function is called multiple times to send the list of all the candidate records.
8. Call sdq_start_dedup to start the data matching process.
9. Call sdq_getduplicate. This function is called multiple times to get all the master records and their duplicate records and until the function returns -1 indicating that there are no more records.
10. Call sdq_close_session (int * session_id) while logging out of the current session.
11. Call sdq_close_connector.
