What does the term 'coalescing' refer to in the context of using Import Sets?

Automatically merging similar records
Avoiding duplicate records based on specified fields
Transforming data from external sources
Merging multiple data sources into one

The correct answer is: Avoiding duplicate records based on specified fields

In the context of Import Sets within ServiceNow, 'coalescing' specifically refers to the process of avoiding duplicate records based on specified fields. When you configure an Import Set, you can designate certain fields as coalescing fields. This means that if the system encounters a record in the Import Set that has the same value in the designated coalescing field as a record already existing in the target table, it will treat it as a duplicate and will not create a new record. This functionality is crucial for maintaining data integrity and ensuring that the database does not become cluttered with duplicate entries. By allowing ServiceNow to check for existing records based on one or more specified fields, administrators can streamline data management and enhance the accuracy of record-keeping. While other terms like merging records or transforming data imply some aspect of data handling, they do not directly address the specific mechanism of checking for and preventing duplicates based on defined criteria within the context of Import Sets, which is central to the meaning of coalescing.
