Final answer:
To minimize duplication of CIs in CMDB tables using import sets, the process of identification and reconciliation should be applied, using transform maps with matching and reconciliation rules to effectively manage the imported data.
Step-by-step explanation:
To minimize the duplication of configuration items (CIs) when populating CMDB tables using import sets, you can apply the process of identification and reconciliation. This process involves identifying existing CIs to prevent the creation of duplicates and reconciling any discrepancies between the data being imported and the existing records. Effective identification and reconciliation entail the use of a predefined set of rules or algorithms that match incoming data against the CMDB, ensuring that only unique and necessary data is added. A transform map is generally used in this process to define the relationships between the fields in the import set and the fields in the existing CMDB table. The matching and reconciliation rules within the transform map handle the complexity of determining whether to insert new records or update existing ones, based on the criteria set forth in these rules.
