The term 'redundancy' in database terminology refers to the duplication of data within a database. Redundancy occurs when the same piece of data is stored in multiple places. This can lead to issues such as data inconsistency, where one version of the data might be updated while another version remains unchanged. Managing redundancy is an important aspect of database design, as it can help improve data integrity and optimize storage usage by reducing unnecessary duplication.

The other concepts presented do not align with the definition of redundancy. Uniqueness of records pertains to the distinct characteristics of each record, the organization of data refers to the structural arrangement within tables, and the process of deleting obsolete data addresses data maintenance rather than duplication. Understanding redundancy is crucial for database normalization and efficient data management practices.
