Which term refers to a digital set of records where individual items are linked together in a database?

The term that refers to a digital set of records where individual items are linked together in a database is "blockchaining." Blockchain technology is characterized by a distributed ledger that records transactions across many computers, ensuring that the data cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This ensures both transparency and security since each block contains a cryptographic hash of the previous block, linking them securely.

In contrast, data mining involves the process of discovering patterns and extracting valuable information from large datasets. Artificial intelligence refers to computer systems designed to perform tasks that typically require human intelligence, such as visual perception and decision-making. Data analytics is the process of analyzing raw data to find trends and insights but does not inherently involve the specific linking of records as seen in blockchain technology. Therefore, blockchaining is the most accurate term for describing a linked digital set of records.
