In the context of ABS services, what does "immutable data" refer to?

In the context of ABS services, "immutable data" specifically refers to data that cannot be altered once it has been created. This characteristic is essential for maintaining the integrity and reliability of data over time, as it ensures that once information is recorded, it remains unchanged and can be securely referenced or audited without concerns of manipulation.

Immutable data is particularly valuable in various applications, such as blockchain technology, where preserving the original content is crucial for trust and accountability. By prohibiting alterations, organizations can maintain historical records that reflect accurate information and transactions as they occurred. This capability fosters confidence in data management systems and is a fundamental principle for many modern data storage solutions.

The other options discuss data characteristics that involve change or variability, which do not align with the definition of immutable data.
