What type of data does a temporal database specifically manage?

• A. Static data that does not change
• B. Data with historical relevance over time
• C. Information that is redundant and non-essential
• D. Real-time streaming data only

Answer: (B)

A temporal database specifically manages data with historical relevance over time. This type of database is designed to handle data that changes and evolves, allowing for the tracking of how data values have changed over specific periods. It enables users to query not only the current state of data but also its historical states, providing a timeline of data changes. Through features like valid time and transaction time, temporal databases help in understanding the data's context and providing insights into trends, changes, and patterns across time. The other types of data mentioned do not align with the purpose of a temporal database. Static data, for instance, remains unchanged and does not reflect the historical aspect that a temporal database captures. Redundant and non-essential information is typically not the focus of a temporal database, which aims to provide meaningful historical context rather than merely storing unnecessary data. Real-time streaming data, while important in many applications, does not specifically relate to the historical tracking of data and often resides in a different data management context. Thus, the emphasis on historical relevance clearly distinguishes option B as the correct choice.
