Which storage method is not available in AVEVA Historian?

In the context of AVEVA Historian, the ability to efficiently store and manage data is crucial for performance and data retrieval. The linear storage method is not typically employed in AVEVA Historian for a few reasons.

The cyclic storage method allows for data points to be collected in a repeating cycle, which is useful for processes that have a predictable pattern. This can maximize efficiency by ensuring that data storage is both compact and easily retrievable within regular time intervals.

Delta storage captures only the changes (or deltas) between successive data points rather than storing every single point. This method effectively reduces the amount of data stored by concentrating on significant changes, which helps in optimizing storage space and improving retrieval times.

Interpolated storage takes advantage of the knowledge of existing data points to create understood data values at points that were not sampled. This is particularly beneficial in scenarios where you need a comprehensive view of data trends without requiring exhaustive point-by-point data collection.

Linear storage, however, implies a straightforward chronological storage method without the optimizations found in cyclic, delta, or interpolated methods. Since AVEVA Historian aims to handle large volumes of data efficiently and effectively, it opts for methodologies that enhance performance and data integrity, making linear storage an impractical choice
