Solution

The correct answer to the statement is A. True.

When numerous transformations need to access the same results, creating a table rather than a view can be more efficient for several reasons:

  1. Performance: A table can store the results of transformations physically, which can lead to faster query responses, especially if the data needs to be accessed multiple times. Views, on the other hand, may need to recompute their results every time they are accessed, which can slow down performance.

  2. Indexing: Tables allow for indexing, which can significantly improve the speed of data retrieval. Views do not support indexing directly, which can further impact performance.

  3. Resource Optimization: Creating a table for complex transformations can help reduce the computational load on the database system. This approach can free up resources that would otherwise be used to compute the same view multiple times.

  4. Data Stability: Tables provide a snapshot of data at a specific time, ensuring that all transformations access the same data set, while views may provide different data depending on the underlying tables' current state.

Therefore, when significant access to the results of numerous transformations is required, it is advisable to create a table to enhance performance and resource optimization.
