- Do any commercial database products support "materialised views"
- i.e. views which are stored partly or fully evaluated, rather than
- being evaluated and discarded on demand? This is a form of "memoising",
- a fairly well-known concept in declarative programming languages.
- It gets tricky when the underlying tables change, and the derived
- view relations may have to be revised.
-
- Also, do any commercial database products provide special storage or
- indexing schemes for unchanging data? I.e. which do not compromise
- towards the need to incrementally change the data, as B-trees etc. do.
