| − | == File systems ==
| |
| − |
| |
| − | Currently used tree based and machine local file systems have their limits.
| |
| − | Sorting the same data after multiple hierarchical criteria is impossible.
| |
| − | To give an example: Assume one owns a lot of image-file text-file sets.
| |
| − | The small text files are of high importance (e.g. source code) while the huge images are of relatively low importance (e.g. rendered from source).
| |
| − | Archiving different backup levels (location, redundancy level) for file types of different importance isn't possible with the basic functionalities of tree based file systems.
| |
| − |
| |
| − | File system indexing usage of meta-data and file tagging only mend but do not solve the problem.
| |
| − | Some kind of graph based file systems are needed.
| |
| − | Graph databases (like Neo4j?) are interesting but are only crutches if implemented on top of tree based file systems.
| |
| − |
| |
| − | The limitation to serial access to mass storage disk space (now changing with random access SD drives)
| |
| − | led to the fact that current systems are still hardware near programmed and suffer from a lack of abstraction.
| |
| − | Data must be manually serialized for persistent storage.
| |
| − | Net based services like [http://de.wikipedia.org/wiki/Google_Drive Google drive] and Facebook already emulate this behavior.
| |
| − | Another interesting "on top" approach is [http://www.yesodweb.com/ yesod] with its [http://www.yesodweb.com/book/persistent integrated persistence].

Please don't add technologies where there is no reason to believe that APM will help making them a reality like beaming of humans, warp drives, neutron star physics or the like.
Also the effects of self improving AI that might crop up in the future is of no concern here.
