+Provide versioned, clustered, flexible, distributed, multi-dimensional
+data storage engine for the [[http://www2.svjatoslav.eu/gitbrowse/sixth/doc/index.html][Sixth computation engine]].

++ Speaking of traditional relational database and object oriented
+ business applications:
+ + I hate object-relational impedance mismatch.
+
+ + I don't like to convert data between persistent database and
+ runtime objects for every transaction. How about creating united
+ database/computation engine instead to:
+ + Eliminate constant moving and converting of data between 2 systems.
+ + Abstract away difference between RAM VS persistent storage. Let
+ the system decide at runtime which data to keep in what kind of
+ memory.
+
+* Inspiration
++ Relational databases:
+ + Transactional.
+ + Indexable / Quickly searchable.
+
++ Git (version control system)
+ + Versionable
+ + Branchable / mergeable.
+ + Transparent cansistency, checksumming and deduplication.

++ Appears to have more than 3D dimensional design. Food for
+ thought...)
+ + https://singularityhub.com/2017/06/21/is-there-a-multidimensional-mathematical-world-hidden-in-the-brains-computation/
+
++ From there come following ideas:
+ + Maybe every problem can be translated to geometry (use any shapes
+ and as many dimensions as you need). Solution(s) to such problems
+ would then appear as relatively simple search/comparison/lookup
+ results. As a bonus, such geometrical *data storage* AND
+ *computation* can be naturally made in *parallel* and
+ *distributed*. That's what neurons in the brain appear to be doing
+ ! :) . Learning means building/updating the model (the hard
+ part). Question answering is making (relatively simple) lookups
+ (geometrical queries) against the model.
+
+ + Mapping of hyperspace to traditional object-oriented programming
+ model:
+ + Object is a point in space (universe). Each object member
+ variable translates to its own dimension. That is: if class
+ declares 4 variables for an object, then corresponding object
+ can be stored as a single point inside 4 dimensional
+ space. Variable values translate to point coordinates in
+ space. That is: Integer, floating point number and even boolean
+ and string can be translated to linear value that can be used as
+ a coordinate along particular dimension.
+
+ + Each class declares its own space (universe). All class
+ instances (objects) are points inside that particular
+ universe. References between objects of different types are
+ hyperlinks (portals) between different universes.

* Current status
+- More or less defined [[id:f6764282-a6f6-44e6-8716-b428074dd093][Vision / goal]].
+
+- Collected some [[id:d2375acc-af14-4f18-8ad0-7949501178c5][ideas]].
+
- Implemented very simple persistent key-value map.
+ - Long term goal is to use it as a backing storage engine and
+ implement more advanced features on top of this.
