+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.

 - 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.
