34 Provide versioned, clustered, flexible, distributed, multi-dimensional
35 data storage engine for the [[http://www2.svjatoslav.eu/gitbrowse/sixth/doc/index.html][Sixth computation engine]].
37 + Speaking of traditional relational database and object oriented
38 business applications:
39 + I hate object-relational impedance mismatch.
41 + I don't like to convert data between persistent database and
42 runtime objects for every transaction. How about creating united
43 database/computation engine instead to:
44 + Eliminate constant moving and converting of data between 2 systems.
45 + Abstract away difference between RAM VS persistent storage. Let
46 the system decide at runtime which data to keep in what kind of
50 + Relational databases:
52 + Indexable / Quickly searchable.
54 + Git (version control system)
56 + Branchable / mergeable.
57 + Transparent cansistency, checksumming and deduplication.

75 ** Distributed computation and data storage
77 :ID: 5d287158-53ea-44a2-a754-dd862366066a
79 Maybe every problem can be translated to geometry (use any shapes and
80 as many dimensions as you need). Solution(s) to such problems would
81 then appear as relatively simple search/comparison/lookup results. As
82 a bonus, such geometrical *data storage* AND *computation* can be
83 naturally made in *parallel* and *distributed*. That's what neurons in
84 the brain appear to be doing ! :) . Learning means building/updating
85 the model (the hard part). Question answering is making (relatively
86 simple) lookups (geometrical queries) against the model.
87 ** Mapping of hyperspace to traditional object-oriented model
89 :ID: a117c11e-97c1-4822-88b2-9fc10f96caec
91 Object oriented programming is inspired by the way human mind
92 operates. It allows programmer to express ideas to computer in a more
95 It is possible to map object model to geometrical hyperspace:
97 + Object is a point in space (universe). Each object member variable
98 translates to its own dimension. That is: if class declares 4
99 variables for an object, then corresponding object can be stored as
100 a single point inside 4 dimensional space. Variable values translate
101 to point coordinates in space. That is: Integer, floating point
102 number and even boolean and string can be translated to linear value
103 that can be used as a coordinate along particular dimension.
105 + Each class declares its own space (universe). All class instances
106 (objects) are points inside that particular universe. References
107 between objects of different types are hyperlinks (portals) between
109 ** Handling of relations

113 Consider we want to create database of books and authors. Book can
114 have multiple authors, and single person can be author for multiple
115 books. It is possible to store how many hours of work each author has
116 contributed to every book, using hyperspace as follows:
118 + Every dimension corresponds to one particular book author. (10
119 authors in the database, would require 10 dimensional space)
120 + Point in space corresponds to one particular book.
121 + Point location along particular (author) dimension corresponds
122 to amount of work contributed by particular author for given
127 + Every dimension corresponds to one particular book.
128 + Point in space corresponds to one particular author in the entire
130 + Point location along particular (book) dimension corresponds to
131 amount of work contributed for book by given author (point).
135 - More or less defined [[id:f6764282-a6f6-44e6-8716-b428074dd093][Vision / goal]].
137 - Collected some [[id:d2375acc-af14-4f18-8ad0-7949501178c5][ideas]].
139 - Implemented very simple persistent key-value map.
140 - Long term goal is to use it as a backing storage engine and
141 implement more advanced features on top of this.

147 machine reasoning to simplify data processing challenges for AI
