-+1 Vision / goal
-++++2 Vision / goal
+-Provide versioned, clustered, flexible, distributed, multi-dimensional -data storage engine for the Sixth computation engine. +Provide hackable, versioned, optimized, distributed, geometrical, +arbitrary dimensional (hypercube based) data storage and computation +engine (as inspired by the brain) for general purpose visual computing +environment called Sixth.
++Because Lisp is hackable self defined programmable programming +language it would be used to provide imperative programming support. +

+-3.1 Brain
+-
-
- I hate object-relational impedance mismatch. - +
- Brain appears to be natural geometrical/parallel data storage and +computational engine: + + +
- Even more awesome is that brain appears to operate and is wired as +arbitrary/variable dimensional structure: +https://singularityhub.com/2017/06/21/is-there-a-multidimensional-mathematical-world-hidden-in-the-brains-computation/ -
- 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: +
- On top of this, this multidimensional space that brain represents
+has dynamic/variable resolution/density:
-
-
- 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. - -

3.2 CM-1 Connection Machine
++++https://en.wikipedia.org/wiki/Connection_Machine +
+ ++Massively parallel (thousands of CPUs) connected via +machine's internal 12-dimensional hypercube network allows to +efficiently simulate arbitrary dimensional hypercube and network +topology between computational units. So that when we are +solving/simulating for example 5 dimensional problem, we can arrange +computational units into virtual 5D network. See: +http://www.mission-base.com/tamiko/theory/cm_txts/di-ch2.html +
+ ++we can pre-distribute data across computation units and perform +parallel geometrical computation. +
+
++4 Reasons for hypercube as a so called first class citizen
+-
-
- Transactional. - -
- Indexable / Quickly searchable. - +
- Hypercube is quite general purpose data structure that naturally +encapsulates wide variety data and problems. + +
- Nicely captures apparent properties of the brain. + +
- Naturally supports distributed and parallel geometrical data storage +and computation. + +
- Dedicated hardware like CM-1 can be built around hypercube concept +that results in data, computation process and hardware, all +beautifully fitting together while complementing each other +strengths. + +
- Hypercube stored data (and computation process) has geometry by its +nature and should fit nicely with "3D first" user interface ideology +of the parent Sixth project.
+- -5 Geometrical computation idea
+++++5.1 Distributed computation and data storage
++++Lots of problems can be translated to geometry (use any shapes and as +many dimensions as you need). Solution(s) to such problems could be +then found via geometrical search/comparison/lookup results. As a +bonus, such geometrical data storage AND computation can be +naturally made in parallel and distributed. +
+ ++Learning means building/updating/re-balancing the model (the hard +part). Question answering is making (relatively simple) lookups +(geometrical queries) against the model. +
++-5.2 Mapping hypercube to object-oriented model and relational database
++++Object oriented programming is inspired by the way human mind +operates. It allows programmer to express ideas to computer in a more +human-like terms. +
+ ++It is actually also possible to map object model and relational +database to geometrical hyperspace: +
-- Git (version control system)
+-
-
- Versionable - -
- Branchable / mergeable. - -
- Transparent cansistency, checksumming and deduplication. - -
- (Git as a database: -https://www.kenneth-truyers.net/2016/10/13/git-nosql-database/ ) - +
- Object or database table row is a point in hypercube arbitrary +dimensional space. Each object member variable or database table +column can be mapped to its own dimension in hypercube. That is: if +class declares 4 variables for an object, then corresponding object +can be stored as a single point inside 4 dimensional +hypercube. Variable values translate to point coordinates in that +hypercube. That is: numbers and string can be translated to linear +value that can be used as a coordinate along particular dimension. + +
- Each object class or database table declares its own hypercube that +contain instances (objects) of that class or rows of a table.
- Brain (appears to have more than 3D dimensional design. Food for -thought…) -

- From there comes following idea: 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. - +

+Points in that cube would nicely capture many to many relations +between authors and the books. +
