232 Provide versioned, clustered, flexible, distributed, multi-dimensional

237 <li>Speaking of traditional relational database and object oriented
238 business applications:
240 <li>I hate object-relational impedance mismatch.
243 <li>I don't like to convert data between persistent database and
244 runtime objects for every transaction. How about creating united
245 database/computation engine instead to:
247 <li>Eliminate constant moving and converting of data between 2 systems.
249 <li>Abstract away difference between RAM VS persistent storage. Let
250 the system decide at runtime which data to keep in what kind of

302 <li>From there come following ideas:
304 <li>Maybe every problem can be translated to geometry (use any shapes
305 and as many dimensions as you need). Solution(s) to such problems
306 would then appear as relatively simple search/comparison/lookup
307 results. As a bonus, such geometrical *data storage* AND
308 *computation* can be naturally made in *parallel* and
309 *distributed*. That's what neurons in the brain appear to be doing
310 ! :) . Learning means building/updating the model (the hard
311 part). Question answering is making (relatively simple) lookups
312 (geometrical queries) against the model.
315 <li>Mapping of hyperspace to traditional object-oriented programming
318 <li>Object is a point in space (universe). Each object member
319 variable translates to its own dimension. That is: if class
320 declares 4 variables for an object, then corresponding object
321 can be stored as a single point inside 4 dimensional
322 space. Variable values translate to point coordinates in
323 space. That is: Integer, floating point number and even boolean
324 and string can be translated to linear value that can be used as
325 a coordinate along particular dimension.
328 <li>Each class declares its own space (universe). All class
329 instances (objects) are points inside that particular
330 universe. References between objects of different types are
331 hyperlinks (portals) between different universes.
