SAMPLE Technology: Metaphoric Conclusions

Let us try to compare SAMPLE-programming technology to some other technologies metaphorically. Programming with complex syntax and semantics resembles driving a car without a control desk. You want to turn --- take a spanner and revolve a special bolt. Need to stop --- take another spanner and turn a gas tap (and what about a brake? find a vice, read its manual, and grip the axle). Such actions have almost nothing common with the country map and the journey plan, although can help in slow, slightly dangerous, but sometimes successful motion.

Situation with complex a-priori syntax and semantics is the same: usually they have nothing common with the problem in question, nor with the intuitive plan of the created program, although can help in slow, slightly dangerous as for errors, but sometimes successful programming.

One needs a steer and a speed lever. To some extent, Prolog is such a tool. Unification (read: steer) and performance strategy (read: lever), its basis, have some similarity to features of human thinking (matching of intuitive images and exhaustion of variants for problem solving).

We go further: we create a country map (samples) from the country pictures (text examples) and allow the user to navigate simply by combining these samples and pictures.
