Data Driven Programming.
Back in the days when real men programmed assembler , and the interwebs were nothing but a wet dream, data-driven programming (DDP) was a big thing. It was one of the most important ways of improving the capabilities of crappy assemblers and compilers and enhancing the performance of slow computers. Imagine doing a sinus calculation on a 1MHz 8-bit Motorola MPU without floating point. Then you would know what one flop is. The solution was to replace the insanely costly math with a sinus table, thus replacing code with data. If you wanted an arcTan function instead, it just required a new table.
