A logical data model should be used as the blueprint for designing and creating a physical database. But the physical database cannot be created properly with a simple logical to physical mapping.

Logic elements “Exclusive OR” are widely used in a variety of digital devices. However, in some cases, for example, when using increased operating voltages, the use of standard chips is impossible.

Simple logic for nanofluidic computing simulated Date: June 29, ... This hexagonal design would seem to lend itself to pores, ... For example, transition metal ...

When building up a logical design, primary keys should be identified by the actual data points in play. Generated or surrogate keys should be held in abeyance until dealing with the physical design ...

It's time to dig inside to understand how the internal CPU components are designed. We'll discuss transistors, logic gates, power and clock delivery, design synthesis, and verification.

Recently, simple molecular-scale autonomous programmable computers were demonstrated8,9,10,11,12,13,14,15 allowing both input and output information to be in molecular form.
