Another approach to hardware support for database management was ICL's CAFS accelerator, a hardware disk controller with programmable search capabilities. In the long term, these efforts were generally unsuccessful because specialized database machines could not keep pace with the rapid development and progress of general-purpose computers. Thus most database systems nowadays are software systems running on general-purpose hardware, using general-purpose computer data storage. However this idea is still pursued for certain applications by some companies like Netezza and Oracle (Exadata).

The predominant educational psychology from the 1750s onward, especially in northern European countries was associationism, the notion that the mind associates or dissociates ideas through repeated routines. In addition to being conducive to Enlightenment ideologies of liberty, self-determination and personal responsibility, it offered a practical theory of the mind that allowed teachers to transform longstanding forms of print and manuscript culture into effective graphic tools of learning for the lower and middle orders of society. Children were taught to memorize facts through oral and graphic methods that originated during the Renaissance.
