Problem: Winters in Tucson are mild relative to other parts of the United States. Daytime highs in the winter range between 64 and 75 F (18 and 24 C), with overnight lows between 30 and 44 F (1 and 7 C). Tucson typically averages one hard freeze per winter season, with temperatures dipping to the mid or low-20s (7 to 4 C), but this is typically limited to only a very few nights. Although rare, snow has been known to fall in Tucson, usually a light dusting that melts within a day. The most recent snowfall was on February 20, 2013 when 2.0 inches of snow blanketed the city, the largest snowfall since 1987.

Problem: Federalism refers to the mixed or compound mode of government, combining a general government (the central or 'federal' government) with regional governments (provincial, state, Land, cantonal, territorial or other sub-unit governments) in a single political system. Its distinctive feature, exemplified in the founding example of modern federalism of the United States of America under the Constitution of 1789, is a relationship of parity between the two levels of government established. It can thus be defined as a form of government in which there is a division of powers between two levels of government of equal status.

Problem: 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).
Did the CAFS accelerator work as planned?
