Links to Wikipedia

The links to Wikipedia for both Primary Key (which redirects to Unique key) and Foreign key could be cleaned up to look nice. However, the target articles are tagged for clean-up in Wikipedia and there are also tags in those articles suggesting that they may also be too technical. Would be better to have the SAS version of these indexing concepts on the sasCommunity wiki? With links in those article to relevant Wikipedia articles? That way we can get technical here and allow Wikipedia to become less technical if it wants to. Also, we could then be certain that the terms Primary Key, Unique Key, and Foreign Key meant what we think they should, rather than having to cope with some Wikipedia editor deciding to simplify and condense a whole lot of related but distinct terms into a single "encyclopedic" article about database indexing. - Cameron 22:01, 11 June 2013 (EDT)
