In this section, we are going to cover a little bit of groundwork to work with databases. It's a large topic, and many texts are devoted to specific databases and also to accessing databases in general.
It is assumed that the reader has knowledge of these, but here we will briefly introduce some of the concepts that are necessary for the topics in the remaining sections of this chapter.
Packages are being developed and modified at an ever increasing rate, so I urge the reader to review the availability for access to a specific flavor of database, which may not be available at the time of writing, with reference to the standard Julia package list at http://pkg.julialang.org and also by searching at http://github.com.
