Because PowerShell needs to be usable as an immediate scripting language by IT professionals who type in commands at a console, there have to be language devices such as aliases that can make for terseness when appropriate. There are several ways of cutting down the verbiage in a script, and being able to specify default values via $PSDefaultParameterValues is one of the more generally useful ones. Michael Sorens explains how it can save you time in your daily work.

Many practical database problems can be tackled more simply and intuitively by graphs or networks, which in this sense are graphs in which attributes can be associated with the nodes and edges. It is a natural way to study relationships within the data. SQL databases aren't the easiest way of doing it, but it makes sense where the scale permits it. Because of the range of graphs and techniques, some Graph theory is unavoidable before you get stuck into the code, and who better to introduce graph databases than Joe Celko?
