comment Symbol for None/Null/undefined variables that are not sets
@A.Ellett I don't think OP is asking for a "TeX null" but for a typographical representation of "null". But I agree, either give more context, check How to look up a symbol or identify a math symbol or character?, or just define your symbol to the reader beforehand.

comment Node position based on two nodes
With the positioning library the anchors are set automatically so we can just do below right=0mm and 4mm of <other node>. (Or set node distance=0mm and 4mm and just use below right=of <other node> of course.)

comment Flipping nodes in a pie chart
Instead of manual rotating by either 220 or 220-180 degree, you can just add the option sloped (there's also allow upside down which defaults to false).

comment positioning a node on a path rather than “above” or “below”
@JasonS The manual actually mentions auto=false to deactivate the automatic placement. (I've not tried it.)

comment drawing a line that stops at the edge of a shape
\node at ([shift=(1,1)]C) {Hey!} (or at ($(C)+(1,1)$) with the calc library) or \node[above right=1 and 1 of C]{Hey} (see positioning library) and possibily the on grid option.

comment drawing a line that stops at the edge of a shape
Either add above or anchor=<something> or similar, or place the node before and then connect it. There also might be the possibility to use mark connection node from the decoration.markings library, though I prefer the node placed before.

comment Is it possible to produce data cubes in Latex with reasonable effort?
@Thomas I have edited my answer and added some explanations. I also get rid of paths.rectangle and the coordinates along it (see your \foreach comment before). It was more a remnant of previous approach to that area.

comment Follow up question to data cubes in Latex
The none dash pattern is, well, wrong. What is it supposed to do? It basically defines an infinite amount of infinitesimal short parts. TeXstudio (and Sumatra) seem to ignore this. Adobe trips.

comment I try to draw the figure by using Tikz,but can't
I’d suggest \draw[even odd rule, pattern=north west lines] (0,0) circle [radius=2] circle[radius=1];

It might be appropriate to use \pgfmathtruncatemacro (it doesn't matter in this example, though).

comment Positioning entries in a Venn diagram - edited version
Well, just to calculate the anchor of the node with the angles you provided. The label just adds another node at a parent node (or a parant coordinate). That has nothing to do with the at part of the parent. I advice to read section 17.10 (pp. 239ff) in the PGF manual. Also, the label/pin positioning is not very precise as it snaps to certain places.

comment Positioning entries in a Venn diagram - edited version
Why not \node[anchor=150+180] at (alpha) {$A$};? (alpha is a coordinate so its .150 anchor (any of its anchors) is just the coordinate again.)
