I'm looking for some advice on how to design a set of tables to represent a
tree style table structure in MySQL.
I have a table that stores a set of items, with each item having a type. The
type of the item belongs to a tree structure of types.
e.g.
Type1 +---- Type2 ---- Type3 +---- Type4

I've just put up a new script on my site:
http://www.mattkruse.com/javascript/mktree/
This script combines javascript and some tricky CSS to create the
easiest-to-implement expandable/collapsable tree I've seen anywhere.
Just define your tree structure in an <UL> list, set its CSS class,
include the .js source file, and that's it! Newer...

I have a VERY LARGE pile of geographic data that I am importing into a database (db of choice is postgres,
though may hop to oracle if necessary). The data is strictly hierarchical - each node has one, and only one
parent. The depth should not exceed 6 or 7 levels. The initial import will have about 6 million leaves, and
3 million branches. I...

It's quite simple to walk to the DOM tree going forward however I can't
figure out a nice clean way to walk the DOM tree in reverse. Checking
previousSibling is not sufficient as the previousSibling could be a
node which has childNodes and therefore the 'true' previousSibling
would be the *deepest* lastChild of the previousSibling...

Problem:
- You have tree structure (XML-like) that you don't want to create
100% in memory, because it just takes too long (for instance, you need
a http request to request the information from a slow distant site).
- But you want to be able to request data from it, such has "give me
all nodes that are under a "//foo/bar" tree, and have a...

I am playing with some trees. In one of the procedures I wrote
for this I am trying to change self to a different tree. A tree
here has four members (val/type/left/right). I found that self = SS
does not work; I have to write self.val = SS.val and the same for
the other members (as shown below). Is there a better way to do this?
In the...

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not.
