What is hierarchical tree?

Maple stores data in units named nodes, which are linked together like the leaves of a tree, i.e., joined by branches, all originating from a common root. This is similar to files and folders on your hard disk. Each node contains an article. An article is similar to a document which can be edited in a word processor. Maple comes with its own powerful built-in word processor which enables you to edit the articles directly.

A tree node can contain many other nodes, which are called child nodes or sub nodes. These child nodes can be hidden from view or shown. Clicking on the minus sign from the left of the tree node will collapse the tree. A node which contains child nodes is also called a subtree.



The possibilities for its use are practically endless: to-do lists, recipes, project notes, personal contacts, bookmark lists, reports, term papers and more...
