 Nested Set is a solution for storing hierarchical data that provides very fast read access. However, updating nested set trees is more costly.
 Therefore this solution is best suited for hierarchies that are much more frequently read than written to. And because of the nature of the web,

 The rootColumnName is the column that is used to differentiate between trees. When you create a new node to insert it into an existing tree you dont need to care about this field. This is done by the nested set implementation. However, when you want to create a new root node you have the option to set the "root_id" manually. The nested set implementation will recognize that. In the same way you can move nodes between different trees without caring about the "root_id". All of this is handled for you.

 After you successfully set up your model as a nested set you can start working with it. Working with Doctrine's nested set implementation is all about 2 classes: Doctrine_Tree_NestedSet and Doctrine_Node_NestedSet. These are nested set implementations of the interfaces Doctrine_Tree_Interface and Doctrine_Node_Interface. Tree objects are bound to your table objects and node objects are bound to your record objects. This looks as follows:

 getDescendants() and getAncestors() both accept a parameter that you can use to specify the "depth" of the resulting branch. For example getDescendants(1) retrieves only the direct descendants (the descendants that are 1 level below, that's the same as getChildren()). In the same fashion getAncestors(1) would only retrieve the direct ancestor (the parent), etc. getAncestors() can be very useful to efficiently determine the path of this node up to the root node or up to some specific ancestor (i.e. to construct a breadcrumb navigation).

 If you're a demanding software developer this question may already have come into your mind: "How do i fetch a tree/branch with related data?". Simple example: You want to display a tree of categories, but you also want to display some related data of each category, let's say some details of the hottest product in that category. Fetching the tree as seen in the previous sections and simply accessing the relations while iterating over the tree is possible but produces a lot of unnecessary database queries. Luckily, Doctrine_Query and some flexibility in the nested set implementation have come to your rescue. The nested set implementation uses Doctrine_Query objects for all it's database work. By giving you access to the base query object of the nested set implementation you can unleash the full power of Doctrine_Query while using your nested set. Take a look at the following code snippet:
