# Introduction

Introduction -- Generic tree management, currently supports DB and XML as data sources

## Structures_Tree Description

Provides methods to read and manipulate trees, which are stored in the DB or an XML file. The trees can be stored in the DB either as nested trees. Or as simple trees ('brain dead method'), which use parentId-like structure. Currently XML data can only be read from a file and accessed. The package offers a big number of methods to access and manipulate trees. For example methods like: getRoot, getChild[ren[Ids]], getParent[s[Ids]], getPath[ById] and many more.

Unfortunately, complete documentation is not available at the moment.
