Nested Sets DB Tree is a class that can be used to manipulate nested sets of database table records that form an hierarchical tree. It provides the means to initialize the record tree, insert record nodes in specific tree positions, retrieve node and parent records, change the position of nodes, and delete record nodes. It uses ANSI SQL statements and the ADODB library to make it work with many database types. Transactions are supported through the ADODB class. The library supports the gettext multilanguage interface.
