This software feature allows for storing a tree structure in a database table.
To use Tree::Numbered::DB, you first need to connect with a database through DBI. After that, you can access the tree object using the 'read' or 'new' methods. Once you have the object, you can make changes to the tree by calling its methods like append().
Tree::Numbered::DB is derived from Tree::Numbered and comes with all its features, with only a few changes to the arguments and methods. However, it offers a distinct advantage by allowing you to modify the relations between the table and the tree by adding or deleting fields on runtime.
The software provides a mechanism for this, which is described in brief, in the package. To learn more about dealing with fields, you can check the documentation for Tree::Numbered. The flexibility offered by this feature comes in handy while working with extensive tables.
In conclusion, if you want to store and manage a tree structure using database tables, then Tree::Numbered::DB is an excellent option. The working example provided in the distribution directory can help you understand its functionality better.
