Not well!! Does this resemble your IT person managing your financial master data? Traditionally, financial data marts and operation data stores are built and managed by IT.

Trees in SQL A set-oriented method for representing trees in SQL that runs orders of magnitude faster than the adjacency list (i.e. child-parent pairs) method. [Ed. note: A follow-up to this article is also available.] The usual example of a tree structure in SQL books is called an and it looks like this:
On its face, the relational database management system would appear to be a very poor tool for representing and manipulating trees. This chapter is designed to accomplish the following things: show you that a row in an SQL database can be thought of as an object show you that a pointer from one object to another can be represented by storing an integer key in a regular database column demonstrate the Oracle tree extensions (CONNECT BY ... PRIOR) show you how to work around the limitations of CONNECT BY with PL/SQL The canonical example of trees in Oracle is the org chart. Representing Trees in Oracle SQL

Whether you want to build your own forum, publish the messages from a mailing list on your Website, or write your own cms: there will be a moment that you’ll want to store hierarchical data in a database. And, unless you’re using a XML-like database, tables aren’t hierarchical; they’re just a flat list. You’ll have to find a way to translate the hierarchy in a flat file. Storing trees is a common problem, with multiple solutions.
