A few days ago I started the development of a new version of my CMS. In that case I also wrote an article about Test Driven Development (TDD) with the Zend Framework. But TDD is another topic. Today I’ll take a closer look on a special technique called “Nested Sets“. Nested sets are used to manage hierarchical data. Instead of walking through the results of a database in an recursive way nested sets providing the possibility to avoid recursive calls. Therefore the response time of an application can be increased extremely by using nested sets.
