SQL Application for Periodic System of Elements
Journal Title: Leonardo Electronic Journal of Practices and Technologies - Year 2004, Vol 3, Issue 4
Abstract
The paper presents SQL power of periodic system using for didactic aim. The article is based on a PHP application developed to present a periodic system in a form, which can be used for answer at different questions, which can be asked related at the structure of elements.
