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. There are presented all queries that are needed to be use for classification of elements after different properties, the database, and user interface design.
