For those who are interested in the more technical background of the development of DBeasy, there is a sourcecode documentation.
DBeasy sourcecode is documented with phpdoc. Similar to javadoc or doxygen relationships of classes, functions and files are presented, enumerated and commented.
Though the language of the user interface is German, English was used for the sourcecode, filenames and documentation.
