    Skipper is a visualization tool and code/schema generator for PHP ORM frameworks like Doctrine2, Doctrine, Propel, and CakePHP, which are used to create database abstraction layer.[2][3][4][5] Skipper is developed by Czech company Inventic, s.r.o. based in Brno,[2] and was known as ORM Designer prior to rebranding in 2014.[6]

    Overview

    [edit | edit source]
    • Generates visual model from the schema definition files[2][3][4]
    • Repetitive import/export of schema definitions in supported formats (XML, YML, PHP annotations)[2][3][4]
    • Schema definition files are automatically generated from the visual model[2][3][4]
    • Visual representation uses ER diagram extended by concepts of inheritance and many-to-many[2][3][4]
    • Supports customization using .xml configuration files and JavaScript[2][7][8]
    • Does not support direct connections to the database[9]
    • Crude and simplistic visual representation and menus[10]

    Architecture

    [edit | edit source]

    Skipper was built on the Qt framework. Import/export of the schema definitions uses XSL transformations powered by LibXslt library. Imported source files are first converted to XML format: no conversion for XML, simple conversion for YML, creating the Abstract Syntax Tree and its subsequent conversion to XML for PHP annotations. The import/export scripts are configured in JavaScript and can be freely customized.[11]

    History

    [edit | edit source]

    Skipper was created as an internal tool for the web applications developed by Inventic. It was first published as a commercial tool under the name ORM Designer in 2009.[13][14] Application was reworked and optimized in January 2013, and released as ORM Designer 2.[11][15] In May 2013 ORM Designer became part of the South Moravian Innovation Center Incubator program (support program for innovative technological startups).[14][16][17] In June 2014, ORM Designer version 3 was released and rebranded under the name of Skipper[6]
