Umple can be used for pure UML modeling. Or it can be used to add UML constructs, such as associations and state machines to code written in Java, PHP, or Ruby. It generates code in these languages that can save a large amount of programming effort and result in higher quality. The UmpleOnline tool allows you to edit UML diagrams graphically, and watch the Umple textual code being written in real time. This works the other way too: you can write textual Umple and watch the corresponding UML diagram appear. Umple is being extended to support patterns, tracing, and a variety of other features. Umple is written in itself, which is central to maintaining its quality. Umple can be used today by any programmer or modeler.
Wikitty is a key/value storage and search system. A Java object or a relational table is frozen when writing code or creating a database. To make them evolve, you have to go back into the code, write a migration process, etc. It is also hard to maintain coherent code when you want to develop the same application for similar needs with only small differences. Between the common code and the specific code, it can easily become a real burden. Wikitty tries to answer those problems, bringing a technical solution which is easy to put into place and to use.
MyRad4PHP creates applications on the fly, making a Web application without writing a single line of code. It's inspired by the Entity Framework and Dynamic Data Web sites (Microsoft). The generated application can extend or write code to customize all or some of its functionality. This tool takes a MySQL database and creates a Web application in seconds.
EasyCreator is an extension creator for Joomla!. You start by creating a 'frame' for your extension based on predefined templates for components, modules, plugins, and templates. You can also import existing and installed extensions. It also tries to assist with the creation of multilingual extensions by comparing the existing language file and examining the PHP and XML code for appearences of 'JText::***', then providing an overview of untranslated strings and missing and obsolete translations. An interface for creating config XML files is also provided.
