The eobjects.org MetaModel is a project created for maximum reuse of a SQL-compliant domain model of the database domain. The MetaModel is a model that contains classes that represent the structure of a database (schemas, tables, column, relationships) and interaction with the database (queries) in a SQL/LINQ-like way. In short, it is a model for modelling data in databases and other datastores. With MetaModel you can query different datastores like databases, CSV files, Excel spreadsheets, MS Access files, and XML files using the same approach and the same domain model.
The adventure PHP framework (APF) is a utility to implement object oriented and generic PHP Web applications. It allows the developer to create programs in compliance with approved software design patterns, and the code base already has answers to many everyday problems. The framework cannot be described as an application that only has to be configured, but rather as a technical basis and design guide for the design of software. Further, it introduced many concepts and efficiency tools already well known in the Java community.
Keystone is a cross-platform, object oriented application framework which allows applications to be written to build on the target platforms of GNU/Linux and Win32 without modification of their source. Keystone implements several modern Web standards, including SVG graphics and the XUL user interface description language.
Blackbird is the first enterprise service bus (ESB) for PHP developers. It provides a range of services, including managing configuration data, connections to message queues, databases, and other applications, and many more features. This makes it possible to very rapidly develop message-based applications and/or integration layers.
A microcall is an XML-dialect used to communicate between a client and a server in a standard and easy-to-use way. The client part is (usually) implemented in Java and consists of a simple POJO that can understand the XML messages returned by the server response to a given call. The server part is only responsible for returning standard and correct messages in response to a given call. The server usually does a lot of work when it receives a call, but from the client standpoint, the server only returns a message explaining the result of the call.
Hydrate is a Java mapping tool that lets you lay an object model over relational and XML data and move information quickly and efficiently between these three representations. Its strength lies in working with existing relational or XML databases, over whose schemas you have little or no control. Through Hydrate, you can perform complex calculations and reporting that are best expressed in high-level problem domain modelling offered by an object-oriented language. Hydrate solves real-world problems in a practical way, is flexible, robust, and fast.
Pustefix is a Web application framework that features an XML/XSLT-based view generation and a clean MVC architecture of the backend system. The frontend can be built with the help of XSLT templates and can include parts containing HTML or XML code that is transformed, creating the final HTML output. The backend allows for the creation of reusable handler classes, which can be aggregated into complete pages. These handlers get their input in the form of real Java objects that are already assembled and checked against user defined rules by the framework.
QOF (Query Object Framework), provides a set of C Language utilities for performing generic structured complex queries on a set of data held by a set of C/C++ objects. This framework is unique in that it does not require SQL or any database at all to perform the query. Thus, it allows programmers to add query support to their applications without having to hook into an SQL database.
