Io is a small, prototype-based programming language. The ideas in Io are mostly inspired by Smalltalk (all values are objects, all messages are dynamic), Self (prototype-based), NewtonScript (differential inheritance), Act1 (actors and futures for concurrency), LISP (code is a runtime inspectable/modifiable tree) and Lua (small, embeddable).

StarUML is a free, Windows-based UML tool used for creating diagrams related to application design. There are many different kinds of diagrams that UML support, but our focus here will be on Class Diagrams. Class diagrams represent the structure of a collection of classes by showing both how they're defined (inheritance hierarchy) and how they relate to one another (associations).

Consider a tree. A tree is made up of many parts, such as the roots that reside in the ground, the trunk, bark, branches, leaves, etc. Essentially inheritance is a connection between a child and its parent.
In this installment of The busy Java developer's guide to db4o, discover the surprising ease (and power) of using inheritance as a core feature when creating queries in db4o.
Préparez-vous, dans 10 mois on pourra fêter l'incapacité d'un navigateur basé sur Gecko (Mozilla, Firefox, Camino...) à respecter l'attribut 'align' sur un 'col'. Et ils se disent les champions du pragmatisme.
Whoever made its get*() methods final and the trace property private did not thought any second about how exceptions may be used or that people need to implement their own stack trace handling.
What will we cover? * What is an object? * What is a Class? * What are polymorphism and inheritance? * Creating, Storing and using objects
Prototype-based programming is a style of object-oriented programming in which classes are not present, and behaviour reuse (known as inheritance in class-based languages) is accomplished through a process of cloning existing objects which serve as prototypes. This model is also known as class-less, or prototype-oriented, or instance-based programming.

This article is intended for experienced PHP programmers with at least a basic understanding of objects, classes and inheritance. The typical reader will want to learn more about techniques for deploying components in object-oriented systems.
Mako is a template library written in Python. It provides a familiar, non-XML syntax which compiles into Python modules for maximum performance. Mako's syntax and API borrows from the best ideas of many others, including Django templates, Cheetah, Myghty, and Genshi. Conceptually, Mako is an embedded Python (i.e. Python Server Page) language, which refines the familiar ideas of componentized layout and inheritance to produce one of the most straightforward and flexible models available, while also maintaining close ties to Python calling and scoping semantics.

In this article I will show how to generate dynamic XML documents with Object-Oriented PHP. Before I get started, let's get right to the heart of this functionality. Although the code may look fancy, being packaged up inside objects and inheritance, the key elements of this functionality rest in the the mysql_list_fields() and mysql_num_fields() functions.

Hibernate is a powerful, high performance object/relational persistence and query service. Hibernate lets you develop persistent classes following object-oriented idiom - including association, inheritance, polymorphism, composition, and collections. Hibernate allows you to express queries in its own portable SQL extension (HQL), as well as in native SQL, or with an object-oriented Criteria and Example API.Unlike many other persistence solutions, Hibernate does not hide the power of SQL from you and guarantees that your investment in relational technology and knowledge is as valid as always. The LGPL open source license allows the use of Hibernate and NHibernate in open source and commercial projects.Hibernate is a Professional Open Source project and a critical component of the JBoss Enterprise Middleware System (JEMS) suite of products. JBoss, a division of Red Hat, offers a range of 24x7 Professional Support, Consulting, and Training services to assist you with Hibernate.
This article concisely explores the mechanism in depth, including flaws in other approaches, internal Javascript algorithms, proper OOP data encapsulation with default constructors, and an optimized inheritance declaration syntax with both Object and Function prototype convenience methods.
Propel provides basic support for implementing object-oriented inheritance (subclassing) your object model.
