What is Component based Programming?

 branch of software engineering that emphasizes the separation of concerns  it is a reuse-based approach to define, implement and compose loosely coupled independent components  Example: a checkout component, responsible for a users order a card processing component, required by the checkout one to charge the users credit card

 An individual software component is a software package a web service a web resource a module that encapsulates a set of related functions (or data)  With regard to system-wide co-ordination, components communicate with each other via interfaces

In a much simple way… regularly

OOP vs CBP

 OOP Software should be written according to a mental model Modeling of real-world interactions Attempt to create “nouns” and “verbs” to be used in more human readable ways

 CBP (Component Based Programming) Developers should create software by gluing together prefabricated components Modularizing software as software components It is desirable to build complex system by assembling highly cohesive loosely coupled large components

Examples

 Bundles as defined by the OSGi Service PlatformOSGi  Component web platform for modular js, css, and other assets Component  Component Object Model (OCX/ActiveX/COM) and DCOM from Microsoft Component Object ModelDCOMMicrosoft  Enterprise JavaBeans from Sun Microsystems (now Oracle) Enterprise JavaBeansSun MicrosystemsOracle  The System.ComponentModel namespace in Microsoft.NETMicrosoft.NET  Unity3D developed by Unity Technologies Unity3DUnity Technologies  XPCOM from Mozilla Foundation XPCOMMozilla Foundation .NET Remoting from Microsoft.NET RemotingMicrosoft  CORBA and the CORBA Component Model from the Object Management Group CORBACORBA Component ModelObject Management Group

CBP in Progress

 Already exists: Procedure Library  Another way: Through a dependency manager

Omen – a dependency manager for OpenEdge projects  Written in JavaScript to be ran in Node.JS  Available for free in NPM repository  Commands available to: create, install, update or publish project create eclipse project, initalize appserver, generate propath  Private repository for private usage
