I want some examples. I always get confused, so with some examples I might be able to figure it out better.
Also: Is Eclipse an API or IDE?
This question is related to
api
frameworks
sdk
ide
terminology
In other words...
IDE Even your notepad is an IDE. Every software you write/compile code with is an IDE.
Library A bunch of code which simplifies functions/methods for quick use.
API A programming interface for functions/configuration which you work with, its usage is often documented.
SDK Extras and/or for development/testing purposes.
ToolKit Tiny apps for quick use, often GUIs.
GUI Apps with a graphical interface, requires no knowledge of programming unlike APIs.
Framework Bunch of APIs/huge Library/Snippets wrapped in a namespace/or encapsulated from outer scope for compact handling without conflicts with other code.
MVC
A design pattern separated in Models, Views and Controllers for huge applications. They are not dependent on each other and can be changed/improved/replaced without to take care of other code.
Example:
Car (Model)
The object that is being presented.
Example in IT: A HTML form.
Camera (View)
Something that is able to see the object(car).
Example in IT: Browser that renders a website with the form.
Driver (Controller)
Someone who drives that car.
Example in IT: Functions which handle form data that's being submitted.
Snippets Small codes of only a few lines, may not be even complete but worth for a quick share.
Plug-ins Exclusive functions for specified frameworks/APIs/libraries only.
Add-ons Additional modules or services for specific GUIs.
Consider Android Development:
IDE: Eclipse etc..
Library: android.app.Activity library (Class with all code)
API: Interface basically all functions with which we call
SDK: The Android SDK provides you the API libraries and developer tools necessary to build, test, and debug apps for Android (----tools - DDMS,Emulator ----platforms - Android OS versions, ----platform-tools - ADB, ----API docs)
ToolKit: Could be ADT Bundle
Framework: Big library but more of architecture-oriented
IDE: The MS Office of Programming. It's where you type your code, plus some added features to make you a happier programmer. (e.g. Eclipse, Netbeans). Car body: It's what you really touch, see and work on.
Library: A library is a collection of functions, often grouped into multiple program files, but packaged into a single archive file. This contains programs created by other folks, so that you don't have to reinvent the wheel. (e.g. junit.jar, log4j.jar). A library generally has a key role, but does all of its work behind the scenes, it doesn't have a GUI. Car's engine.
API: The library publisher's documentation. This is how you should use my library. (e.g. log4j API, junit API). Car's user manual - yes, cars do come with one too!
What is a kit? It's a collection of many related items that work together to provide a specific service. When someone says medicine kit, you get everything you need for an emergency: plasters, aspirin, gauze and antiseptic, etc.
SDK: McDonald's Happy Meal. You have everything you need (and don't need) boxed neatly: main course, drink, dessert and a bonus toy. An SDK is a bunch of different software components assembled into a package, such that they're "ready-for-action" right out of the box. It often includes multiple libraries and can, but may not necessarily include plugins, API documentation, even an IDE itself. (e.g. iOS Development Kit).
Toolkit: GUI. GUI. GUI. When you hear 'toolkit' in a programming context, it will often refer to a set of libraries intended for GUI development. Since toolkits are UI-centric, they often come with plugins (or standalone IDE's) that provide screen-painting utilities. (e.g. GWT)
Framework: While not the prevalent notion, a framework can be viewed as a kit. It also has a library (or a collection of libraries that work together) that provides a specific coding structure & pattern (thus the word, framework). (e.g. Spring Framework)
SDK represents to software development kit, and IDE represents to integrated development environment. The IDE is the software or the program is used to write, compile, run, and debug such as Xcode. The SDK is the underlying engine of the IDE, includes all the platform's libraries an app needs to access. It's more basic than an IDE because it doesn't usually have graphical tools.
