Related Content High Performance Web Sites Google Maps, Yahoo! Mail, Facebook, MySpace, YouTube, and Amazon are examples of Web sites built to scale. They access petabytes of data sending terabits per second to millions of users worldwide. A Conversation with Werner Vogels A Conversation with Werner Vogels Jeff Bezos incorporated the company (as Cadabra) in July 1994 and the site went online as in 1995.[12] The company was renamed after the Amazon River, one of the largest rivers in the world,[12] which in turn was named after the Amazons, the legendary nation of female warriors in Greek mythology. Amazon has separate retail websites for United States, United Kingdom, France, Canada, Germany, Italy, Spain, Australia, Brazil, Japan, China, India and Mexico, with international shipping to certain other countries for some of its products.[13] In 2011, it had professed an intention to launch its websites in Poland,[14] Netherlands, and Sweden, as well.[15] An Austrian website operates as part of the German website.

Characteristics[edit] SOAP can form the foundation layer of a web services protocol stack, providing a basic messaging framework upon which web services can be built. This XML-based protocol consists of three parts: an envelope, which defines what is in the message and how to process it, a set of encoding rules for expressing instances of application-defined datatypes, and a convention for representing procedure calls and responses. SOAP has three major characteristics: extensibility (security and WS-routing are among the extensions under development), neutrality (SOAP can be used over any transport protocol such as HTTP, SMTP, TCP, UDP, or JMS), and independence (SOAP allows for any programming model). SOAP


Model of the systems development life cycle, highlighting the maintenance phase. The systems development life cycle (SDLC), also referred to as the application development life-cycle, is a term used in systems engineering, information systems and software engineering to describe a process for planning, creating, testing, and deploying an information system.[1] The systems development life-cycle concept applies to a range of hardware and software configurations, as a system can be composed of hardware only, software only, or a combination of both.[2] Overview[edit] A systems development life cycle is composed of a number of clearly defined and distinct work phases which are used by systems engineers and systems developers to plan for, design, build, test, and deliver information systems.

Software Architecture & Design Patterns This article reviews some of the architecture Design patterns for Enterprise Applications built using the .NET Platform. Application Architecture: Software Applications come in all shapes and sizes. Based on their design and architecture enterprise applications can be classified into various categories such as: Software Architecture & Design Patterns Software Architecture & Design Patterns
This tutorial discusses the second and third fundamental object oriented programming principles of inheritance and polymorphism. The first fundamental principle, encapsulation, was discussed in the previous tutorial. Inheritance Inheritance is the capability of a class to use the properties and methods of another class while adding its own functionality. An example of where this could be useful is with an employee records system. Java Tutorial 4 - Encapsulation and Classes Java Tutorial 4 - Encapsulation and Classes
Creational Patterns - Factory Pattern Factory of what? Of classes. In simple words, if we have a super class and n sub-classes, and based on data provided, we have to return the object of one of the sub-classes, we use a factory pattern. Let’s take an example to understand this pattern. Example: Let’s suppose an application asks for entering the name and sex of a person.

Web Services Architecture Web Services Architecture B An Overview of Web Services Security Technologies (Non-Normative) This section attempts to provide a non-exhaustive description of current available work around Web services security relevant to the requirements and solutions presented in 3.6 Web Services Security. Note that although these technologies build on existing security technologies, they are relatively new and need to be fully tested in actual deployment scenarios. B.1 XML-Signature and XML-Encryption XML signatures are designed for use in XML transactions. It is a standard that was jointly developed by W3C and the IETF (RFC 2807, RFC 3275).
