JQUERY - jQuery is a cross-platform JavaScript library designed to simplify the client-side scripting of HTML. jQuery is the most popular JavaScript library in use today, with installation on 65% of the top 10 million highest-trafficked sites on the Web. jQuery is free, open-source software licensed under the MIT License.

AJAX - Ajax is a client-side script that communicates to and from a server/database without the need for a postback or a complete page refresh. The best definition I've read for Ajax is “the method of exchanging data with a server, and updating parts of a web page – without reloading the entire page.”

PHP - PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.

GIT - Git was created by Linus Torvalds in 2005 for development of the Linux kernel, with other kernel developers contributing to its initial development.

J2ME - J2ME (Java 2 Platform, Micro Edition) is a technology that allows programmers to use the Java programming language and related tools to develop programs for mobile wireless information devices such as cellular phones and personal digital assistants (PDAs).

J2EE - J2EE is a platform-independent, Java-centric environment from Sun for developing, building and deploying Web-based enterprise applications online. The J2EE platform consists of a set of services, APIs, and protocols that provide the functionality for developing multitiered, Web-based applications.



WEB SERVICES

What is Web Service?

A web service is a standard for exchanging information between different types of applications irrespective of language and platform. For example, an android application can interact with java or .net application using web services.

JSON - JSON stands for JavaScript Object Notation.It is an independent data exchange format and is the best alternative for XML.

REST - Representational State Transfer (REST) is an architectural style for building web services. REST requests are made over HTTP using the same HTTP verbs that web browsers use to retrieve web pages and to send data to servers. The verbs are:

• GET – this operation is used to retrieve data from the web service.
• POST – this operation is used to create a new item of data on the web service.
• PUT – this operation is used to update an item of data on the web service.
• PATCH – this operation is used to update an item of data on the web service by describing a set of instructions about how the item should be modified. This verb is not used in the sample application.
• DELETE – this operation is used to delete an item of data on the web service.

Web service APIs that adhere to REST are called RESTful APIs, and are defined using:

• A base URI. 
• HTTP methods, such as GET, POST, PUT, PATCH, or DELETE. 
• A media type for the data, such as JavaScript Object Notation (JSON).

The simplicity of REST has helped make it the primary method for accessing web services in mobile applications.

SOAP - Web services are of two kinds: Simple Object Access Protocol (SOAP) and Representational State Transfer (REST). SOAP defines a standard communication protocol (set of rules) specification for XML-based message exchange. SOAP uses different transport protocols, such as HTTP and SMTP.


XML - XML stands for Extensible Mark-up Language.XML is a very popular format and commonly used for sharing data on the internet. This chapter explains how to parse the XML file and extract necessary information from it. Android provides three types of XML parsers which are DOM,SAX and XMLPullParser.



DATABASE

MySQL - This is very useful in case you have a webserver, and you want to access its data on your android application.MYSQL is used as a database at the webserver and PHP is used to fetch data from the database.

SQLite - SQLite is a opensource SQL database that stores data to a text file on a device. Android comes in with built in SQLite database implementation. SQLite supports all the relational database features.

Web programming are XML, HTML, JavaScript, Perl 5 and PHP.
