JAVASCRIPT

JavaScript is the scripting language of the Web. JavaScript was invented by Brendan Eich at

Netscape (with Navigator 2.0), and has appeared in all browsers since 1996. JavaScript is used

in billions of Web pages to add functionality, validate forms, communicate with the server, and

much more. JavaScript is easy to learn. JavaScript was designed to add interactivity to HTML

pages. JavaScript is usually embedded directly into HTML pages. JavaScript is an interpreted

language (means that scripts execute without preliminary compilation). JavaScript is Case

Sensitive and ignores extra spaces. JavaScript is an Object Oriented Programming (OOP)

language. An OOP language allows you to define your own objects and make your own

variable types.

CSS

CSS stands for Cascading Style Sheets. Styles define how to display HTML elements. Styles

were added to HTML 4.0 to solve a problem. External Style Sheets can save a lot of work.

External Style Sheets are stored in CSS files. CSS defines HOW HTML elements are to be

displayed.

Syntax

A CSS rule has two main parts: a selector, and one or more declarations:

The selector is normally the HTML element you want to style.

Each declaration consists of a property and a value.

The property is the style attribute you want to change. Each property has a value

Types of Style Sheets

A style sheet is a set of stylistic CSS rules that tell a browser how the different parts of a

XHTML document are presented. A style sheet is simply a text file with the file name

extension css.

1. Linked / External

2. Embedded / Internal

3. Inline

Linked / External

Once your <div> tags are in place, add either a class or ID for styling each <div>separately. For

parts of the page that appear only once and form the basic building blocks of the page, web

designers usually use an ID.ID selectors are identified using a hash character (#); class selectors

are identified with a period(.).

<link href=“styles.css" rel="stylesheet" type="text/css" />

Embedded / Internal

<head>

<style type=“text/css”></style>

/* styles go here */

</head>

HTML

HyperTextMarkup Language (HTML) is the main mark-up language for web pages. HTML

elements are the basic building-blocks of webpages.HTML is written in the form of HTML

elements consisting of tags enclosed in angle brackets (like <html>), within the web page

content. The purpose of a web browser is to read HTML documents and compose them into

visible or audible web pages. The browser does not display the HTML tags, but uses the tags to

interpret the content of the page.HTML elements form the building blocks of all websites.

HTML allows images and objects to be embedded and can be used to create interactive forms.

It provides a means to create structured documents by denoting structural semantics for text

such as headings, paragraphs, lists, links, quotes and other items. It can embed scripts in

languages such as JavaScript which affect the behaviour of HTML webpages.

JDBC

JDBC

It is Java application programming interface that allows the Java programmers to access

database management system from Java code. Java Database Connectivity is similar to Open

Database Connectivity (ODBC) which is used for accessing and managing database, but the

difference is that JDBC is designed specifically for Java programs, whereas ODBC is not

depended upon any language.

Connector used in this project is mysql-connector-java-5.0.8-bin. JDBC stands for Java

Database Connectivity, which is a standard Java API for database-independent connectivity

between the Java programming language and a wide range of databases.
