XMLXMLis a markup language similar to HTML. It stands for Extensible Markup Languageand is a W3C recommended specification as a general purpose markup language.This means, unlike other markup languages, XML is not predefined so you mustdefine your own tags. The primary purpose of the language is the sharing ofdata across different systems, such as the Internet. XMLallows you to create your own self descriptive tags, or language that suitsyour application.
XML carries the data and does not present it. It is a publicstandard.Use of XMLWe use it because it offers many advantages to uslike:· Simplicity· Extensibility· Interoperability· Openness· Acore of experienced professionalsSessions:A common type ofclient/server session is a Web or HTTP session. An HTTP session is initiated by a Web browsereach time you visit a website. While each page visitconstitutes an individual session, the term is often used to describe theentire time you spend on the website.

7. XAMPPXAMPPstands for Cross-Platform (X), Apache (A), MySQL (M), PHP (P) and Perl (P). Itis a simple, lightweight Apache distribution that makes it extremely easy fordevelopers to create a local web server for testing purposes.
Itcan also be used to develop documents with LaTeX (via a TeXlipse plug-in) and packages for thesoftware Mathematica. 9.

MySQLMySQL is a Relational DataBase ManagementSystem (RDBMS).RDBMS means R–DB–MS.DB stands forDatabase, a repository for the information store.· The data in a database is organized into tables, and each table isorganized into rows and columns.· Each row in a table is called a record. A record may containsseveral pieces (called fields) of information, and each column in a table isknown as a field.
· MS stands for Management System, thesoftware that allows you to insert, retrieve, modify, or delete records.· R stands for Relational, indicates a particularkind of DBMS that is good at relating information stored in one table toinformation stored in another table by looking for elements common to each ofthem. MySQL operates using client/serverarchitecture in which the server runs on the machine containing the databasesand clients connect to the server over a network. The server operating systemsis usually a Linux (like Redhat 9.
0 etc.) or Windows 2000 operating system.Typically mySQL is supported on Windows XP, Windows Server 2003, Red Hat FedoraLinux, and Debian Linux, and others.
As with any other client/serverapplication, MySQL is a multi-user database system, meaning several users canaccess the database simultaneously. program may contact the serverprogrammatically (meaning a program call the server during execution) ormanually. For example, when you are issuing commands over a telnet session to aMySQL server, you are issuing the requests to the server by typing commands atyour command prompt manually. On the other hand, if you have input some data(say your credit card information on the Internet towards purchase of somegoods) in a form, and the form is processed by using a server side program,then the MySQL server is contacted programmatically. This is often the case incredit card approvals, member subscriptions etc.Some Features ofMySQL· Speed· Ease of use· Less Costly· Query LanguageSupport· Better Capability· Connectivity andsecurity· PortabilityEg. A SQL server: This is an engine whichprovides access to your databases.Client programs for accessing the server: Aprogram allows you to enter queries directly and view results.
