PERL

• Perl is a Practical Extraction and Report Language freely available for Unix, MVS, VMS, MS/DOS, Macintosh, OS/2, Amiga, Win NT and other operating systems. Main distribution point of Perl is the Comprehensive Perl Archive Network or CPAN.
• The applications of Perl are enormous and by checking out the Perl Online Manual site lot of information about Perl and its applications is possible.... starting with its Text manipulation features to programming World Wide Web Electronic forms and generally as a Gateway between systems, databases, and users.
• Perl is an Interpreted script, instead of a compiled program. Possible to make changes and run the script immediately afterward. A Perl script is a text file that is parsed and executed line by line by Perl. It usually ends in a ". pl".
• Perl 5 brings object-oriented capabilities, more data structures, new standard interfaces to system and database functions, and handy new extensions to Perl for windowing, graphics, and database work.
• Here in this tutorial we will work with Perl for Unix. Perl for Windows is available freely and the downloaded file usually a zip file needs to be unzipped. After this the path to the Perl Interpreter has to be set.   More>>

CGI

• The Common Gateway Interface (CGI) , or CGI, perimits interactivity between a client and a host operating system through a World Wide Web via the Hyper Text Transfer Protocol(HTTP). It is a standard for interfacing external applications with information servers, such as HTTP or Web servers. A plain HTML document that the Web server retrieves is static, which means it exists in a constant state: a text file that doesn't change. A CGI program, on the other hand, is executed in real-time, so that it can output dynamic information.
• CGI programs need to reside in a special directory called /cgi-bin, so that the Web server knows to execute the program rather than just display it to the browser.
• CGI is not a language. It's a simple protocol that can be used to communicate between Web forms and your program running on the server. A CGI program preferably a script can be written in any language that that can read STDIN, write to STDOUT, read environment variables and allows it to be executed on the system, such as:
  C/C++ Fortran PERL TCL Any Unix shell Visual Basic AppleScript
• If you use a programming language like C or Fortran, you must compile the program before it is run and copy the executable to the /cgi-bin directory. If, you use one of the scripting languages, such as PERL, TCL, or a Unix shell, the script itself only needs to reside in the /cgi-bin directory. More>>

DHTML

• DHTML is the combination of several built-in browser features in fourth generation browsers that enable a web page to be more dynamic.
• DHTML is NOT a scripting language (like JavaScript), but a browser feature- or enhancement- that makes the browser dynamic
• It uses a host of different technologies - JavaScript, VBScript, the Document Object Model (DOM), layers, cascading stylesheets - to create HTML that can change even after a page has been loaded into a browser.
• It is considered to be made up of HTML, Cascading Style Sheets (CSS) ,Scripting language (Javascript, Jscript, VBscript...).All three of these components are linked via Document Object Model (DOM).DOM is the interface that allows scripting languages to access the content, style, and structure of the web documents and change them dynamically.                                                                                                                          [PPT][Examples]

MYSQL

• MySQL is a database management system.
  A database is a structured collection of data. It may be anything from a simple shopping list to a picture gallery or thevast amounts of information in a corporate network. To add, access, and process data stored in a computer database, you need a database management system such as MySQL. Since computers are very good at handling large amounts of data, database management plays a central role in computing, as stand-alone utilities, or as parts of other applications.
  
• MySQL is a relational database management system.
  A relational database stores data in separate tables rather than putting all the data in one big storeroom. This adds speed and flexibility. The tables are linked by defined relations making it possible to combine data from several tables on request. The SQL part of MySQL stands for "Structured Query Language" - the most common standardized language used to access databases.
  
• MySQL is Open Source Software.
  Open source means that it is possible for anyone to use and modify. Anybody can download MySQL from the Internet and use it without paying anything. Anybody so inclined can study the source code and change it to fit their needs. MySQL uses the GPL (GNU General Public License) http://www.gnu.org, to define what you may and may not do with the software in different situations. If you feel uncomfortable with the GPL or need to embed MySQL into a commercial application you can buy a commercially licensed version from us. More>>

PHP

• PHP, which stands 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. Its syntax draws upon C, Java, and Perl, and is easy to learn. The main goal of the language is to allow web developers to write dynamically generated webpages quickly, but you can do much more with PHP.
• This manual consists primarily of a function reference, but also contains a language reference, explanations of some of PHP's major features, and other supplemental information.
• Example 1-1. An introductory example
  <html>
  <head>
  <title>Example</title>
  </head>
  <body>
  <?php echo "Hi, I'm a PHP script!"; ?>
  </body>
  </html>                                                                                                                                             More>>

CYBERSPACE

Introduction

• Cyberspace is a virtual space encompassing hundreds of millions of "Web pages", linked one to another through "hypertext" links and accessible from any computer connected to Internet. It is a domain of words, images and sounds, through which one may navigate by means of a mouse and a computer. Cyberspace already has its architects and its monuments. It is built from basic materials with specific tools. It is organized according to laws and rules.
• This Package is designed to help those in the South or in the East, who are further away, with weaker telecommunication infrastructure or older computers. Among those targeted are the users who share access in cybercafés, clubs, university multimedia centres and cultural centres.
• The Package aims to bring together and organize the most important information*, tools, laws and regulations of cyberspace as well as analyses presenting the social and economic stakes of the information society for developing countries.More>>

• This Package provides some of the important information on Legal issues, Societal issues - the stakes and on the technologies of the Internet.

IMARK: Management of Electronic Documents

Introduction

• The Information Management Resource Kit (IMARK) is being developed by the Food and Agriculture Organization of the United Nations in partnership with other agencies and institutions with the common goal of mobilizing and building upon existing resources to create a comprehensive suite of distance learning resources for information management and exchange.
• Each IMARK Module offers a detailed curriculum focused on specific areas of information management including: electronic documents and images, tabular and spatial data, electronic networking and information management strategies.
• The Module deals with the collection, archiving, management and dissemination of electronic documents and associated images.
• The lessons are delivered using an interactive, self-paced learning environment.Each lesson achieves a specific set of learning objectives, using interactive step-by-step instruction and exercises which help reinforce what is being taught.

Table of Contents

• The total curriculum consists of 27 lessons, of approximately 30 to 45 minutes duration each, grouped into six units, for a total of about 13 to 20 hours of self-paced instruction. Each lesson includes a list of relevant resources and additional reading. Learners can consult a glossary specific to the Module, and search within the course materials for specific terms. A series of non-proprietary software applications and methodological guides are also provided.
