What Are These Terms Applets And CGI Scripts.

APPLETS, CGI SCRIPTS
Every body know that Web server is a computer which transports web pages. A relational database or simply database is a collection of information stored in tables. A database contains one or more tables. Every table has a name and consists of columns and rows. All lines have their own names. Most ecommerce sites consist of a front end and a back end. Front end consists of that information which is visible to the user and he can interact with the same through some interface.

The back end comprises that information which resides on the server side and is used to create certain dynamic results for the user. It would include different programs or scripts that may be developed in different languages/tools. For an effective e-commerce site there must be a real integration or compatibility between the front end and the back end. We develop our back end mainly for two purposes – for querying with the databases (where we have developed databases) and for the maintenance of state can use different tools (ASP, JSP etc.) for that purpose depending upon their respective advantages /disadvantages. Server side processing can be mainly categorized into four headings -CGI Scripts, Servlets, Server Side Scripts and JDBC/ODBC drivers.
