sources, such as back-end database and text files that are
stored on a web server or a computer that is accessible to a
web server.
2) ASP.NET enables you to use a set of programming code
called templates to create HTML documents. The advantage
of using template is that you can dynamically insert content
retrieved from data sources, such as back-end database and
text-files, into an HTML document before the HTML
document is displayed to users. Therefore, the information
need not be changed manually as and when the content s
retrieved from data source change.
3) ASP.NET also enables you to separate HTML design from
the data retrieval mechanism. Therefore changing the HTML
deign does not affect the program that retrieve data from the
databases. Similarly, server-side scripting ensures that
changing data sources does not require a change in HTML
documents.
