AJAX is an approach for building fast, dynamic web pages using existing web standards like XML, JavaScript, CSS, and HTML. It allows updated parts of a web page without reloading the entire page. Frameworks help simplify AJAX development by providing pre-built functions and libraries that handle cross-browser compatibility and other complexities. Direct AJAX frameworks require expertise in HTML, CSS, and JavaScript while indirect frameworks use high-level languages and compilers.

1. AJAX FRAMEWORK Asynchronous JavaScript and XML

2. AJAX is not a new programmng Language.

3. AJAX tells new way to use the existing standards.

4. Ajax Features Platform Independent.

5. Can update parts of a web page, without reloading the whole page.

6. Can able to create fast and dynamic web pages.

7. Reduced loading time and server traffic.

8. STANDARDS AJAX is a combinaton of standards they are: XMLHttpRequest object to exchange data asynchronously with a server

9. JavaScript/DOM to display/interact with the information

10. CSS to style the data

11. XML is often used as the format for transferring data

12. Mechanism

13. FRAMEWORK We need a framework in order to develop a site in a easier way.

14. Fully integrated libraries in a framework so easy to use.

15. The goal of a framework is to provide the Ajax engine and associated server and client-side functions.

16. Types of Frameworks Indirect Ajax frameworks Based on compiler technology, where, instead of writing direct Ajax and Javascript, a high-level language is used instead, along with a compiler that turns the high-level language into JS. Direct Ajax frameworks These frameworks require HTML, CSS and Ajax expertise: a developer is expected to author pages directly in HTML, and framework APIs deal directly with HTML elements.
