Languages and Software to Be Used

---

Three major technologies will be used in this course:

• LAMP, including Linux, Apache, MySQL, and PHP,


• Android, including Android Studio, Java, and XML, and


• AJAX, including (X)HTML, CSS, HTML DOM, JavaScript, PHP, SQL, and XML.

AJAX (Asynchronous JavaScript and XML)
With AJAX, web applications can send data to and retrieve from a server asynchronously (in the background) without interfering with the display and behavior of the existing page. AJAX is a group of technologies to create asynchronous web applications:

• XHTML and CSS (Cascading Style Sheets) can be used in combination to mark up and style information.


• Dynamic display and interaction use the DOM (Document Object Model), which defines a standard way for accessing and manipulating HTML documents.


• Data interchange and manipulation use XML and XSLT.


• Asynchronous data retrieval uses XMLHttpRequest.
  By using the XMLHttpRequest object, a web developer can change a page with data from the server after the page has loaded.


• JavaScript binds everything together.

The AJAX example below shows how a web page can communicate with a web server online via a standard HTML form:
