To produce a prototype of dynamic content WWW pages using
both XML and database-systems
To produce integrated XML and WWW pages, using a database
All of the main areas have been investigate and have been
proven to work. Flash 5 will read XML and PHP works well
with MySQL. It is likely, though, that a server will have
to be setup on a remote site. This is only likely to cost
around £3/month, and should support MySQL.
This project proposes an approach for developing reconfigurable-Web-content
prototypes. You have to consider that the key to understand and
to integrate reliable and robust dynamic prototypes is to design
The basic idea is that before implementing your components you
have to take into account technologies that are compatible with
most of users and exist to last. For its across-system functionality,
PHP has then been accepted as well as Flash, an authoring tool,
which enhances the interactivity and dynamism of Web pages with
the aid of its integrated language, ActionScript. The concept
of reconfigurable Web content is also inherent in the storage
of data. Assuming that databases have to be across-system such
as the previous scripting languages, the wide range of databases
is reduced at two methods of data storage:
- A new structured file technology, XML
- And a robust and proven-to-work database, MySQL.
Investing these technologies serves to list several assumptions
about implementing methods. In fact, the most common method for
design reuse is the Object-Oriented method. Designing objects
is managing the complexity of your prototypes and splitting your
project into manageable components. This method is relevant for
extracting data from XML documents. Indeed, PHP with its XML handlers
and its capabilities of developing classes enhances the reliability
of your components. As well as the server side language, Macromedia
provides XML objects to evolve Flash movies. In another hand,
an attractive interface is inherent in the Web content that is
displayed, so a meticulous study of what a relevant interface
design is has to be investigated.
To perform the reusable component's study, several prototypes
have to be developed according to the next aims:
- Displaying web content from structured file, XML: objects and
PHP functions are combined to fulfil this component.
- Displaying web content from a database, MySQL: to implement
a component with similar aims that the XML one using only PHP
- Streaming dynamic sound with Flash and XML files: to provide
- A voting system storing users' information and displaying it
back: editing and creating XML files with PHP as middleware and
Flash as client side interface.
While the implementation, components are subject to several evaluations:
- A Human Computer Interface has to satisfy the user's eye.
- Authoring tools or Server side script language: dynamic display
from different locations of the network, client and server side.
- Comparing databases systems and structured files clarifies their
strengths and weakness for a future use.
- Scripts architecture: are Object-Oriented scripts reliable and
- Overhead of display: what is the fastest component, the one
using XML or MySQL?
In spite of the technological challenges dynamic reconfigurable
web content components are capable and operational applications.
They prove to be robust and reliable.
XML is the language of the future, and is the true integrator
of definition languages. It can be used in many applications,
and is portable across systems. XML is similar to HTML, but XML
allows for tags to be defined by the user. An example of an XML
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE questions SYSTEM">
<title>This is the first question</title>
<title>This is the second question</title>
; ; ; ;
An example with an proper questions is:
Source code: Here [This contains
the Flash 5 code required to read an XML file, and display it]
A basic outline of the system is show below. The XML generator
is a basic package which converts a file, such as a spreadsheet
to XML data. This might contain page layout information which
can be used by the WWW page. The XML file is then read by the
Flash component. As much as possible the component will be general-purpose,
and will read its parameters from the XML file. An example of
a component could be for a links page, which contains up-to-the-minute
information. The Flash component then communicates with the WWW
page through the fscommand() function, and calls the dofscommand()
the component using Active X. This will allow the component to
change its operation. For example this might be to change the
language of the text from one language (such as English) to another
(such as French). The Flash component might thus have to read
another XML file for the required information.
