2. History of the WWW
⢠To understand why there became a need
for dynamic websites it helps to know a bit
about the evolution of the World Wide
Web...
3. History of the WWW
⢠The Internet as we know it today was not so much
a single invention, but the culmination of many
different technologies and ďŹelds of research.
⢠We might categorise some of these as:
⢠The physical (network infrastructure)
⢠The logical (information organisation and
transport)
⢠The representatioal (how we represent the
data - usually visual)
⢠The interactive (how we interact with the
data - interfaces)
4. 1958
⢠US Defense Advanced Research Projects
Agency (DARPA) created.
⢠Early research included the development of
robust networking technologies for
connecting remote military assets.
6. 1969
⢠The Advanced Research
Projects Agency Network
(ARPANET), was the world's
ďŹrst operational packet
switching network and the
core network of a set that
came to compose the global
Internet.
7. 1988
⢠US National Science Foundation (NSF)
commissioned the construction of the
NSFNET, a university network backbone.
⢠NSFNET was decommissioned in 1995
when it was replaced by new backbone
networks operated by commercial Internet
Service Providers

9. 1989 - 1990
⢠Tim Berners-Lee, while working
CERN invents the World Wide
Web in a proposal for an
information management system
that presented data in a common
and consistent way.
⢠He creates the HyperText Transfer
Protocol (HTTP), the HyperText
Markup Language (HTML), the ďŹrst
Web browser and the ďŹrst HTTP
server software
10. 6 August 1991
⢠First website goes online.
⢠It deďŹnes DeďŹnes the WorldWideWeb
as âa wide-area hypermedia
information retrieval initiative aiming
to give universal access to a large
universe of documents.â
⢠Makes no mention of anything we
might associate with visual interface
design.
11. An archived copy of the ďŹrst webpage
http://www.w3.org/History/19921103-hypertext/hypertext/WWW/TheProject.html
12. 1992 - 1995
⢠early adopters of the World Wide Web
were primarily university-based scientiďŹc
departments or research laboratories
⢠A turning point was the introduction of
Mosiac - a graphical browser released in
1993
13. ⢠Mosaic was the ďŹrst web browser to display
images inline with text (this was seen as a
huge leap forward at the time)
14. 1992 - 1995
⢠Bandwidth was limited by the network
technologies.
⢠Web began to grow from a few hundred
web pages.
⢠Any sense of web design was severely
limited by these constraints
⢠but, there is a clear trend towards a more
visual, more accessible web
15. Web organisation
⢠In 1993, CERN agrees that anyone can use
the web protocol and code royalty-free
⢠In 1994, Tim Berners-Lee founds the World
Wide Web Consortium (W3C) - the main
international standards organization for the
WWW
16. 1995 - 1998
⢠Commercial interest in capitalising on the
growth of the web (eCommerce)
⢠Increased commercial investment pushed
the technology to a point where there was
a legitimate role for web designers.
⢠Early examples of User Created Content
(UCC) - e.g. GeoCities
17. 1995 - 1998
Browser wars (Netscape vs Internet Explorer)
⢠Feature âarms raceâ
⢠Tables and frames
for more complex
layouts
⢠Animated gifs
⢠Javascript (button
rollovers etc)
⢠...
18. 1995 - 1998
⢠Trend towards advertising a âweb presenceâ rather than offering useful
content or services.
⢠This lead to websites which were stuffed full of attention seeking âbells and
whistlesâ whether they served a purpose or not
⢠Splash pages
⢠Tiled background images
⢠Crazy background and text colour combinations
⢠Animated gifs/ďŹash
⢠Blinking/scrolling/marching ants etc. text effects
⢠http://www.htmlprimer.com/articles/90s-web-design-nostalgic-look-back
⢠http://www.webpagesthatsuck.com/gorgeous-websites-from-the-late-90s-
to-inspire-you-if-you-have-no-taste.html
⢠More often than not this approach distracted from the content and made it
less accessible
20. 1998 - 2000
⢠âTraditionalâ interface design principles start to be seriously
applied to web site designs.
⢠Web development tools like Dreamweaver promote a more
âvisualâ approach/workďŹow to web-interface design.
⢠Content is becoming more important and web-design begins to
focus on servicing that content
⢠But... presentation and content are still combined âspeciďŹed
within html markup. It is not possible to update one
independent of the other.
⢠Website layouts of this period still look square, based mostly on
HTML tables (an abuse of their intended use) and sliced images.
21. 1998 - 2000
"A
 List
 Apart"
 website
 c.
 1998
22. 1999â2001: "Dot-com" boom and
bust
⢠Everyone wanted to jump
on the dot-com bandwagon
at the end of the 20th
Century.
⢠A lot of money was thrown
at entrepreneurs without
solid business plans because
of the novelty of the dot-
com concept, leading to the
tech bubble and subsequent
bust.
23. 2000 - 2004
⢠High-speed Internet connectivity becomes more affordable
⢠Push towards web standards, headed by the World Wide Web
Consortium (W3C)
⢠Continuing trend of more content, more often.
⢠Separation of presentation and content allowing each to be
updated independent of the other.
⢠Cascading Style Sheets (CSS) for presentation
⢠HTML for content
⢠Move away from static web pages towards
dynamic web sites. (more on this later)
25. 2004 â 2007
⢠Web 2.0 era
⢠Web applications vs websites
⢠Highly dynamic
⢠Community oriented
⢠User-contributed multi-media content (lots of it!)
⢠Interactivity and functionality approaching native
desktop applications
⢠Social networking takes off
⢠Purchasing goods and services online via sites like eBay
and Amazon becomes mainstream to the point where it
threatens traditional retailers.
26.
27. 2008 onwards
⢠(almost) real-time content updates
⢠Trend for content to âďŹndâ users (rss feed
subscriptions, twitter updates etc)
⢠Storing personal data âin the cloudâ
⢠Content âmash-upsâ
⢠Embedded widgets, feeds, services etc using
external APIs
⢠Design for multiple devices (especially mobile)
28.
29. So what are the trends?
⢠More content
⢠More frequently (up-to-date and on-
demand)
⢠From more sources (crowd sourcing,
mashups etc)
⢠Moving away from a static web towards a
dynamic web.
30. So what are the trends?
⢠More contributors. As a web designer you need to at least have
an understanding of all these areas and how they ďŹt together.
31. Hypertext Transfer Protocol (HTTP)
⢠HTTP functions as a request-response protocol in the
client-server computing model.
⢠In the most common example the web browser is the client and an
application running on a computer hosting a web site is the server.
⢠The client submits an HTTP request message to the server.
⢠The server returns a response message to the client containing
completion status information about the request and may also
contain requested content in its message body.
35. Advantages of static
websites
⢠Lower entry barrier for development (just
plain old html and css ďŹles).
⢠Simple hosting requirements
⢠Easily cacheable
⢠Can be viewed âofďŹineâ
36. Disadvantages of static
websites
⢠Much less scope for personalisation,
interactivity - any scripting has to be done
client-side.
⢠Every little change/update needs to be
done manually...
37. Some stats
⢠24 hours of video is uploaded to YouTube
every minute. (source)
⢠More than 30 billion pieces of content (web
links, news stories, blog posts, notes, photo
albums, etc.) shared each month in over 70
languages. (source)
⢠50 million tweets are sent per day. (source)
38. Disadvantages of static
websites
⢠Can you even fathom updating this much
content by hand? And these numbers are
growing at an exponential rate.
⢠Fortunately computers are very good at
automating repetitive tasks in a dynamic
way.
39. Dynamic website
⢠Website content is stored in a database
(and/or other external sources) and
assembled with markup and output by a
web server script or application.
40. Advantages of dynamic
website
⢠Content can be updated in a decentralised
way. (a single âwebmasterâ does not have
the sole privilege/responsibility of updating
the website)
⢠Modularisation and reuse of common code
(e.g. headers, menus).
⢠Automation
41. Disadvantages of dynamic website
⢠Higher entry barrier / learning curve for
development
⢠More complex web server requirements
⢠Issues with pages being indexed by search
engines.
⢠Overall the beneďŹts will almost always
outweigh the disadvantages.
