|
establish systematic reviews and specifically include them in the project schedule, assess the effectiveness of actions taken, identify the status of actions to be taken
|
|
|
http
|
rules that define the interaction between web client and web server- all the allowed commands and responses make up http- an http request takes the form of a url

|
2 tier model
|
web client and web server
|
|
|
3 tiered model
|
connects to web-server port 80
client sends command to web-server requesting a specific application to be activated - Application is executed for the user Requested application connects to and interacts with a tier-3 database server using SQL DB server sends results to the tier-2 application Application wraps results in HTML, creating a webpage Webserver sends resulting webpage to tier-1 client. -If the web applications physically reside on the same computer as the webserve and interact with a database on a different computer |
|
|
Static Webpage
|
unchanging regardless of who is viewing or circumstance of viewing the page
|
|
|
Dynamic Webpage
|
change their content or presentation in one of two general ways:
-using client side scripting to change the webpage behavior within a specific web page, in response to mouse or keyboard actions or at specified timing events. In this case the dynamic behavior occurs within the webpage being displayed by the browser. –using server-side scripting to change the webpage source, adjusting content supplied to the browser. Server responses may be determined by such conditions as data in a posted HTML form, parameters in the URL, the type of browser being used, or the passage of time. |
|
|
Java and client side scripting
|
The web browser retrieves an html-page from the server, then the browser processes the code embedded in the page (typically written in JavaScript) and displays the retrieved page’s content to the user.
Problems: some browsers do not support the language or do not support all aspects- some users have scripting languages disabled in their browsers due to possible security threats. |
