1. Comparison among desktop application rich internet application and web application Particularly compare to the desktop application Rich internet application including AJAX shares a number of advantages No client installation required use can start use a program immediately Users can use the application from any computer with an internet connection and mostly platform independent Web based applications are generally less prone to viral infection than running an actual executable If there is a web alternative version available users are unlikely to install new software Compare to the traditional web application the rich internet technology eliminates the start stop start stop nature of interaction on the Web by introducing an intermediary layer between the user and the server Use Ajax as example instead of loading a webpage at the start of the session the browser loads an Ajax engine which is written in JavaScript This engine is responsible for both rendering the interface the user sees and communicating with the server on the user s behalf The Ajax engine allows the user s asynchronous interaction with the application to happen independent of communication
2. Today s CD ROM and online services are wonderful examples of software that prepares us for the possibilities of the future Imagine the best of both mediums combined and running on a high bandwidth high speed network high capacity shared storage that enables up to date rich multimedia content to be easily accessed by many people And by 2005 there will be applications that relate to all aspects of our lives Bill Gates 1994 At the time of this report it is 2006 and Bill Gate s prediction has recently been now realized as Applications Able to deliver Access to Anyone Authorized Anytime Anyplace on Any Device This is called the eight A s principle and these words are almost the most keyword advertised in the software industry nowadays SAA System Application Architecture from IBM is arguably the first attempt to comply these rules SAA was IBM s strategy for enterprise computing in the late 1980s and early 1990s now expanded by Open BluePrint By using this standard an enterprise could be assured of consistency and some amount of program portability among IBM s range of computer systems It is still a challenge now in the software development to develop the 8A s software distributed over n tiers as simply as possible The requirement from the 8A makes the software development to become increasingly complex because 8A s rule imply that the application is not confined in one machine but distributed into many tiers It is requi

Word work in different way and user need to be trained to use both systems No software installation more efficient more secure From the user s perspective this means the user can get their hands on the document much quicker User can start working with the document when sitting in front of any computer and do not have to worry about the working environment In addition this system consumes less resource of the client computer Microsoft Word typically uses memory over 30MB Gsurface 2004 A web browser typically uses memory below 20 MB or even less Besides almost all security issues for client side are also solved by this approach Because all operations are executed with browser with nothing installed no information except cookie and cache can be written to the client hard disk by JavaScript in principle Most of the security concerns like virus or spyware can not work even it are unknown For example a document contains a virus which will function when user open the document By using the system firstly the virus can be possibly killed by the antivirus firewall on the server even if the virus is unknown and it is not killed by the server it still cannot function because every document has to be rendered to HTML in this system User actually open the HTML file not the original file From the administrator s perspective Portability suit the current infrastructure To install the proposed system no change need to be made on the

35. e In the proposed system as can be seen from figure 2 3 the document will be encoded in HTML most of the time The only exception is when the user needs the document of the original format The process of working with a document is that when the user chooses to open a document the server returns the HTML version of the original document to browser User finishes editing the document and save it back to server The server does not apply the change to the original document Next time when the user edits this document the html version of last time is returned to browser without the conversion process The change only will be applied to original document when user chooses to download the original type of document In one word all jobs the system is performing are for the conversion between HTML and the Original Document Type To implement this idea the system will be built on the basis of C JavaScript and MySQL The reasons are stated below Before analyzing any detail of the technology the operating environment is investigated first 3 4 1 Operating Environment The system has a preferred environment Windows 2003 IIS 6 0 MySQL 4 0 Microsoft net Framework 1 1 In fact this system can run on Linux Solaris Mac OS X Windows and Unix with Mono framework Additionally the database system can possibly be replaced by Microsoft SQL Server or PostgreSQL The web server can be replaced with Apache These alternatives will be st

41. g In general the cross platform problem is partly solved or compromised on the premise of having a kind of working environment installed A broader problem is generated with this solution or this problem exists all through what if a specific word processor is not installed Not having support for a particular document type is frequently encountered It results in inaccessible document and no work can be done until word processor software installed providing it is possible to be installed The software can not be installed if no software is available or the system environment does not allow the installation By installing a number of software users can finally hand on the work but this is a waste of time and IT resource as stated following Waste of IT resource means the cost to manage these programs Management generally means customization upgrade configuration and security As every computer in an organization has to be installed a copy of the word processor to maintain these copies are usually a complex task In order to save the cost and effort the document processor needs to be centralized This means no software installed on the client side all document processing are executed on the server side How the centralization can be achieved A client that needs less maintenance is required and it must be widely available The suitable candidate is an editor in web browser 2 3 An alternative WYSIWYG Html Editor HTML and JavaScri
