To render a system executable, the term web application may also mean a software application in computer that is hosted in an environment which is browser controlled, or is coded in a language such as java script. Due to the convenience of using a web browser in the form of a customer which is called a thin client, sometimes and due to the ubiquity of web browsers, web applications and web based accounting software are very popular. The key reason for their popularity is the ability to maintain and update web applications without installing and distributing software on potentially thousands of client computers, as is inherent support for cross platform compatibility. Online auctions, online retail sales, webmail, wikis and many other functions are the common web applications.
Application specific add-ons such as access to the mouse and the keyboard, playing audio, drawing on screen, are all possible through Flash, DHTML, java script, java and other technologies. Very few limits on client functionality are place by the web interface. To combine all of these into a more familiar interface many services have worked to combine them to adopt the appearance of an operating system.
These technologies also support drag and drop and other more general purpose techniques. To add functionality developers of the web often use client side scripting, especially to create an interactive experience which does not require reloading of the page. A web development technique using a combination of technologies such as technologies developed to coordinate client scripting with server technologies such as Ajax, PHP, are examples of technology which offer an experience that is interactive.
Structure and business use:
Web based business accounting software and web applications are broken usually into ‘tiers’ which are logical chunks and a role is assigned to every tier. In a traditional application there is just one tier residing on the client machine. The web application lends itself to an n-tier by nature. The most common structure is the three tiered application, though many variations are also possible. Presentation, application and storage are the three tiers in its most common form. The first tier that is presentation is the web browser, and the center tier – application logic, is an engine which uses some dynamic web content technology such as Struts2, Ruby on Rails, Python, Perl, PHP, Java/JSP, ColdFusion, CGI, ASP.NET, or ASP. The third tier – storage, is database. Requests are sent by the web browser which services them by making updates and raising queries against the database and then generates a user interface.
A 3 segment may fall short for more complex applications. It is then that an n-tier may be required, where breaking the business logic is the greatest benefit. It resides on the application tier into a model that is finer grained. An integration tier can be added to separate the rest of the tiers from the data tier by providing an easy to use interface and enjoy access to the data. The underlying database can also be replaced without changing the other tiers.
To provide web access in business accounting software those which were distributed previously as local strategies are emerging strategies for application software companies today. Adopting an existing application to use different presentation technology or the development of an entirely different browser based interface depends on the type of application it may require. A monthly or yearly fee needs to be paid by the user to use a web based accounting software application without getting it installed on a local hard drive. ASP, or the application service provides is a company that capitalizes on the strategy and in the software industry, ASPs are becoming increasingly popular.
Writing applications online
By allowing the programmer to define a high level description of the program, there are frameworks of many web applications which facilitate rapid application development. Although there are not many viable platforms currently that fit this model, there is potential for the development of applications on internet operating systems. Number of errors in a program can be reduced by use of web based accounting software application frameworks, both by allowing one team to concentrate on just the framework and by making the code simpler.
Benefits and applications
As far as benefits are concerned little or no disk place is required by the client for browser applications typically, with new features upgrade automatically integrating easily into other server side procedures of the web such as searching and email in web based accounting software. In most cases like Linux, Mac, Windows they also provide cross platform compatibility because they operate within a web browser window. As far as browser applications are concerned in web based accounting software, they include Google Docs which is the most notable example, simple office software like presentation tools, online spreadsheets, word processors, and also include point of sale, video editing, computer aided design, and project management which are more advanced applications.
