Rapid Web-Based Desktop And Mobile Application Development



Velocity in the demand for new applications and functionality rises as businesses grow. As a developer, you are expected to rapidly respond to these needs. Over the years, desktop database and spreadsheet tools have enormously contributed to data management due to the ease and user friendliness these applications extend to their audience. Besides benefits, these applications have scalability and functionality limitations that not only results in dozens of different applications and data sources but also adds extra overhead in their maintenance. Due to these issues, organizations are unable to continue their standard practices, leaving mission-critical data at risk. These fragmented systems may also cause loss of business opportunity. Finally, a significant amount of time and resource is required to put these data blocks together to get the desired information. In addition to above, the following points provide some more drawbacks of desktop applications:

  • Installation of client software, such as Excel or run-time binaries, on every machine.
  • Lack of data sharing with other applications.
  • Simultaneous data access inability in spreadsheets.
  • May not be the part of regular data backup.
  • Critical and confidential data can easily be moved via email or pocket storage devices.

With the above deficiencies, it is clear that you need a tool that has the capability to cope with these shortfalls and extends the following features:

  • Central management of data and applications.
  • No installation of software is required on client machines; the only requirement is a supported browser.
  • Shared development and application access.
  • Being central, data and applications become a part of regular backup procedure.
  • Data and application access control; empowered by audit trail.

If you want to develop and deploy fast and secure professional applications then you must go for a rapid application development (RAD) tool. A RAD tool only requires a web browser and a little programming experience. Besides ease of use and flexibility, RAD tool provides the qualities of an enterprise database, scalability, security, integrity, availability and above all the web development experience.

These tools provide a declarative programming environment, which means that no code is generated or compiled during development. You just interact through wizards and property sheets to build SQL-based reporting applications on existing database schemas. Reports and charts are defined with simple SQL queries, so some knowledge of SQL is very helpful. Besides, if procedural logic is needed, you can also write your own custom code. These declarative tools have a vast collection of pre-defined wizards, HTML objects, database handling utilities, page rendering and submission processes, navigation and branching options, and more. You can use all these options to build your database-centric web applications comprising web pages carrying forms, reports, charts, etc., with their layouts and business logic. The back-end engine translates it all into an HTML code for the client side, and SQL and custom code for the server side. If you do not get a solution from predefined options, you are allowed to create your own code for the server side, and HTML, CSS, and JavaScript code, for the client side.

Web applications are quickly taking over conventional desktop counterparts. A web application is an application that is accessed by users over a network such as the Internet or an intranet. It is an application software that is coded in a browser-supported programming language (such as JavaScript, combined with a browser-rendered markup language like HTML) and dependent on a common web browser to render the application. The popularity of web applications is due to the ubiquity of web browsers, which is the only requirement to access such applications. Another major reason behind the popularity of web applications is the ability to update and maintain these applications without distributing and installing software on potentially thousands of client devices.
