Development and system architecture The application I am trying to develop is an online application program. The program finds the host from a dedicated hosting server where it incorporates the databases and website and any individual can gain access to the website through a web browser. The most suitable programming language for developing this online app is the PHP language, which is an open source platform. The reason for using the PHP platform as the most suitable development tool for this project was based on different factors of which some are explained below. a) Performance-This is small app and intended the best option is an open source platform, a position which PHP can easily fill. b) Maintainability - It is a more user friendly and robust in nature. c) Cost-The cost involved is minimal, as the open source PHP and MySql can be easily downloaded from the web at no cost, not forgetting the free licensing. This option looks more enticing in comparison to ASP.NET or.NET framework from Microsoft which is more expensive. d) Compatibility-The PHP platform is an open source platform, thus making the app compatible to many sites and transaction. Therefore, the PHP is the most suitable server side language to adopt for this project. class StockHelper { // private values that are stored within this class private $code = ''; private $price = ''; private $volume = ''; private $change = ''; private $content = ""; // This method retrieves the HTML of a data source customised by the $code value // which would be a valid stock code.
