Abstract

Much research has been carried out on the importance of design patterns as a tool that saves time in the design of a software program and establishes helpful results in different platforms. However, the methods for pattern representation, organization , saving and restoring have not been stated clearly. This study attempts to find an easy way to turn data into an XML (extensible markup language) file that shows the component pattern as a text, and in order to help the designer to organize and save such patterns. We begin by applying a design pattern that has been described and documented by a catalog, published on a web page and stored in xml format. The store operation consists of saving the page, taking the content and using it in an application. Most the time these patterns are reduced, because no clear methods for saving and returning the data when it is needed are available. A tool is required to perform this task. The tool will be applied by using an xml–based parser that compiles an xml file and transforms it into a formula understandable by all designers. The proposed tool will use the HTML (Hypertext Markup language ) technology to display the xml-file as an acceptable text, desired by the designer, and suitable language such as vb.net and asp.net will be selected to implement the tool. The aim of the present work is to provide a work mechanism for designers. This mechanism will allow information and experience to be exchanged among designers in different programming environments, and also reduce time and effort in the design of reliable solutions to problems.
