Using XML as an Intercommunication medium in Web-Based Information SystemsHelgason, Magnus Thor January 2001 (has links)
<p>The Web has been defined as the interface between Web servers and Web clients. Traditionally, HTML has been used as an intercommunication medium for the Web. Web-Based Information Systems (WBISs) is the most general class of Web sites being fully distributed, platform-independent and having a hypertextual user interface. XML is emerging as a new standard for data exchange and data representation on the Internet. The W3C Consortium is responsible for the development of standards for the Web. In this dissertation we have showed how XSL and XPath could be used to meet the query requirements of SWISS-PROT, which is a WBIS. We have showed that XSL offers some level of extensibility as a query language for SWISS-PROT, but if queries were to be extended to a high level of complexity XQuery would be more appropriate to use since using XSL for this purpose includes hand-coding of for-loops and if-statements. Another problem is related to maintenance. Updating the structure of the XML source would include updating hand-coded for-loops and if-statements. There is still no recommendation available for XQuery at the W3C Consortium. Considering other factors of information management, we have showed that XSL and XPath would play a significant role in displaying and formatting information in SWISS-PROT. This would though require that Web browsers in SWISS-PROT have standardised support for XML.</p>

Assuring Quality in Web-Based Information Systems : A quality-driven design modelTheodorsson, Mike, Rydiander, Ida January 2007 (has links)
<p>Quality has always been an elusive concept in information system design, even more so when dealing with the online-sphere. The purpose of this thesis is to investigate and dissect the concept of quality and present a practical way to apply it to the design process. To do this, a quality-driven design model has been developed, focused around four crucial aspects of overall quality: accessibility, usability, navigation and interactivity. By utilizing simple and practical techniques and measuring their success in achieving quality, this study attempts to prove that quality can be harnessed as a hands-on resource, guaranteed in any design project involving a Web-Based Information System, merely by applying this model.</p> / <p>Kvalitet har alltid varit ett begrepp svårt att fånga och tillämpa, speciellt när området Internet kommer in i bilden. Den här C-uppsatsen har således som syfte att undersöka och bryta ned kvalitetskonceptet samt presentera ett praktiskt tillvägagångsätt som kan utnyttjas under design processen. För att göra detta så har vi utvecklat en kvalitetsdriven designmodell, fokuserad runt fyra kvalitetsaspekter: tillgänglighet, användbarhet, navigation och interaktion. Genom att utnyttja praktiska och enkla tekniker och genom att mäta deras effektivitet i att utveckla kvalitet, så försöker den här studien att bevisa att kvalitet kan användas som en praktisk resurs. Kvalitet kan garanteras i alla designprojekt som involverar ett web-baserat informationssystem, genom användning av denna modell.</p>
