Today's healthcare computer systems rely upon a disparate collection of legacy services, all developed separately and independently for patient records, radiological images, scheduling, billing, and administration. The Web is based on a client-server model. It consists of a set of servers, known as Web servers, which receive one request at a time and respond to that request without preserving state information, and a set of clients, known as Web browsers, which make requests based on user input and present results. Several efforts have been undertaken to address security in the Web, although the primary focus has been at the application level. These efforts have addressed the issue of protecting the privacy, accuracy and authenticity of transactions conducted over the Internet. In this work we will discuss cutting edge security tools in Microsoft’s newest .NET framework version, how to use and witch to choose, how to integrate them in medical environment, will see how they meet today’s medical web services requirements and will propose some methods to make securing of web services easier and more reliable.

The theoretical part of the thesis deals with the Microsoft .NET Framework, development environment Visual Studio and C # programming language issues. The practical part of the thesis deals with the Software management issues in company and the subsequent implementation of a customized solution. In the first part the practical part focuses on analysis of the current process which is based on defined requirements of the proposal for optimizing the processes of the central management software. This process is designed using a multi-layer architecture and includes a user interface on the ASP.NET platform, a central database SQLite, the internal logic of the system implemented using Windows system service and proposing a centralized repository of the source data, application scripts and installation records. In the second part focuses on the design and implementation of individual parts of the system. In the last chapter the verification methodology of the created prototype is introduced. The final evaluation summarizes the thesis, selected solutions and the results of the tests performed in a real environment. The created system allows the simple way to centrally manage applications in a company.

The thesis deals with module extension in currently developing project called Time Project 5. Specifically, the Phases, Notification and External Interface module. The thesis is divided into four major chapters. The first chapter introduces theoretical background consisting of backend and frontend technology description. The second chapter serves as determination of customer's expectations in form of functional and nonfunctional requirements gathering. The major focus of the third chapter is on application architecture design of both server and client side together with subcomponents design. Additionally, this chapter is complemented by the data model and Time Project 5 application design. The last, and at the same time, major chapter reveals the actual implementation of mentioned subcomponents including further necessary support features.

The theoretical part of this thesis is focused on possibilities of the WebML modeling language and the WebRatio CASE tool. The practical part of this thesis deals with design and analysis of web application supporting the processes associated with the telecommunications and processing of data obtained by PBX. For the process will be used WebML based on acquired knowledge.

Detta projekt har, för företaget Gisys räkning, gått ut på att från grunden skapa en applikation som förenklar processen när en nyanställning sker i företaget. Med detta menas ett gränssnitt där man kan lägga upp nya personer, utskick av formulär där den kommande medarbetaren får fylla i uppgifter och önskemål, utskick av övriga mail och checklistor där ansvarig på Gisys kan bocka av vad som är gjort och inte. Resultatet av denna applikation ses nu som en start på något större, efter många avstämningsmöten har kallar vi nu detta ett mindre intranät där nyanställningsprocessen snarare är en modul utav den större applikationen. Efter ett lyckat arbete och god respons från Gisys så finns planer alltså på att vidareutveckla applikationen med fler moduler.

This Master thesis enhances an existing library search system with a new dynamic web interface and introduces the ability to perform remote searches by using Web Services. The remote search functionality also includes the ability to compress SOAP-messages, this functionality is optional. The system is implemented using the Microsoft.NET Framework with Visual Studio C#. A library needs to store information about articles and we have chosen to use a Sybase Adaptive Server Anywhere database. The practical part of this thesis describes the architecture of our implementation and the design process. The theoretical part is a comparative study between dynamically created web pages and static pages, SOAP-compression versus no compression, SOAP-optimization versus no optimisation and the use of Web Services locally versus local classes.

The company System Andersson is developing systems for controlling materials and production in industries. They want to add a new service, where parts of those systems are accessible through cell phones. In this paper we are investigating which technology are best suited for this kind of application. And then we describe how we are developing a prototype fort this application, based upon that technology. After investigating technologies such as Java ME, Microsoft Silverlight, and web applications we settled upon building the system as a web application, customized for a mobile environment. To build a web page which is readable by many different cell phones we use the markup-languages which are developed for cell phones. We put much effort in reading about the standards and recommendations for the mobile web, produced by the organizations W3C and OMA. It's also very important that one consider the limitations of cell phones, such as the small screens, their limited performance and their limited means of input and navigation. Finally we are very thorough in our testing on several cell phones created by different manufacturers and with different operating systems and web browsers. On the server we are running ASP.NET, with a database using Microsoft SQL Server, since this was a request from the company. The development is made in C#. We reach a fully operational application with the functions that the company has requested. We got functions for handling orders, changing jobs, supply management, listing employees, and more. We also got a class for generating and rendering of lists and tables for easy and customizable lists for small screens. The application has support for several users with a secure login function. We have also created a system running as a service in Microsoft Windows, which is regularly sending messages, in the form of e-mails to the users of the mobile application. The messages contain user defined reminders, e.g. that the factory is running low on a certain material. The message system is well integrated with the rest of the system, in which one can list the active reminders, edit them or create new ones. Overall this has been an interesting and successful project.

This is a degree work, connected to the education Media and Communication engineering at the University of Linköping, and is made for TEFK a furnishing company in Sjövik. The purpose of this degree project is to create a visual identity and to develop a databasedriven website. The goal was to clarify the visual identity and to build an appealing website that could be administrated by the company. They had a need to present their products and to let their customers be able to order directly through their website. The website also had to serve as a part of the marketing by informing the visitors about the company. The result became a website developed in ASP.NET that presents the company and its products and lets the costumers place orders. Further they now have an interface for easy management of the website and its content. The company has guidelines on how to produce graphical content. On the basis of these guidelines we produced a new businesscard and document templates for common communication. In the end both we and the company are very satisfied with the result with this degree project. This thesis describes the work that has been done.
