Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems. TMap haven't been used as much as desired in the office in Borlnge. Because Microsoft is releasing a new version of their platform Visual Studio Team System (VSTS 2010) some colleges at Sogeti in the Netherlands are about to develop a template that can support the use of TMap in VSTS 2010. When we write this the template is still in development. The goal for Sogeti was to find out the differences between the test functionality in VSTS 2008 and 2010. By using the purpose with this essay, which was to analyze the test process in VSTS 2008 with TMap against the test process in VSTS 2010 together with the template we got much help to achieve the goal. The analysis was done with four different aspects: The TPI and TMMi models, problem and strength analyses and a few question formulations. The TPI and TMMi models where used to analyses and evaluate the test process. The analysis showed that there were differences between the both test processes. VSTS 2010 together with the template gave a better support to use TMap and perform test. In VSTS 2010 the test tool Camano is connected to TFS and the tool is also to make the execution and logging of tests easier. This leads to a test process that is easier to handle and has a better support for TMap.

In today's society it is becoming more and more important with direct marketing. Some of the direct marketing is done through e-mail, in which companies see an easy way to advertise himself. I did this thesis work at WebDoc Systems. They have a product that creates web documents directly in your browser, also called CMS. The CMS has a module for sending mass e-mail, but this module does not function properly and WebDoc Systems customers are dissatisfied with that part of the product. The problem with the module was that sometimes it didn't send the e-mail, and that it was not possible to obtain some form of follow-up information on the e-mail. The goal of this work was to develop a Web service that could easily send e-mail to many receivers, just as easily be able to view statistics on how mailing has gone. The first step was to do a literature review to get a good picture of available programming platforms, but also to be able create a good application infrastructure. The next step was to implement this design and improve it over time by using an iterative development methodology. The result was an application infrastructure that consists of three main parts and a plugin interface. The parts that were implemented were a Web service application, a Web application and a Windows service application. The three elements cooperate with each other and share a database, and plugins.

The client, Senselogic, had noticed an increased demand for an e-commerce system integrated into its product, SiteVision, something that did not previously exist. Senselogic wanted to integrate a third-party system to manage e-commerce. The problem was that there were very many e-commerce solutions to choose from. In order to select the best system it was necessary to evaluate the e-commerce systems and compare them to each other. To identify the elements that has to be included in an e-commerce system a study of literature was conducted. From the parts identified in the study of literature, a number of criteria were presented. Those criteria were then supplemented with additional criteria that Senselogic required of an e-commerce system before integrating it with SiteVision. Before the evaluation a number of test cases were created to test whether the ecommerce systems fulfilled to the criteria developed. These test cases were then used in the evaluation of the e-commerce systems while a test score was filled in. Then the evaluations of the different systems were compiled and compared in order to see which system best fulfilled the criteria. There was one system that scored higher than the others in the evaluation created. That was the system chosen to integrate with SiteVision.

A sequence of actions in the world have influenced the information science, one of these actions is the lateral movement in how companies use their IT-systems. IT-systems today, in comparison to before, are used by companies to improve their relationship with their customers. Every year a big amount of money is spent on developing and improving IT-systems. That is why it is important to develop and create IT-systems that are clear, and which encourage, enable and simplify a users action. There are criteria to use in actability and eTjnstetydlighet. I have in this thesis used acknowledged criteria for actability and eTjnstetydlighet to analyze two IT-systems that are equal to each other. This is to show how companies can develop and adjust their IT-system so that they will match todays point of view. I have also in this thesis chosen to evaluate the usage of criteria for eTjnstetydlighet and that is because no one has done that before. The result of this thesis gave Monster and Proffice measures for how to develop their IT-systems. The result of this thesis also gave indications of fuzziness when using criteria for eTjnstetydlighet, however, I was able to use the criteria the way they were supposed to be used to fulfill their purpose.

The purpose of this thesis is to present and describe which criteria, according to the systemfamily Configuration Management, should be met when developing a CM-tool to handlemigration data.ACT is a tool developed by Microsoft to gather information about, analyze, test and mitigateapplications in a network when migrating the IT-infrastructure of an organization to a newoperating system. The organization that is being studied wants to present the data about theanalyzed applications in such a way, that a customer can choose what to mitigate and migrate.The goal is therefore to develop a prototype (CM-tool) that will present this data.The study has shown that ACT lacks certain requirements stated by the organization when itcomes to presentation. But when it comes to the rest of the functions, ACT performs as expected.The investigation resulted in specifications and technical solution for the new CM-tool. CMcriteriafor migration data was put forth and parts of the prototype were also developed.

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts. The unclear concepts have remained in thedatabase and in the company organization and caused a general confusion of concepts. The splitdatabase architecture itself has evolved into a bottleneck and is the cause of many problemsduring the development of System Y.Company X investigates the possibility of integrating the historical database with the productiondatabase. The goal of our thesis is to conduct a consequence analysis of such integration andwhat the effects would be on System Y, and to create a new design for the integrated database.We will also examine and describe the practical effects of confusion of concepts for a databaseconceptual design.To achieve the goal of the thesis, five different method steps have been performed: a preliminarystudy of the organization, a change analysis, a consequence analysis and an investigation of theconceptual design of the database. These method steps have helped identify changes necessaryfor the organization, a new design proposal for an integrated database, the impact of theproposed design and a number of effects of confusion for the database.

Tack vare bttre och bttre frutsttningar fr utveckling av mobila applikationer, samt utbredning av internetbaserade tjnster, presenteras hr ett underlag infr val av mobil utvecklingsplattform. De underskta plattformarna r Android och Iphone p grund av deras vxande utbredning p smartphonemarknaden. Studien presenterar frutsttningar fr att utveckla webbtjnst-understdda applikationer fr intern distribuering. Ett visuellt tilltalande anvndargrnssnitt r ocks i fokus fr den typen av applikation studien riktar sig mot.Vi har kommit fram till att Android r lttare att lra sig om man kommer ifrn en Java- eller .Netmilj samt lttare att distribuera. Iphone har dremot bttre std fr att utveckla grafiskt tilltalande applikationer. Bda plattformarna har dock bristflligt std fr kommunikation via webbtjnster. Detta resultat uppnddes genom litteraturstudier, samt en fallstudie dr vi utvecklade applikationer med fokus p just webbtjnstkommunikation, intern distribuering samt ett tilltalande anvndargrnssnitt.

Nr man kombinerar ett objektorienterat programmeringssprk och en relationsdatabas uppstr en del problem fr utvecklare eftersom objektorienterade programmeringssprk och relationsdatabaser har olika fokus, objektorienterade programmeringssprk fokuserar p att avbilda verkliga objekt och relationsdatabaser fokuserar p data. De problem som uppstr kallas med ett samlingsnamn fr object-relational mismatch. Det finns flertalet ramverk fr att hantera dessa problem. Ett av dem r Entity Framework.Syftet med detta projekt var att utvrdera hur utvecklare tycker att Entity Framework fungerar fr att lsa problematiken runt object-relational mismatch, hur det r fr utvecklare att lra sig anvnda Entity Framework samt hur tillgngen p inlrningsmaterial r.Under vr studie har vi lrt oss anvnda Entity Framework samtidigt som vi gjort en studie av tillgngen p inlrningsmaterial. Vi har ocks byggt om en applikation s att den anvnder Entity Framework. Vi har jmfrt den ombyggda applikationen med den gamla applikationen fr att kunna se vilken skillnad som Entity Framework bidrog till.Vi kom fram till att Entity Framework hanterar object-relational mismatch p ett bra stt som bland annat gr att utvecklingsprocessen kortas ner d inte lika mycket kod behver skrivas. Utvecklare med tidigare kunskaper i .NET-programmering upplever att det r ltt att lra sig Entity Framework. Att det upplevs ltt att lra sig Entity Framework hnger frmodligen ihop med att tillgngen p inlrningsmaterial r god.

The report analyses if some common problems can be avoided by using modern technology. As a reference system Fartygsrapporteringssystemet is used. It is an n-tier web application built with modern technology at time, 2003-2004. The aim is to examine whether ASP.Net MVC, Windows Communication Foundation, Workflow Foundation and SQL Server 2005 Service Broker can be used to create an n-tier web application which also communicate with other systems and facilitate automated testing. The report describes the construction of a prototype in which the presentation layer uses ASP.Net MVC to separate presentation and business logic. Communication with the business layer is done through the Windows Communication Foundation. Hard coded processes are broken out and dealt with by Workflow Foundation. Asynchronous communication with other systems is done by using Microsoft SQL Server 2005 Service Broker. The results of the analysis is that these techniques can be used to create a n-tier web application, but that ASP.Net MVC, which at present only available in a preview release, is not sufficiently developed yet.
