Smartphones are used by incredibly many people, and in 2011 there where a total of 491.4million units soled worldwide. Smartphones are known as advanced phones, or personal digital assistants (PDAs). This makes a relevant technique for performing dietary studies when the test patients are on the move. This thesis shows how to create a back end environment for an Android application with existing techniques linked together, using MSSQL database, Visual Studio Web Service, web pages and C# classes and ASP.NET security.The back end development is used in a dietary study on Gothenburg University, but could be applied on many similar back end projects using databases and server development.Techniques used in this thesis are: REST (Representational State Transfer) -clientimplementation and development inside the Android application, using HTTP methods toset and get information from the server and database, and JSON-format to read and transfer information in an easy and understandable way, both from the Android application and from the database. FileMaker is also used in this project as a third part programme to visualise the information in the database.

Vi fick av netweb.se uppdraget att tillverka ett webbaserat tidbokningssystem. Detta tidbokningssystem skulle vara möjligt att applicera på många olika typer av verksamheter. Kunden framlade ett önskemål om att systemet skulle byggas i ASP.net.Tillsammans med detta system har vi även fördjupat oss i användbarhet och utnyttjat denna studie till att göra ett användbarhetstest. Resultaten av testet har utvärderats och applicerats på systemet.Projektet ledde till ett färdigt tidbokningssystem. Resultatet av användbarhetstestet visade på skillnader mellan yrkesgrupper, där människor inom databranschen hade störst svårigheter att ta till sig systemet. Anledningar till detta kan vara att utvecklare och datatekniker fokuserar på fel saker när de bedömer ett system, samt inte tänker som en användare. Även skillnader mellan kön och åldersgrupper visade sig i resultatet av användbarhetstestet.

Syftet med projektet var att tillverka en webbaserad kartvisningstjänst för att visualisera geografiska och infrastrukturella förändringar över tiden. Detta genom att historiska och dagsaktuella kartor överlappas och presenteras som en bild.Applikationen utvecklades i ASP.NET med programspråket Visual Basic. Som databashanterare användes Microsoft SQL-server 2000. För bearbetning av kartmaterialet användes Arcview 8. Som utvecklingsmetod användes David Siegels modell för att konstruera webbplatser. Rapporten tar upp Ben Schniedermans principer för att skapa användarvänliga webbapplikationer.Examensarbetet genomfördes våren 2004 vid Högskolan Dalarna, campus Framtidsdalen, Borlänge.

<p>Nowadays there are different forms and technologies for implementing web applications without much concern for their architectural model. Without a good and stable architecture those applications may fail during their operations. Thus, this thesis project is focused on exploring different architectural models for creation of web solutions. Moreover, this thesis project is also part of the collaboration between Linnaeus University and Ljungby municipality with the aim to create a system that grow up local economies by showing the local producers’ locations, providing customers with different information about the products etc. The result of the thesis shows that an application can be developed in various architectural models. The choice of one architectural model over another depends on the project needs. I found that by using ASP.NET MVC framework there is more separation of concerns, easy maintenance of the code, and unit testing for an application. Search engine of find local food system can be used to search for different local producer’s location and their services.</p><p> </p>

This thesis deals with usage of MVC (Model View Controller) technology in web development on ASP.NET platform from Microsoft. Mainly it deals with latest version of framework ASP.NET MVC 3. First part describes MVC architecture and the second describes usage of MVC in certain parts of web application an comparing with PHP.
