My independent work has been to modernize a user interface in a 10-year-old MVC Framework application used by Skärblacka mills within the BillerudKorsnäs Group. The concept of modernization also means increasing its quality; to replace older knowledge and technology with new and modern technology such as be able to click on the text of a checkbox that is considered to be more relevant for its time. The framework chosen for the implementation was ASP.NET Core MVC, which is an open source for the most common platforms. The implementation of the porting meant that server code that is well-functioning has been maintained to a large extent. JavaScript is also pretty much the same except in a few places. To get a good and durable structure, the application is layered in the form of 3 layers with Controller, BusinessLayer and Repository. The database with SQL Server is basically the same except that Identity has been introduced. To be able to communicate with the database, ORM EF Core has been chosen, which is a slim version of EF. A lot of what is in the old MVC framework has been redesigned because it is not supported in Core MVC. The application consists of an assembly with a logical development tree that consists of the files included in the application.Ajax has been used to get soft desktop-like updates.The application, which is complex with a lot of complicated things, made time run away. / Mitt självständiga arbete har varit att modernisera ett användargränssnittet i en 10 år gammal MVC Framework applikation som används av Skärblacka bruk inom BillerudKorsnäs koncernen. I begreppet modernisera ligger också innebörden att öka dess kvalité; att byta ut äldre kunskaper och teknik mot ny och modern teknik som t.ex. kunna klicka på texten till en checkbox som anses vara av mer relevans för sin tid. Det ramverk som valdes för implementationen var ASP.NET Core MVC som är ett open sourse för de vanligaste plattformarna. Genomförandet av porteringen innebar att serverkod som är väl fungerande har bibehållits i stora delar. Även JavaScript är i stort sett densamma förutom på några få ställen. För att få en bra och hållbar struktur är applikationen skiktad i form av 3 lager med Controller, BusinessLayer och Repository. Databasen med SQL Server är i stort sett densamma förutom att Identity har införs. För att kunna kommunicera med databasen har man valt ORM EF Core som är en slimmad version av EF. En hel del av det som finns i den gamla MVC framework är omgjort eftersom det stöds in i Core MVC. Applikationen består av en assembly med ett logiskt utvecklingsträd som utgörs av de filer som ingår i applikationen. Ajax har används för att få mjuka desktop liknade uppdateringar. Applikationen som är komplex med en hel del komplicerade saker gjorde att tiden rann iväg.

This thesis deals with the Featured Driven Development (FDD) agile methodics. To support this methodics, an information system has been created, providing all team-members with instruments to follow the methodics. This multi-user system is implemented as a web-based application, enabling creation of a feature list,  plan a project, support the cooperation among the feature team members and watch the project progress in an illustrative way. To improve the visualization possibilities, a wide range of reports aimed at the company management and the client is provided.

Modern web applications are growing in complexity and becoming more widely used. Using frameworks to build APIs is a popular way for both hobby developers and businesses to speed up development time and save costs. With this dependence on frameworks to be the foundation for potentially large applications comes the need to understand their performance qualities and which areas they are best suited for. This study compares the performance of the two similarly popular frameworks ASP.NET Core and Express.js, when used together with a MySQL Database to build Web APIs. This was done by building two different API implementations in each framework, one employing a RESTful approach and the other using the new querying language GraphQL. Experiments were run where the peak CPU usage, peak memory usage and response times were measured.The results of the experiments were that in a RESTful API, ASP.NET Core is faster at serving requests during lower loads whereas Express.js outperforms ASP.NET Core when faced with a higher amount of concurrent requests that fetch a lot of data. In a GraphQL API Express.js was able to perform similarly or better in all cases in terms of response times and resource usage compared to ASP.NET Core.

<p>This paper describes the evolutionary development of an information system for a small company. The company performs overhaul of forklifts and cleaning machines. The company has already an information system that handles the reports from these overhauls but it needs a supplementary tool that assist the chief planner to plan forthcoming overhauls.</p><p>It should be able to display coming overhauls in a timetable and eventually print them, either to a PDF file or to a document. The timetables this function produces will help the chief planner and the assemblers to get a good overview of their day-to-day work.</p><p>The tool needs to be intelligent in that way that it takes into consideration were in the country different assignments will be performed. So that time consuming travels over great distances can be avoided. This coordination will lead to higher profitability for the company and more satisfied customers.</p><p>The paper contains theoretic background about what models and methods that are used in the development of an information system. This theoretic background is then used when developing a system in practise and the result of this is then showed. In the end the results are compared to the demands, goals and requirements stated in the beginning of the paper, to see if they are fulfilled.</p><p>This is a degree thesis at the S c ho o l o f E n gineering, Jö nkö pin g U niversity.
