Analysis of already created portals, which appeal to national research and development works presentation, are made. Lacks and advantages of existing portals are overlooked and considered for prototype development. National research and development portal functions are described and solution is presented. Product was built as a specific content management system (CMS). The range of CMS products offers more than 10 different functions, but not all of them are necessity. The most useful functions are chosen and produced for this product. The need of architecture sketch occurs, when creating CMS or running a CMS-like website. Separation from structure, contents and representation issue is described and solutions are provided.

This thesis deals with the creation of an application developed for a real company using Web Dynpro ABAP technology. The application allows devices running on Windows Mobile platform access to SAP warehouse management.

Patterns are a source of knowledge when architecting software systems. They provide abstract and time-tested solutions that show how a system should be structured to achieve needed qualities. However, when developing software there is a chance that small mistakes are introduced in the source code. Over time, these mistakes can accumulate and break the structure of the pattern and its qualities are lost. There are methods that can help find such errors, but none of these provide a pattern abstraction. In this work, we describe a method that raises the level of abstraction from checking individual dependencies to checking key dependencies in the pattern. We implement our method, apply it to check the Model-View-Controller pattern. We show that the method can find architectural problems in real source code and examine how removal of detected erosions affects the source code. We conducted an experiment in a software project setting to determine if using the method affects the number of architectural problems. Some project teams were randomly assigned to use a software service that automated our method. It checked how well their implementation conformed to Model-View-Controller every time they updated the source code. The experiment showed that developers that used the tool had significantly fewer detected architectural problems during the course of the project. Our method makes conformance checking easier to use. This might help increase the adoption of conformance checking in industry.

This thesis presents the theory behind prototyping and user interviews as parts of requirements analysis. It further discusses how these were used in the development of a budget planning application. The implemented Web-based solution uses a new component-based design rooted in a Model-View-Controller architecture. The application is used today with complete success at the Department of Computer and Information Science at Linköping University.

På WM-data har man utvecklat ett ramverk som heter Java Development Platform med avsikt att modellera större delar av ett system och därmed minska mängden kod som måste skrivas för hand. Ramverket baseras helt på existerande öppna lösningar och används vid utveckling av webbaserade system och skapar en skiktat lösning med en webbapplikation som presentationslager. Problemet är att webbapplikationen har kommit att bli väldigt svår att modellera i enhet med resten av systemet framför allt på grund av den hårda kopplingen till Struts-ramverket. Samtidigt har man börjat få upp ögonen för AJAX och vad det skulle kunna tillföra ramverket. Examensarbetet fokuserar på att utreda de problem som existerar i ramverket samt undersöka integrationen av AJAX ur en synvinkel som gynnar dagens lösning. Detta görs genom litteraturstudier, laborationer och genom att undersöka existerande ramverk och plattformar som löser liknande problem. Fokus ligger även på hur AJAX kan användas för att lösa problemen i modelleringen. Resultatet av arbetet mynnar ut i en analys som behandlar de aspekter som krävs för att AJAX ska kunna bli en del av JDP-ramverket. Analysen innefattar också synen på hur AJAX skulle kunna användas för att underlätta modelleringen av webbapplikationen utan att införa något nytt modelleringsverktyg, det vill säga att UML fortfarande kan användas. / At the WM-data company a framework called Java Development Platform has been developed with the intention of developing a system by first modelling and generating a major part of it instead of handwriting everything from scratch. The framework is based solely on existing open source solutions and is used for developing layered web based systems with the web application as the presentation layer. The problem is that the web application has become very difficult to model in the same way as the rest of the system especially due to the tight coupling between the model and the Struts framework. At the same time, AJAX has been getting more and more attention for its application areas as well as how it can be used to solve the problems with modelling the web application. The thesis intends to focus on researching the existing problems in the framework as well as investigate the integration of AJAX from a standpoint that the framework can benifit from. This is done through literature studies, laborations and by looking at existing frameworks and platforms that aim to solve problems like the ones in JDP. The focus also lies on how AJAX can be used to solve the problems with modelling the web application. As a result, the thesis ends in an analysis which considers the aspects needed for implementing AJAX into the JDP framework. The analysis also discusses how AJAX can be used to facilitate the modelling of the web application without having to model it in another way other than through UML diagrams.

The PhonePages of Sweden is a company that develops software for mobile units, especially cell phones. This thesis treats the development of, and contingencies for, a mobile phone directory, using the limited resources found in a mobile unit. The project was implemented and executed at The PhonePages with the intention of creating a product to sell to a third party. By studying different solutions, their benefits and drawbacks, an abstract picture of the product was constructed. Problems covered include compatibility problems caused by todays platform diversity as well as problems with saving, organizing and presenting data. The main goal was to create a phone directory which does not make external information retrievals. The service should contain both company and personal information, with name and phonenumber. Complete address information should also be available. The application should also manage different priorities and logotypes for the company information. The application, that emerged as a result of our work at The PhonePages, works independently, without making connections to the Internet and is completely implemented in J2ME, all according to the requirement specification. In other words, the analysis of the different solutions led to a working application.

This thesis represents the Model-View-Controller pattern. It is focused especially at the description of the particular architecture layers principle and its functionality. It deals with the reasons of the three-layer architecture invention and it also deals with the advantages and the disadvantages provided by this pattern. The most frequent implementation of the MVC – the access to the data stored in the database through the web user interface is also described in this chapter. The next part of the thesis is concentrated on .NET Framework platform created from very voluminous, language-neutral library that is basically huge collection of the source codes providing the solution for common programmer’s problems and from the interface used for running up the applications created in .NET environment. The goal of the chapter concering with .NET Framework is to describe its architecture. The thesis also describes the platform invention, various versions of the .NET, the data access technology ADO.NET and the ASP.NET member ObjectDataSource. The chapter describing languages supported by the .NET Framework is focused on the C# language and its versions. The application “Multilayer applications in .NET environment” is the practical implementation of the mentioned technologies and it is described in the last chapter. The application’s architecture with the concentration on the particular Model-View-Controller layers implementation in the form of Microsoft Visual Studio 2005 projects is also described in the thesis. Special attention is paid to each operation over the data stored in the database tables that the application enables the user to execute, as for example data inserting, updating, selecting or deleting. The common business object’s child generation process is also described deep into the details.

A good health condition is important to maintain. It is a root cause to many other positive aspects in life. Productivity in a working industry can be improved if employees have a good health condition. Because of this, some companies are interested in keeping their employees as healthy as possible. The IT-consulting company CGI uses an in-house developed application, called CGIMoving, to offer exercise campaigns for its employees to encourage a healthy lifestyle. CGIMoving is a web system for logging physical exercise activities, where employees can voluntarily participate and log their workout activity and earn rewards. The CGI members who are responsible for the project have made a backlog with features that they wish to be implemented. The goal of the project was to improve CGIMoving by implementing a set of chosen backlog features. Product improvement was done according to an agile Scrum methodology. Tools and techniques used were the ASP.NET web-development framework and the Model-View-Controller design pattern with Visual Studio as the development environment. This report documents the development of six improvements to the CGIMoving system. These improvements are documented in the implemented order: (1) create predefined activities for a campaign, implementation of reminders for (2) inactivity and (3) unclaimed rewards, (4) edit user registered activities, (5) edit information about users and (6) create events. The improvements resulted in an upgraded version of the product. / <p>Digitalt presentation via Zoom</p>

This master thesis deals with an architecture Model-View-Controller. It explains the principle, model, usage and benefits of an architecture. Futhure more, it presents the best known web frameworks on Java platform which derive benefit from this architecture. There are frameworks like Apache Struts, Tapestry and Spring. In my thesis, the principles of framworks and the work with them are described. Concerning another part of my thesis, there are simple applications which use this frameworks. The work gives instructions to make these applications. It describes and compares the latest versions of these tools. It deals more with framework Spring, describes its elementary principles and modules with enhanced sight to Web MVC of Spring.
