The diploma project deals with the issue of Business Intelligence, it focuses on tools used for data analysis and presentation. The project is divided into two parts -- the theoretical and practical one. The theoretical one applies to the characterization of the principle, the description of the architecture components and presentation techniques. The aim of this project is to suggest new suitable analytical tools and graphic interface of BI system for small and medium-sized businesses. Using selected tools is illustrated on a specific example.

This degree project is a part of information and communication technology supported self-care system for the diabetes, mainly in diabetes data collection and visualization. The report is organized in four main sections: investigation and internet search, literature review, application design and implementation, system test and evaluation. Existed applications and research studies has been compared and, a responsive web application is developed aiming at providing relevant functionalities and services regarding diabetes self-management.

There is a lack in research on the perspectives of different managerial roles on data about software projects in software analytics tools, such as the perspectives of chief financial officers (CFOs), chief executive officers (CEOs) and compliance officers. Today, software analytics tools are mainly developed to address the needs of technical stakeholders such as developers, but research shows that there exist potentials of expanding this technical users’ scope of focus to also include higher level stakeholders, such as managers. The goal of this study is to explore what managers working in software development organizations consider to be useful data to have about software projects in software analytics tools, as well as examining how they want data about software projects to be presented to them in such tools. This study was done in four steps. First, a literature review was conducted. Second, a questionnaire was conducted with four CFOs, one CEO and one compliance officer working in six different Swedish software development organizations. Third, semi-structured interviews were conducted with three CFOs, one CEO and one compliance officer working in five different Swedish software development organizations. Fourth, a visual prototype simulating a software analytics tool was constructed based on the data gathered from the interviews. The result of this study shows that abstraction, limitation, and visualization of data about software projects, as well as presentation of useful data in software analytics tools that support the work tasks of managers, is helpful in addressing the perspectives and views of the target group.

The goal of this thesis is to optimize the existing energy consumption monitoring system and expand the presentation options for the measured data in a way that would be suitable for large volume of data and a long period of time. Optimization concerns especially data processing and data presentation.

In recent years, the use of video games has increased worldwide. A variety of industries such as business and education have taken a great interest in this phenomenon by applying game elements in a non-game context with the goal to increase users motivation. However, there are still areas where the use of Gamification is yet to be explored. One of these areas is Gamification applied to statistics, where there is a limited amount of research. Research suggests that statistics can be difficult for people to interpret, especially when there is a lack of interest involved. Therefore this study examined if Gamification could be used to to influence the user experience when presenting data in a dashboard. The user centered design method double diamond was used to create two prototypes, one with gamification and one without. These prototypes were compared through A/B testing, where the gamified prototype proved to be the winner, resulting in that gamification did have an positive impact of the user experience when presenting data in a dashboard. The resulting prototype proposes a way of how gamification can be applied when presenting data in a dashboard.

The purpose of this project work is to make research on vital sign’s data collection and datapresentation on handheld devices. With the development of smart phones and tablets, more andmore people prefer accomplishing their daily tasks on mobile devices. Additionally, theawareness of personal health care increases at the same time. This report consists of three mainparts: analysis, design and implementation and system evaluation. By studying literature andsearching related works on the internet, general design guidelines are documented. The result isthat a prototype is implemented with the functionalities of data collection and data presentation.The system test and evaluation are also completed.

A smart home is a building equipped with sensors collecting data about its environment. Data collected from smart home buildings can be used for research to improve home automation and develop smart cities. A scalable web-based system can be used to handle the large quantities of data generated from smart homes. Previous studies have been conducted on the requirements of a system collecting sensor data from smart homes, however, information about the presentation of data is still lacking. Because of this research needs to be done on what kind of system handles and presents sensor data well.The aim of this degree project is to identify the requirements of a web-based system handling and presenting sensor data. A scalable web-based system is developed based on the requirements identified from interviews and a literature study. The system shows that sensor data can be presented in a manner which facilitates research. Results show that a scalable web-based system can be used to display and download sensor data with associated information about the data. / Ett smart hem är en byggnad utrustad med sensorer som samlar data om sin miljö. Data insamlad från smarta hem kan leda till förbättringar i hemautomatisering och utvecklingen av smarta städer. Ett skalbart webbaserat system kan användas för att hantera stora mängder data som genereras utav smarta hem. Tidigare studier har genomförts för att framställa kraven utav ett system som samlar in data från smarta hem, dock saknas fortfarande information om hur denna data ska presenteras. På grund av detta behövs forskning om vilket typ av system som kan hantera och presentera data.Målet med detta examensarbete är att identifiera kraven för ett webbaserat system som hanterar och presenterar sensordata. Ett skalbart webbaserat system utvecklas baserat på krav identifierade genom intervjuer och en literaturstudie. Systemet visar att sensor data kan presenteras på ett sätt som underlättar forskning. Resultatet visar att ett skalbart webbaserat system kan användas för att visa och ladda ned sensordata med tillhörande information om datan.

This thesis deals with data extraction and data aggregation from heterogeneous web sources. The goal is to create a platform and a functional web application using appropriate technologies. The main focus of the thesis is on the application design and implementation. The application domain is accommodation or lease of apartments. For the data extraction, we use the portal API or a wrapper. Obtained data is stored in a document database. In this thesis, we managed to design and implement a system that allows to obtain rental ads from multiple web sources at the same time and to present them in a uniform way.
