Abstract This bachelor thesis will present the XAP tool integration project. Apart from presenting the survey of integration techniques that includes integration models and case tool models, we have conducted a comparison of these models. Then we reason about their applicability in the XAP setting. We apply this survey into the XAP tool integration project – integrate three tools in one IDE on data level. In this IDE, the user can create a new project and use these three tools freely in the new created project. The database among them is shared.

In this report a method is applied that was originally developed for the creation of evaluation frameworks for CASE-tools. Here the method is taken out of its original context and applied for the creation of an evaluation framework for database design transformation in CASE-tools. The focus of this report is on the process of creating the framework and not on the resulting framework. The creation of the framework is divided into two main processes. During phase1 a framework is developed from existing literature. This framework is then refined in phase 2 when the framework is tested in an in-depth exploratory study of support for design transformation in two commercial CASE-tools.

The topic of this thesis is the introduction and use of the ArchiMate enterprise architecture modeling language. The main goal of the thesis is to describe the basic principles and elements of the ArchiMate language. Other objectives are creating of an overview of CASE tools which support ArchiMate and demonstration of the capabilities of the language in a practical example which deals with the modeling of enterprise architecture of a selected organization. The thesis is divided into four parts. Introductory part uses available sources to define basic concepts of the enterprise architecture. Second part introduces basic principles and elements of the ArchiMate language based on an official documentation. This part also includes a market research of CASE tools which support the ArchiMate language. The third part of the thesis describes an example of the ArchiMate language use for the modeling of enterprise architecture of a selected organization. The final part discusses pros and cons of ArchiMate and summarizes results of the entire thesis. The main contribution of this thesis is that it provides a manual for potential users of the ArchiMate modeling notation. Other benefits include creation of a list of available CASE tools supporting the language and a showcase of possible practical uses of the ArchiMate language.

The global climate and energy crisis has amplified the need for renewable energy sources, withsolar photovoltaic (PV) systems expected to play a significant role in the future energy mix. In this context, distributed energy systems (DES) are identified as part of the solution to address climate and energy challenges.With the increasing demand for photovoltaic energy sources, there is a growing requirement forefficient Business Case Tools (BCT) to analyze investments in distributed solar PV installations.A two-part model, consisting of a solar model and spot price data, was developed based onparameters such as solar radiation, location, angle, orientation, system losses, installedcapacity, and historical spot price data. The model was integrated with Power BI for investment calculations and visualization of results. The developed model provides approximations for solar PV system electricity production, which were validated against selected installations in allelectricity areas of Sweden. The validation revealed an average relative absolute error of 14.72 percent for the model. The conclusion drawn is that BCT can be utilized to analyze and visualize solar PV investments at specific locations in Sweden. The results indicate that Power BI, as a BCT, has limitations indynamic data collection but performs well in executing calculation of investments and visualizingthe results. Well-developed BCT can facilitate decision-making through real-time calculations and contribute to smoother implementation of distributed systems by providing detailed insightsinto their financial characteristics. Further research is needed to develop a model specificallytailored for distributed installations with storage capabilities. / Världen befinner sig i en global klimat- och energikris vilket ökat behovet av och efterfrågan på förnybara energikällor. Solceller förväntas utgöra en betydande del av den framtida energimixen. I kombination med detta identifieras distribuerade energisystem (DES) som endel av lösningen på klimat- och energifrågan. I takt med den ökade efterfrågan på fotovoltaiska energikällor ställs större krav på effektiva Business Case Tools (BCT) för att analysera investeringar i distribuerade solcellsanläggningar. En modell bestående av två delar, en solmodell och spotprisdata,utvecklades utifrån parametrarna solstrålning, plats, vinkel, riktning, systemförluster, installerad effekt samt historiska spotprisdata. Modellen sammankopplas med Power BI föratt utföra investeringskalkyler och visualisera resultatet. Den utvecklade modellen gerapproximationer för solcellsanläggningars elproduktion, vilket validerades mot utvaldaanläggningar i Sveriges samtliga elområden. Enligt valideringen uppgår modellens genomsnittliga relativa absoluta fel till 14,72 procent. Slutsatsen dras att BCT kan användas för att analysera och visualisera solcellsinvesteringar på specifika platser i Sverige. Resultatet visar att Power BI som BCT har brister när detkommer till dynamisk datainsamling, men genomför och visualiserar investerings kalkyler med enkelhet. Välutvecklade BCT kan användas för att underlätta beslutsfattande genomrealtidsberäkningar och kan bidra till en smidigare implementering av distribuerade systemgenom att belysa deras finansiella karaktär på ett detaljerat sätt. Fortsatt forskning krävs föratt ta fram en modell anpassad för distribuerade anläggningar med lagringsmöjligheter.

Si les nouvelles technologies en matière de SGBD envisagent le problème de l'évolution du schéma d'une base de données, les systèmes d'information actuels posent des problèmes particulièrement ardus lors des phases d'évolution. Ce travail étudie ces problèmes dans un contexte pratique tel qu'il est vécu actuellement par les développeurs. Il propose une typologie complète des modifications possibles ainsi qu’une analyse du phénomène de l'évolution et de son impact sur les structures de données, les données et les programmes d'application au travers de stratégies typiques. Le document décrit ensuite l'environnement de génie logiciel DB-Main avec lequel a été construit un prototype d'outil d'aide à l'évolution. Cet outil permet notamment de générer automatiquement les programmes de conversion de la base de données à partir de la trace des opérations de modification des schémas conceptuel ou logique de la base de données. Il aide aussi le programmeur à modifier les programmes d'application en conséquence.| If the recent DBMS technologies consider the problem of databases schema evolution, standard Information Systems in use raise hard problems when evolution is concerned. This work studies these problems in the current developer context. It gives a complete typology of modifications and analyses the evolution of systems and its impact on the data structures, data and programs through typical strategies. The document introduces the DB-Main CASE environment, with which an evolution tool prototype has been developed. This tool can automatically generate the conversion programs for the database from the operational trace of the conceptual and logical schema modifications. It can also help the programmer to modify the application programs.

<p>Software engineering tools are being used in the industry in order to improve the productivity and the quality of the software development process. The properties of those tools are being perceived to be unsatisfactory. For example, researchers have found that some problems are due to deficient integration among the tools. Furthermore, a continuing problem is that there is a gap between the IT education and real demand of tool-skills form IT industry. Consequently, knowledge is needed of the properties of software development tools as well an understanding of demanded tool-skill from the industry. </p><p>The purpose of this study is to survey commercial software development environment (SDEs) that are used today in professional software engineering and discuss their advantages adn disadvantages. A secondary goal of the study is to identify the actual requirements from the industry on the IT-education. </p><p>A questionnaire was sent out to 90 software developers and IT managers of 30 IT companies in Sweden. The results of the survey show that IT companies, for most part, use SDEs from commercial software vendors. Respondents report that common problems of the SDEs are the following: bad integration among the tools, problems to trace software artifacts in the different phases of the programming cycle, and deficient support for version control and system configuration. Furthermore, some tools are difficult to use which results in a time-consuming development process. </p><p>We conclude that future software development environments need to provide better support for integration, automation, and configuration management. Regarding the required tool-skills, we believe that the IT education would gain from including commercial tools that cover the whole software product lifecycle in the curriculum.</p>

O objetivo principal desta dissertação explora alguns aspectos relacionados ao desenvolvimento colaborativo de sistemas de informação na Internet. E apresentado o Editor Diagramático na Internet (EDI), que suporta a especificação colaborativa de aplicações. Este editor utiliza tecnologia e funcionalidade dos hiperdocumentos, oferecendo características como: compartilhamento de informações, colaboração entre vários autores e varias visões dos dados conceituais armazenados. EDI foi implementado utilizando a linguagem de programação Java e projetada de forma genérica para permitir a criação de editores de diferentes notações diagramáticas. Este trabalho propõe a utilização de anotações em documentos de desenvolvimento de sistemas de informação na Internet. Estas anotações auxiliam no desenvolvimento colaborativo de sistemas, tornando o processo mais colaborativo e com um produto resultante de qualidade superior. As anotações estão baseadas em dois tipos de usuários: o usuário proprietário, responsável pela criação do documento, e o usuário colaborador, que inclui anotações nos documentos. Anotações (identificadas por uma especifica cor) podem ser de inclusão, alteração, remoção de conceitos (visões) ou registro de comentários. / The main goal of this work is to explore some issues related to collaborative development of information systems on the Internet. A Diagrammatic Editor on the Internet (EDI) that supports collaborative specification of applications is described. This editor uses hyperdocument technology and funcionalities, offering features such as information sharing, collaboration between several authors, multiple views of the stored conceptual data, among others. EDI was implemented using the Java language, and designed with the purpose of being generic to enable the easy creation of specific editors for different diagrammatic notations. The use of annotations for the joint development of information systems on the Internet is proposed. With these annotations the development process becomes more collaborative and the quality of the final product may increase. Annotations are based on two types of users: the owner, who is an author responsible for the creation of a document, and the collaborator, who makes annotations on those documents. Annotations (identified by one specific colour) can be of inclusion, change and removal of concepts (views), or recording of comments.
