IT industry all time is looking for ways to improve software development productivity as well as the quality and longevity of the software that it creates. OMG announced Model Driven Architecture as its strategic direction. It is software development methodology that provides new viewpoint in software development process. The modeling of problem domain and model transformation are key elements of MDA architecture and they are analyzed in this work using OMG specifications and other resources. The purpose of this work is to evaluate benefits of MDA framework in software development process. The new MDA framework is developed according to the results of MDA architecture analysis. Experimental usage of new MDA framework concentrates on productivity of software development process, automation of repeated tasks and required skill set of application developers.

Presented work covers one of the most important areas of OMG’s model driven architecture (MDA) – problems of object model transformations. Based on research of OMG specifications and other sources, author analyzes transformation process, states importance of modeling and metamodeling for designing of UML like modeling languages. Research work describes designed PIM ant PSM metamodels of aggregate systems. Structure and syntax of ATL and MTL model transformation languages was introduced. Author gives a short overview of model editors and graphical representation for these languages, created using EMF framework tools. Transformation languages have been compared. A result of experimental transformations was summarized by their qualitative and quantitative criteria. Advantages of hybrid ATL transformation language versus imperative MTL language were found. Experimental transformations were successfully produced and executed using ATL and MTL model transformation languages.

As transformações podem ser escritas por meio de linguagens como Query/View/Transformation (QVT), outro padrão do OMG. Como em linguagens de programação, pode-se fazer necessária a adição de funcionalidades que acabam se cruzando no código (como logging e rastreio, por exemplo), podendo resultar em cross-cutting concerns na transformação. Esse problema pode então ser enfrentado por meio do Paradigma Orientado a Aspectos. Presentemente, não encontramos soluções que aplicam, especificamente, aspectos para a solução de cross-cutting concerns em transformações escritas na linguagem QVT. Assim, nós propomos e desenvolvemos uma linguagem de aspectos para QVT, de nome AQVT, além de um compilador que realiza o weaving do código AQVT com o código original QVT. Utilizando-se de métricas sobre os programas QVT e a execução das transformações AQVT, realizamos um estudo empírico sobre a linguagem AQVT proposta. Identificamos nesse estudo que ocorre uma melhora fraca na qualidade de leitura e uma boa melhora na modularidade dos código QVT e AQVT, se comparado com uma transformação equivalente escrita puramente em QVT. Contudo, não foi possível realizar uma implementação completa de todas as funções do Paradigma de Aspectos e de alguns elementos da linguagem QVT em AQVT, deixando essas atividades como trabalhos futuros. / MDA (Model-Driven Architecture) is a standard specified by the Object Management group (OMG) that allows a developer to generate models from models by means of MDA Transformations, a set of functions that match and bind elements between source and target models. Transformations can be written in languages such as Query/View/Transformations Language (QVT), another OMG standard. As with programming languages, the addition of features in the code that cut through it (like logging and tracing) may cause cross-cutting concerns in the transformation. This problem can then be addressed through the use of the Aspect Oriented Paradigm. Currently, we could not find solutions that used Aspects for the specific problem of crosscutting concerns within QVT transformations. We proposed and developed an aspects language for QVT, named AQVT, along with a compiler that weaves both the QVT and AQVT codes into a single program. With the assistance of metrics applied to the QVT programs and the execution of AQVT code, we have performed an empirical research for the proposed QVT language. We identified that the quality of reading improved slightly and the modularity of the program increased, when comparing the code between two equivalent transformations (one with an AQVT module and the other without it). However, we were not able to completely implement all of the functions from the Aspects Paradigm nor some of the elements from the QVT language into AQVT and propose those activities as our future work.

Detta är en kandidatuppsats som presenterar ett arbete om berättande i spel och ett fokus på narratologiska och ludologiska berättartekniker. Narratologer och ludologer har länge varit oense om det sätt på vilket ett spel ska analyseras. Skillnaden mellan dessa två är att narratologer anser att spel ska analyseras som ett narratologiskt medie (som t.ex. böcker eller film) medan ludologer istället menar att spel ska analyseras genom spelmekanik (regler och spelarens interaktion med spelvärlden). I detta arbete presenteras olika sätt att använda berättande i spel och en tillämpning på detta gestaltas genom ett spel med en stegräknare skapat i form av en mobilapplikation

In this thesis we will examine a telecom industry case, where combining synchronous and asynchronous interfaces causes problems. A solution to the problem is being presented in form of an interface controller framework that is based on patterns of common functionality of interface controllers. The solution is implemented using four different implementation methods (Java, Erlang, XDE, Executable UML), and compared in lines of code, performance and throughput. / I rapporten undersöks ett fall i telekominudstrin, där kombinerandet av synkrona och asynkrona interface orsakar problem. En lösning på problemet är presenterat i form av ett framework för interface controllers som är baserat på mönster som beskriver den gemensamma funktionaliten i interface controllers. Lösningen är implementerad med hjälp av fyra olika implementeringsmetoder (Java, Erlang, XDE och Executable UML), där rader kod och prestanda jämförs. / pt00cbj@student.bth.se pt00psa@student.bth.se

The Model Driven Architecture is a proposition of the framework of software development process where main accent is put on system models, i.e. platform independent and platform dependent models, and transformations between them. Applying the MDA is related with preparation of these two types of assets. In the thesis, the EDOC and the EJB platform are considered as an examples of platform-independent and platform dependent models. In order to complete this picture, additionally transformations between these two models are required. The authors focus in the thesis on transformations. In particular, the authors present the transformation specification description, and specify set of transformations between the EDOC and EJB models. The transformations are narrowed to the subset of structural aspects of the EDOC models.
