Creating and maintaining an enterprise architecture model that is both up-to-date and accurate is a difficult task due to the size and complexity of the models and the dispersed nature of EA information in organizations. In current EA maintenance processes, the models are maintained manually with only little automation, which is a time consuming task.(More)
Enterprise Architecture Management (EAM) is the practice of modeling the business and IT artifacts in an enterprise and relating them with each other. By documenting these interdependencies between business and the supporting IT, strategic decisions can be made towards a planned and consolidated enterprise architecture that matches the business needs.(More)
Osmoregulatory uptake of glycine betaine in whole cells of Corynebacterium glutamicum ATCC 13032 (wild type) was studied. The cells actively take up glycine betaine when they are osmotically shocked. The total accumulation and uptake rate were dependent on the osmotic strength of the medium. Kinetic analysis revealed a high-affinity transport system (Km,(More)
Regulation of glnA expression and glutamine synthetase I activity was analyzed in Corynebacterium glutamicum. Transcription is regulated by the global repressor protein AmtR, essential for derepression of glnA transcription are GlnK and uridylyltransferase, key proteins of the C. glutamicum nitrogen regulatory system. Glutamine synthetase I activity is(More)
Over the past decade Enterprise Architecture (EA) management matured to a discipline commonly perceived as a strategic advantage. Among others, EA management helps to identify and realize cost saving potentials in organizations. EA initiatives commonly start by documenting the status-quo of the EA. The respective management discipline analyzes this(More)
Over the past decade, Enterprise Architecture (EA) management emerged to a mature discipline commonly applied to realize cost saving potentials while increasing effectiveness of IT in organizations. Typically, EA management starts by documenting the current state in an EA model and deriving future planned states heading towards an optimized EA. In practice,(More)
This contribution presents GEMSjax – a web-based metamodeling tool for the collaborative development of domain specific languages. By making use of modern Web 2.0 technologies like Ajax and REST services, the tool allows for simultaneous web browser-based creation/editing of metamodels and model instances, as well as secure remote model access via REST,(More)
Maintaining a high quality enterprise architecture (EA) model that is up-to-date and consistent is a difficult but crucial task. The reasons for this difficulty are the size and complexity of EA models, frequent changes in the architecture and the challenge of collecting EA data from different stakeholders in large organizations. In our research project(More)
