Normalized Systems are a model-driven development technique focusing on evolvability and sustainability of resulting enterprise information systems. It applies well-defined principles to create a fine-grained modular structure while limiting combinatorial effects. The systems are generated (or, more precisely, expanded) from models of so-called NS...

Functional requirements on a software system are traditionally captured as text that describes the expected functionality in the domain of a real-world system. Natural language processing methods allow us to extract the knowledge from such requirements and transform it, e.g., into a model. Moreover, these methods can improve the quality of the requ...

Normalised System Theory provides a theoretical foundation on how to build software with respect to change over time. An advanced development platform has been built by the NSX company to build Normalised Systems in practice, from modelling tools to implementation. However, there is a lack of support for modelling user interfaces in the platform, s...

During the last decade, there was a huge shift in the problem of evolvability. However, still, the problem remains fully unresolved. Our focus is to improve evolvability in the domain of data stewardship planning. The main problem causing the low evolvability is the use of traditional documents – data management plans. Our approach redesigns the wo...

Moore's law states that the number of transistors on a chip will double every two years. A similar force appears to drive the progress of information technology (IT). IT companies tend to struggle to keep up with the latest technological developments, and software solutions are becoming increasingly outdated. The ability for software to change easi...

Normalized Systems (NS) theory describes how to design and develop evolvable systems. It is applied in practice to generate enterprise information systems using NS Expanders from models of NS Elements.
