An Approach to Data Quality Evaluation
2018
This research proposes a new approach to data quality evaluation comprising 3 aspects: (1) data object definition, which quality will be analyzed, (2) quality requirements specification for the data object using Domain Specific Language (DSL), (3) implementation of an executable data quality model that would enable scanning of data object and detect its shortages. Like the Model Driven Architecture (MDA) the data quality modelling is divided into platform independent (PIM) and platform-specific (PSM) models. PIM comprises informal specifications of data quality, PSM describes implementation of data quality model, thus making the data quality model executable. The approbation of the proposed…
Activity typologies as a design model for the ubiquitous detection of daily routines
2018
Emerging technologies open up new visions and business potential for systems design and development in the areas of wellbeing and health. New technologies enable the detection of human performance and early changes in physical and cognitive functioning, making it possible to monitor an older person’s wellbeing. This kind of technology or service sets significant requirements for design, as design concepts must be able to capture the complexity of people’s daily lives in terms of activities and environments. Technology itself is “blind” unless designers can adapt it to human life. There is thus a distinct need for comprehensive design and development models that generate adequate human requi…
Graph grammar engineering: A software specification method
1987
Graphs as conceptual data models are accepted and used in a wide range of different problem areas. Giving some examples we outline common aspects for modeling complex structures by graphs. We present a formal frame-work based on graph grammars to specify graph classes and the corresponding graph manipulations. We show that such a specification can be written in a systematic, engineering-like manner. This is achieved by an extension of the known programmed, attributed graph grammars. Node-set operators are introduced to facilitate graph queries. Concepts like abstraction, decomposition, refinement, parameterization, and integration have been adopted from software engineering to yield a compr…
A speech-act-based office modeling approach
1988
In this paper methods and principles that help to analyze offices as systems of communicative action are explored. In communicative action, office agents create commitments through symbolic means. A SAMPO (Speech-Act-based office Modeling aPprOach), which studies office activities as a series of speech acts creating, maintaining, modifying, reporting, and terminating commitments, is presented. The main steps and methods in the office system specification are outlined and their application illustrated through a simple example. In the final section advantages and disadvantages in the SAMPO are noted and some research directions for the future are suggested.
Towards Integrated Computer Aided Systems and Software Engineering Tool for Information Systems Design
1996
The paper starts with a brief overview of the current situation in the world of CASE tools for information systems. Then there follows the outline of the basic ideas and principles of integrated CASE tool GRADE. The most outstanding characteristics of GRADE are that the tool is based on a unified specification language GRAPES and that it supports all information system development phases including analysis, requirements specification, design and implementation.
