    A Data Browsing From Various Sources Driven by the User's Data Models

    There are many various data extracting and browsing tools available that provide working with a physical database (relational, object-oriented, RDF, etc.). The authors propose to drive the browser by a logical data model that serves as a bridge between browser and physical data sources. This approach allows a creating so...

    Integration of Change and Evolution in the Lifecycle of SMEs Information Systems

    Today's software enterprise systems continue to suffer from symptoms like aging and the lack of evolution capabilities. One of the major reasons for this problem is that the future maintenance and evolutions are undervalued during traditional software systems implementation. The best way to overcome the problem of software aging and...

    Business IT Alignment from Business Model to Enterprise Architecture

    Information Technology is becoming more and more ubiquitous, changing the way the authors exchange information and extending the realm of possibilities. In this paper, they show how business model modeling can be connected to IT infrastructure, drawing parallels from enterprise architecture models such as ArchiMate. They then show how the...

    Prototype for Traversing and Browsing Related Data in a Relation Database

    People who develop, test and maintain information systems often have to inspect the content of databases to make sure that data have been stored correctly or to find errors in the data. The most popular RDBMS and specialised database management tools usually offer single-table browsing. Sometimes SQL requests will be...

    Using the Sponsor-User-Programmer Model to Improve the Testing Process

    This paper describes the Sponsor-User-Programmer (SUP) model, which offers simplified and structured views of certain aspects of software requirements. The principles of the model are based on the idea that there are three major players or stakeholders in software development - the client or sponsor, the user, and the programmer...

    Use of Design Patterns in PHP-Based Web Application Frameworks

    It is known that design patterns of object-oriented programming are used in the design of Web applications, but there is no sufficient information which data patterns are used, how often they are used, and the level of quality at which they are used. This paper describes the results concerning the...

    OWLGrEd: A UML Style Graphical Notation and Editor for OWL 2

    There have been several attempts to visualize OWL ontologies with UML style diagrams. Unlike ODM approach of defining a UML profile for OWL, the paper proposes an extension to UML class diagrams (hard extension) that allows a more compact OWL visualization. The compactness is achieved through the native power of...

    An Extension of Multi-Layer Perceptron Based on Layer-Topology

    There are a lot of extensions made to the classic model of multi-layer perceptron (MLP). A notable amount of them has been designed to hasten the learning process without considering the quality of generalization. The paper proposes a new MLP extension based on exploiting topology of the input layer of...
