GeneDBase is a part of a research project titled “Creating a genetic database of selected species of mammals in the Czech Republic to be used for sustainable transport development”. The aim of the research project is to assess the impact of roads on the fragmentation of animal populations and their genetic variability. Further, the objective is to create a genetic database of mammals comprising...

This paper presents an integrated rule-based data mining system that is capable of creating rulebased classifiers with web-based user interface from data sets provided by end users. It provides a streamlined integration of three technologies, namely, database systems, machine learning systems , and rule-based systems. Rules generated by the system are based on rough set theory. Thus, it is capa...

I’ll illustrate the factors and the strategies with a hypothetical project. In this project, assume you are the project manager for a bank that is creating a Web application that allows homeowners to apply for a home equity loan on the Internet. You have two component vendors. You buy a COTS database management system from one vendor. You hire an outsourced custom development organization to de...

In the Heraclitus paradigm, a delta value or more simply, delta, is a concrete value that corresponds to a difference between database states. This paper presents the Heraclitus[OO] (abbreviated H2O) DBPL, which provides a syntax and semantics for working with deltas in the context of object-oriented databases. The paper also considers the use of deltas in connection with detecting conflict bet...

This paper presents the design and implementation of a Health Ontology Generator (HOG) using a health database such as Microsoft Access or SQL Server. The development of the ontology generator involves building methods for creating and reading the ontology. This research performs both these tasks. In generating the ontology, database tables are treated as classes, fields as functional propertie...

Geolocalized databases are becoming necessary in a wide variety of application domains. The manual creation of such databases is an expensive operation which stimulated the interest for the automation of their construction, by mining geographic information from the Web. In this article, we present and evaluate a new automated approach for creating a geographical database. Our technique uses Wik...

Intracellular processes in living organisms are described by metabolic models. A visualization of metabolic models assists interpretation of data or analyzing results. We introduce the visualization tool DaViMM creating personalized graphical representations of metabolic networks for model comparison or the display of measurements or analyzing results. The tool is coupled to a relational databa...

Models of plant architecture allow us to explore how genotype environment interactions effect the development of plant phenotypes. Such models generate masses of data organised in complex hierarchies. This paper presents a generic system for creating and automatically populating a relational database from data generated by the widely used L-system approach to modelling plant morphogenesis. Tech...

In this case study we attempt to visualize a real-world dataset consisting of 600 recently published information visualization papers and their references. This is done by first creating a global layout of the entire graph that preserves any cluster structure present. We then use this layout as a basis to define a hierarchical clustering. The clusters in this hierarchy are labelled using keywor...

In an object-oriented database management system built in the object-descriptor architecture, there is a concern about cached object-descriptors (CODs) filling up the client object cache space and, consequently, failing a database transaction. This phenomenon occurs especially during the data loading which keeps creating new objects in the object cache space. In this paper, we reexamine the str...
