Modeling Multiple Representations into Spatial Data Warehouses: a Uml-based Approach

چکیده

Creating database schemas that include complex geometries and that take into account map generalization as well as multiple geometric representations is quite a challenge. The created schemas are either too complex to become useful, too large to be usable, too detailed to be checked with the overall integrity in mind, or even too labor-intensive to even be created or edited. This paper presents a method and a tool that has been used with success in modeling generalization and multiple representation for a spatial data warehouse. RÉSUMÉ: La création de schémas de bases de données qui incluent des géométries complexes et qui tiennent compte des processus de généralisation aussi bien que des représentations géométriques multiples représente tout un défi. Les schémas ainsi créés sont soit trop complexes pour être utiles, trop volumineux pour être utilisables, trop détaillés pour être vérifiables dans une optique d'intégrité générale du schéma, ou même trop exigeants à produire ou éditer. Cet article présente une méthode et un outil qui ont été utilisés avec succès pour la modélisation de la généralisation cartographique et la représentation multiple dans le cadre de création d'un entrepôt de données spatiales.

A UML profile for multidimensional modeling in data warehouses

The multidimensional (MD) modeling, which is the foundation of data warehouses (DWs), MD databases, and OnLine Analytical Processing (OLAP) applications, is based on several properties different from those in traditional database modeling. In the past few years, there have been some proposals, providing their own formal and graphical notations, for representing the main MD properties at the con...

Robust representation for conversion UML class into XML Document using DOM

This paper presents a Framework for converting a class diagram into an XML structure and shows how to use Web files for the design of data warehouses based on the classification UML. Extensible Markup Language (XML) has become a standard for representing data over the Internet. We use XSD schema for define the structure of XML documents and validate XML documents. A prototype has been developed...

The use of UML to design agricultural data warehouses

Recent research works propose to use the Unified Modeling Language (UML) to design data warehouses. First, the paper overviews these recent UML-based techniques. We show that UML can help system designers to build a data warehouse model. This type of model aims to describe the different analysis dimensions of the data. Second, we will also present different UML-based tools used during a project...

A UML Based Approach for Modeling ETL Processes in Data Warehouses

Data warehouses (DWs) are complex computer systems whose main goal is to facilitate the decision making process of knowledge workers. ETL (Extraction-Transformation-Loading) processes are responsible for the extraction of data from heterogeneous operational data sources, their transformation (conversion, cleaning, normalization, etc.) and their loading into DWs. ETL processes are a key componen...

Developing a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information

With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
