Hermes – a framework for location-based data management

by Nikos Pelekis, Yannis Theodoridis, Spyros Vosinakis, Themis Panayiotopoulos - In EDBT’06 , 2006
"... Abstract. The aim of this paper is to demonstrate Hermes, a robust framework capable of aiding a spatio-temporal database developer in modeling, constructing and querying a database with dynamic objects that change location, shape and size, either discretely or continuously in time. Hermes provides ..."

.g. Location-Based Services- LBS). The produced type system is packaged and provided as a data cartridge using the extensibility interface of Oracle10g. The offspring of the above framework extends PL/SQL with spatiotemporal semantics. The serviceableness of the resulting query language is demonstrated

"... Constraints provide a flexible and uniform way to represent diverse data capturing spatio-temporal behavior, complex modeling requirements, partial and incomplete information etc, and have been used in a wide variety of application domains. Constraint databases have recently emerged to deeply integr ..."

parts, showing how the framework models two different representations of spatial data. In the first part, we employ our framework on top of Spatial Cartridge of Oracle8. In the second part, we describe a mapping on linear constraints. The second application shows how the model is able to represent

Novel knowledge discovery tools in industrial applications

by Zdeněk Kouba, Kamil Matoušek, Petr Mikšovský - In Proc. of the Workshop on Intelligent Methods for Quality Improvement in Industrial Practice , 2002
"... This paper is focused on available IT tools suitable for predictive data mining in media (of any kind) distribution networks. Current geographical information systems (GIS) handle large amounts of geographical data that are usually stored in relational databases. GIS systems provide a possibility of ..."

of spatial query evaluation on this data. As spatial queries are usually very expensive form the computational point of view, major database vendors developed special plug-ins in order to make retrieval of geographical data more efficient. For example, Oracle offers their Spatial Cartridge based on quad

(Fundamentals of Database Systems, Third Edition)

by unknown authors , 2007
"... As the use of database systems has grown, users have demanded additional functionality from these software packages, with the purpose of making it easier to implement more advanced and complex user applications. Object-oriented databases and object-relational systems do provide features that allow u ..."

structures and indexing methods can be implemented to improve the performance of these common features. These features can then be implemented as abstract data type or class libraries and separately purchased with the basic DBMS software package. The term datablade has been used in Informix and cartridge

ISPRS SIPT CONCEPT AND REALIZATION OF FEDERATED SPATIAL DATABASE

by Jianya Gong, Hanjiang Xiong, Yandong Wang, Lite Shi
"... Geographic information systems manage a large volume of spatial data. We often use it to solve some problems such as urban planning and land use management. Interoperability of GIS is the ability to access spatial data and associated services in a distributed and heterogeneous processing environment ..."

component spatial databases distributed in the LAN, which include graphic databases, DEM databases and image databases built with Oracle8i spatial cartridge, SQL Server 7.0 and GeoStar 3.0 file system. 1.

Matching Cartographic Objects in Spatial Databases

by Daniela Mantel, Udo Lipeck - In: Proceedings of the XX th ISPRS Congress, Comm. IV , 2004
"... Nowadays cartographic objects of different resolutions are hold in different coexisting databases. This implies an extensive amount of work for updating an object in all resolutions. One way to reduce this is to build a multi-resolution database which holds and links different representations of the ..."

based on Oracle9i (with the spatial data cartridge). The enclosing object matching process is supported by a graphical user interface utilizing stored database procedures for the mentioned steps and rules. KURZFASSUNG: Kartographische Objekte verschiedener Maßstäbe werden in unterschiedlichen

A Middleware Approach to Temporal Query Processing

by Giedrius Slivinskas , 2001
"... Time-referenced, or temporal, data occur pervasively in most real-world databases. Recent advances in temporal query languages show that such applications may benefit substantially from a database management system (DBMS) with built-in temporal support. The potential benefits are several: applicatio ..."

-related data types, e.g., the Informix TimeSeries DataBlade and the Oracle TimeSeries cartridge, and extensibility facilities that enable the user to define new, e.g., temporal, data types. However, temporal support is needed that goes beyond data types and extends the query language itself, as well
