2006 ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP)  
This model is used to develop an OLAP application for navigation into a hypercube integrating various functional dimension versions for the calculus of descriptors in a medical use case.  ...  One of the problems when integrating multimedia data as facts in a multidimensional model is to deal with dimensions built on descriptors that can be obtained by various computation modes on raw multimedia  ...  In Section 2 we provide some definitions for OLAP and multidimensional models, and for multimedia data warehouses.  ...

An Architecture Framework for Complex Data Warehouses [article]

Jérôme Darmont, Omar Boussaid, Jean-Christian Ralaivao, Kamel Aouiche
2007 arXiv   pre-print
Nowadays, many decision support applications need to exploit data that are not only numerical or symbolic, but also multimedia, multistructure, multisource, multimodal, and/or multiversion.  ...  In this paper, we first propose a precise, though open, definition of complex data. Then we present a general architecture framework for warehousing complex data.  ...  warehouse; and data modeling and storage.  ...

Integration and dimensional modeling approaches for complex data warehousing

O. Boussaid, Adrian Tanasescu, Fadila Bentayeb, Jérôme Darmont
2006 Journal of Global Optimization  
A data warehousing approach is often adopted to prepare data for relevant analysis. Data integration and dimensional modeling indeed allow the creation of appropriate analysis contexts.  ...  Complex data are then stored in XML documents generated by a piece of software we designed. The second important phase we address is the preparation of data for dimensional modeling.  ...  The choice of a data model for a complex data warehouse requires more than only data sources and analysis goals.  ...

Multiversion locking protocol with freezing for secure real-time database systems

Chanjung Park, Seog Park, S.H. Son
2002 IEEE Transactions on Knowledge and Data Engineering  
In order to show that our protocol provides a higher degree of concurrency than existing multiversion protocols, we define a new serializability for multiversion concurrency control, called FR-serializability  ...  In this paper, we propose a new multiversion concurrency control protocol that ensures that both security and real-time requirements are met. The proposed protocol is primarily based on locking.  ...  His major research areas are database security, real-time systems, data warehouse, digital library, multimedia database systems, role-based access control, and Web database.
