Chip-Secured Data Access: Confidential Data on Untrusted Servers
- …The democratization of ubiquitous computing (access data anywhere, anytime, anyhow), the increasing connection of corporate databases to the Internet and the today's natural resort to Webhosting companies strongly emphasize the need for data confidentiality. Database servers arouse user's susp…

A Single-Phase Non-Blocking Atomic Commitment Protocol
- …Transactional standards have been promoted by OMG and X/Open to allow heterogeneous resources to participate in an Atomic Commitment Protocol (ACP), namely the two-phase commit protocol (2PC). Although widely accepted, 2PC is a blocking protocol and it introduces a substantial time delay (two phases…

Bitmap Based Algorithms For Mining Association Rules
- …: Discovery of association rules is an important problem in Data Mining. The classical approach is to generate all itemsets that have support (i.e., the fraction of transactions containing the itemset) above a user given threshold. Most existing algorithms aim at reducing the number of scans over th…

One-Phase Commit: Does it make sense?
- …Although widely used in distributed transactional systems, the so-called Two-Phase Commit (2PC) protocol introduces a substantial delay in transaction processing, even in the absence of failures. This has led several researchers to look for alternative commit protocols that minimize the time cost as…

On Finding a Memory Lower Bound for Query Evaluation in Lightweight Devices
- …Pervasive computing introduces data management requirements that must be tackled in a growing variety of lightweight computing devices. Personal folders on chip (e.g., healthcare folders on smartcards), networks of sensors (e.g., pollution sensors) and data hosted by autonomous mobile computers (e.g…

Graph View Modeling for a Technical Information System
- …Technical Information Systems often have to perform complex computations on voluminous graphs. The edges and nodes of these graphs are generally stored as complex objects in heterogeneous storage supports like databases and files and are manipulated by ad-hoc operators. In this paper, we use the con…

Database Graph Views: A Practical Model to Manage Persistent Graphs
- …Advanced technical applications like routing systems or electrical network management systems introduce the need for complex manipulations of large size graphs. Efficiently supporting this requirement is now regarded as a key feature of future database systems. This paper proposes an abstraction mec…

Client-Based Access Control Management for XML Documents
- …The erosion of trust put in traditional database servers and in Database Service Providers, the growing interest for different forms of data dissemination and the concern for protecting children from suspicious Internet content are different factors that lead to move the access control from ser…
