PIKM workshop offers to Ph.D. students the possibility to bring their work to an international and interdisciplinary research community, and create a network of young researchers to exchange and develop new and promising ideas. Similarly to the CIKM, ...

Variety in Big Data means we have a wide range of data types and sources: e.g. File systems and database systems co-exist for decades as two popular data-accessing interfaces. This work is to unify these two interfaces by presenting a Data Interface All-...

Distributed database systems represent an essential component of modern enterprise application architectures. If the overall application needs to provide reliability and availability, the database has to guarantee these properties as well. Entailing non-...

From social networking websites to bank transactions, we interact with data-intensive applications every day. Such applications are typically hosted on an application server that interacts with a database server to manipulate persistent data. To make ...

The number of papers on database system education has been close to zero at recent conferences. As database systems are a fundamental part of computer science curricula this comes as a surprise. The apparent draught in new ideas in database system ...

Promoting sustainability, critical thinking, and ethical awareness are goals that appear in the vision statements of the majority of universities in the United States nowadays. One way of achieving these goals is by increasing the ecological literacy (...

The PIKM workshop gives Ph.D. students an opportunity to present their dissertation proposals at a global stage. Similarly to the CIKM, the PIKM workshop covers a wide range of topics in the areas of databases, information retrieval and knowledge ...

In cloud environments, resources should be acquired and released automatically and quickly at runtime. Thereby, the implementation of traditional query optimization strategies in cloud platforms can have a poor performance, because they cannot predict ...

Testing data-intensive systems is paramount to increase our reliance on e-governance services. An incorrectly computed tax can have catastrophic consequences in terms of public image. Testers at Norwegian Customs and Excise reveal that faults occur from ...

In this paper, we propose to develop a framework to analyze the monetary cost of running database systems in the public cloud. The framework offers guidelines and methodologies in analyzing and estimating monetary cost of database systems. It consists ...

The rise of big data and cloud computing significantly changed the database market. Here, the authors describe how developers decomposed the traditional database system and questioned the classical three-tier system architecture.

As high-performance computing approaches exascale, the existing I/O system design is having trouble keeping pace in both performance and scalability. We propose to address this challenge by adopting database principles and techniques in parallel I/O ...

In the paper, we initialize the open project for ontology of rough sets and related fields called RoSetOn. In our opinion, there is a need in rough set society to create such ontology. This paper tries to open discussion and actions concerning this task ...

In the multicore era, database systems are facing new challenges to exploit parallelism and scale query performance on new processors. Taking advantage of multicore, however, is not trivial and goes far beyond inserting parallel constructs into ...

An important component of the European energy market system is an automated bidding system. We present a database-driven system which handles bid posting, error-checking and acknowledgement, based on a client-server paradigm. The bids are posted through ...

Current methods for developing software for mobile devices don't account for input/output (I/O) options when design decisions are made. I/O needs are typically addressed in an ad hoc manner, and inexperienced application developers are not accustomed to ...

This paper describes a collaboration between computer science and journalism students and professors at our small, primarily undergraduate college, and a large metropolitan newspaper. Our students' work was a catalyst for a hard-hitting series of ...

The PIKM workshop focuses on papers consisting mainly of the Ph.D. dissertation proposals of doctoral students. A wide range of topics on any area in databases, information retrieval and knowledge management are presented at this workshop. The areas of ...

Database system development is a code intensive, time consuming task for a developer. It is suggested that the underlying database and program code can be inferred from a well designed Graphical User Interface (GUI). GUI analysis DEvelopment (GUIDE) is ...

Beyond using XML as a message format, more and more companies are storing XML data permanently in a database. Database researchers and vendors alike have spent a lot of effort on designing, studying, and implementing XML database technology. In this ...
