Uncertain data are inherent in some important applications, such as environmental surveillance, market analysis, and quantitative economics research. Due to the importance of those applications and the rapidly increasing amount of uncertain data ...

Object/Relational Mapping (ORM) provides a methodology and mechanism for object-oriented systems to hold their long-term data safely in a database, with transactional control over it, yet have it expressed when needed in program objects. Instead of ...

We demonstrate XRPC, a minimal XQuery extension that enables distributed querying between heterogeneous XQuery engines. The XRPC language extension enhances the existing concept of XQuery functions with the Remote Procedure Call (RPC) paradigm. XRPC is ...

The goal of the Demaq project is to investigate a novel way of thinking about distributed applications that are based on the asynchronous exchange of XML messages. Unlike today's solutions that rely on imperative programming languages and multi-tiered ...

This demo presents a privacy-preserving aggregate location monitoring system, namely, TinyCasper, in which we can monitor moving objects in wireless sensor networks while preserving their location privacy. TinyCasper consists of two main modules, in-...

The UQBE is a mashup tool for non-programmers that supports query-by-example (QBE) over a schema made up by the user without knowing the schema of the original sources. Based on automated schema matching with uncertainty, the UQBE system returns the ...

We present SchemaScope, a system to derive Document Type Definitions and XML schema from a corpus of sample XML documents. Tools are provided to visualize, clean and refine existing or inferred schemas. A number of use cases illustrate the versatility ...

Orion is a state-of-the-art uncertain database management system with built-in support for probabilistic data as first class data types. In contrast to other uncertain databases, Orion supports both attribute and tuple uncertainty with arbitrary ...

We propose to demonstrate SEMMO, a consistency server for MMOs. The key features of SEMMO are its novel distributed consistency protocol and system architecture. The distributed nature of the engine allows the clients to perform all computations locally;...

Microsoft SQL Server 2008 adds built-in support for 2-dimensional spatial data types for both planar and geodetic geometries to address the increasing demands for managing location-aware data. SQL Server 2008 also adds indexing capabilities that, ...

Agents manning a service desk have the unenviable task of satisfying multiple conflicting objectives. Specifically, businesses require the agents to meet pre-specified customer satisfaction levels while keeping the cost of operations low or meeting ...

In this paper, we present Spade - the System S declarative stream processing engine. System S is a large-scale, distributed data stream processing middleware under development at IBM T. J. Watson Research Center. As a front-end for rapid application ...

Partitioning is typically employed on large-scale data to improve manageability, availability, and performance. However, for tables connected by a referential constraint (capturing a parent-child relationship), the current approaches require ...

The integration of the .NET Common Language Runtime (CLR) into the SQL Server DBMS enables rich business logic written in modern .NET languages to run close to the data. Database application developers can write business logic as functions, stored ...

Several XML DBMSs support XQuery and/or SQL/XML languages, which are based on navigational primitives in the form of XPath expressions. Typically, these systems either model each XPath step as a separate query plan operator, or employ holistic ...
