The Orion Uncertain Data Management System

Sarvjeet Singh, Chris Mayfield, Sagar Mittal, Sunil Prabhakar, Susanne E. Hambrusch, Rahul Shah
2008 International Conference on Management of Data  
Both discrete and continuous pdfs are handled in a natural and accurate manner. The system uses standard SQL with only minimal modifications.  ...  Orion is a state-of-the-art uncertain database management system that extends the relational model to include probabilistic uncertain data as first call data types.  ...  This in turn provides additional opportunities to the query engine for indexing and optimization. One motivating example is a data cleaning system that automatically detects and corrects errors.  ...

ConQueSt: a Constraint-based Querying System for Exploratory Pattern Discovery

F. Bonchi, F. Giannotti, C. Lucchese, S. Orlando, R. Perego, R. Trasarti
2006 22nd International Conference on Data Engineering (ICDE'06)  
ConQueSt is a constraint-based querying system devised with the aim of supporting the intrinsically exploratory nature of pattern discovery.  ...  It provides users with an expressive constraint-based query language which allows the discovery process to be effectively driven toward potentially interesting patterns.  ...  Queries can be defined directly using the query language, or alternatively, using a graphical query generator that helps users in navigating the source dataset and in defining suitable parameters and constraints  ...

Third-generation database system manifesto

1990 SIGMOD record  
In this paper we consider the characteristics that must be satisfied by the next generation of data managers, which we call third generation database systems.  ...  We call the older hierarchical and network systems first generation database systems and refer to the current collection of relational systems as the second generation.  ...  In this paper, we present the three basic tenets that should guide the development of third generation systems.  ...

The user draws a graphic representing the properties results have to verify. Keyword Visual query language, Graph manipulations, Geographical Information System S. Spaccapietra et al.  ...  In this paper we present network manipulations with a visual query language for a geographical database. A query is defined with a visual expression defined with a Query-By-Example approach.  ...  The drawing process automatically generates these operators. A query is graphically built from a combination of metaphores and operators.  ...
