A Decision Guidance Management System (DGMS) is a productivity platform for fast development of applications that require a closed-loop data acquisition, learning, prediction, and decision...
Large Constraint Joins and Disjoint Decompositions (2007)
Alexander Brodsky, Victor E. Segal
This paper is devoted to the problem of evaluation of a conjunction of N disjunctions of linear constraints in R d (constraint join), which is a common constraint database operation. Existing methods...
The C 3 Constraint Object-Oriented Database System (2007)
Alexander Brodsky, Victor E. Segal, Pavel A. Exarkhopoulo
Constraints provide a flexible and uniform way to conceptually represent diverse data capturing spatio-temporal behavior, complex modeling requirements, partial and incomplete information etc, and...
Regression databases: Probabilistic querying using sparse learning sets (2006)
We introduce Regression Databases (REDB) to formalize and automate probabilistic querying using sparse learning sets. The REDB data model involves observation data, learning set data, views...
Growth Processes on Formulas and Reversible Circuits by (2003)
Alexander Brodsky, C Alex, Er Brodsky
Among their many uses, growth processes have been used for constructing reliable networks from unreliable components (Moore and Shannon, 1956) and deriving complexity bounds of various families of...
Secure databases: Constraints, inference channels, and monitoring disclosures (2000)
Alexander Brodsky, Csilla Farkas, Sushil Jajodia
This paper investigates the problem of inference channels that occur when database constraints are combined with non-sensitive data to obtain sensitive information. We present an integrated security...
Toward practical query evaluation for constraint databases (1997)
Alexander Brodsky, Michael J. Maher
Linear constraint databases (LCDBs) extend relational databases to include linear arithmetic constraints in both relations and queries. A LCDB can also be viewed as a powerful extension of linear...
Logical Design for Temporal Databases with Multiple Temporal Types (1997)
X. Sean Wang, Claudio Bettini, Alexander Brodsky, Sushil Jajodia
The purpose of good database logical design is to eliminate data redundancy and insertion and deletion anomalies. In order to achieve this objective for temporal databases, the notions of temporal...
Logical design for temporal databases with multiple granularities (1997)
X. Sean Wang, Alexander Brodsky, Sushil Jajodia
The purpose of good database logical design is to eliminate data redundancy and insertion and deletion anomalies. In order to achieve this objective for temporal databases, the notions of temporal...
The C 3 Constraint Object-Oriented Database System (1996)
Alexander Brodsky, Victor E. Segal, Pavel A. Exarkhopoulo
Constraints provide a exible and uniform way to conceptually represent diverse data capturing spatio-temporal behavior, complex modeling requirements, partial and incomplete information etc, and have...
On approximation-based query evaluation, expensive predicates and constraint objects (1995)
Alexander Brodsky, X. Sean Wang
The use of approximations of complex, possibly nested collection, objects can considerably improve the processing of queries with expensive predicates. The improvement is gained by (1) avoiding much...
Separability of Polyhedra for Optimal Filtering of Spatial and Constraint Data (1995)
Alexander Brodsky, Catherine Lassez, Jean-louis Lassez, Michael J. Maher
The filtering method considered in this paper is based on approximation of a spatial object in d-dimensional space by the minimal convex polyhedron that encloses the object and whose facets are...
Constraint Database Approach to Spatio-Temporal Data Fusion and Sensor Management (1995)
Theresa Aschenbrenner Alexander, Alexander Brodsky, Yoram Kornatzky
Proposed is a novel, unified and flexible approach to implementing systems dealing with fusion of spatial and temporal data and the related problem of sensor management. The thesis of this paper is:...

The use of approximations of complex, possibly nested collection, objects can considerably improve the processing of queries with expensive predicates. The improvement is gained by (1) avoiding much...
The LyriC language: Querying constraint objects (1995)
Alexander Brodsky, Yoram Kornatzky
Proposed in this paper is a novel data model and its language for querying object-oriented databases where objects may hold spatial, temporal or constraint data, conceptually represented by linear...
The LyriC Language: Querying Constraint Objects (1994)
Alexander Brodsky, Yoram Kornatzky
Proposed in this paper is a novel data model and its language for querying object-oriented databases where objects may hold spatial, temporal or constraint data, conceptually represented by linear...
