    LOS GATOS, Calif., Sept. 17 /PRNewswire/ -- Red Brick(TM) Systems, Inc.
(Nasdaq: REDB), The Data Warehouse Company(TM), and ALTA Analytics, Inc. today
announced plans to provide data mining solutions for insurance, government and
commercial applications that combine ALTA's specialized data analysis
and information visualization applications with Red Brick Warehouse,
Red Brick's data warehouse relational database.
        The ALTA/Red Brick data mining solutions will enable analysts
to more quickly and efficiently determine patterns, trends and targets
from within their data in order to assist loss prevention, revenue
collection, corporate security and fraud units in commercial organizations and
government agencies.
        ALTA develops and markets the NETMAP(R) system and related
technology.  NETMAP is an advanced data analysis and information
visualization software system that can determine links, networks and emerging
patterns in data.  Red Brick is a leading provider of relational database
products and service specialized for data warehouse and decision support
applications.
        "We're pleased to be able to provide a data warehouse RDBMS that
efficiently supports the demanding needs of ALTA's data mining, analysis and
visualization software," said Peter Grey, manager of worldwide channels for
Red Brick.  "The combination of Red Brick's database technology with ALTA's
successful data analysis solutions gives users an edge in quickly targeting
trends, patterns and anomalies in their data."
        "Our analytical applications and commercial solutions require a
superior underlying technology base to be able to manage the complexities of
visual analysis and data mining processes," said Rob Winner, vice president
at ALTA Analytics.  "The performance and scalability of our Red Brick-based
solutions have exceeded the expectations of our customers."
        ALTA's NETMAP system and solutions provide utility and power for
analysis applications relating to concerns such as asset management, fraud,
trend and pattern analysis and relationship tracking for intelligence
agencies, law enforcement, insurance, retail and other commercial disciplines.
While intelligence and law enforcement agencies historically have been the key
markets for NETMAP, the development of the system is closely followed by other
types of agencies and commercial organizations that are responsible for
managing similar prevention and containment techniques and knowledge discovery
processes.
