Introduction
DataVista Screener™ supports
a pluggable data architecture, enabling the
display of any proprietary data source in addition
to JDBC and data stored within its open, XML-based
configuration file.
Features
DataVista Screener
employs the power of approximate reasoning
and visualization to provide a simple
and powerful interface for the ranking
of data according to a collection of
user-configurable rules.
Each
rule specifies an ideal range for a
given variable,
data objects are ranked according to
how well they fit within this range.
Several rules may be combined together
using the standard boolean operations
of "and" and "or" to
create a powerful capability for ranking
and filtering data.
Each rule has an associated "certainty" setting
capability that indicates the degree
to which a value may reside outside of
the ideal range and still receive a partial
ranking. Rules with a high certainty
are not as accepting of marginal values
as those with a low certainty. For example,
if the rule is "price between 30
and 50," a high certainty would
not rank data valued at 25 whereas a
low certainty would admit such values.
The degree to which
the data matches your configured
rules is indicated visually through a colored
box. This box is green for objects
that precisely match the rules; it
is red for those that do not match
the rules. The colors vary continuously
between green and red corresponding
to the varying degrees to which the
objects match the rules.
Rules are
editable through an intuitive interface that enables
the rapid specification of rule parameters.
Visualization techniques are employed
to provide a rapid understanding of the
overall distribution of your data.
Dynamic Data
DataVista Screener also provides a powerful framework for monitoring dynamic
data sources. The Internet has significantly increased the necessity for quick
reactions to rapidly changing conditions. This is particularly the case in
financial, network and web site monitoring applications. DataVista Screener
aptly handles data that change over time, continually applying the rules to
highly salient conditions.
Data Access
DataVista
Screener may obtain its data from one of three sources,
ensuring
that it will seamlessly integrate into most
enterprise architectures. The first source
is an open, XML-based format, compatible
with many of the emerging XML-aware applications.
Secondly, data may be imported from any JDBC-compliant
data source (which includes all ODBC data
sources through a JDBC-ODBC bridge). Lastly,
a pluggable architecture allows any Java
object implementing a simple, well-documented
interface to serve as a data source.
