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.
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.
