Introduction
DataVista Spectrum™ is an amazingly versatile Java applet that converts very large collections of data into interactive color maps to provide an easy, intuitive way to examine all the available data visually. A powerful equation editing facility enables the creation of new data series that are functions of the existing data. DataVista Spectrum is extremely effective in any environment that requires monitoring and exploring large and dynamic data sets.
Typical applications of DataVista Spectrum include.
  • Risk management
  • Network monitoring
  • E-commerce site management.
  • DataVista Spectrum supports a pluggable data architecture that enables the display of any proprietary data source in addition to JDBC and data stored within its open, XML-based configuration file.
    Features
    Data visualization techniques are applied throughout the DataVista Spectrum interface in order to improve the speed at which data are comprehended and acted upon.
    DataVista Spectrum represents each piece of data as a colored square arranged within a regular grid. A data item is assigned to a row and column based upon user-defined attributes. There is no limit to the number of rows and columns or the size of the underlying database.
    This simple technique of employing colors to represent values enables salient features and patterns of large databases to present themselves much more quickly than similar data represented as tabular data or through common charts and graphs.

    Colors are assigned to data through the use of a configurable gradient. This gradient, along with a visualization of the data distribution, is displayed below the actual data. Advanced users may develop custom gradients and plug them into DataVista Spectrum.

    Operations range from simple addition, subtraction, and multiplication to complex Boolean expressions and conditions. The various built-in functions include trigonometric, logarithmic, rounding and many others.
    DataVista Spectrum 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 situation is particularly relevant in financial, network and web-site monitoring applications. DataVista Spectrum aptly handles data that change over time, continually updating its display and custom expressions to present them in a continuous fashion.
    DataVista Spectrum Benefits
    DataVista Spectrum is able to import and display data of various types from a wide range of sources making it useful in many situations, such as financial research, risk management, real-time network monitoring, market analysis and customer relationship management. For example, a risk management application would partition asset positions into various groupings such as portfolio manager and asset class. Each position could then be assigned a color that is proportional to its contribution to the overall risk of the portfolio. These data then would update over time to reflect current market conditions.
    DataVista Spectrum provides the user with the capability of expanding upon existing data through the creation and modification of custom expressions that are represented and functions of the existing underlying data.
    Expressions may be included at execution time, or created by the user from within this flexible applet. Expressions are created through a flexible, and easy-to-use expression editor interface. Through the use of the mouse, and without any typing, complex equations based upon the underlying data are developed, displayed and later refined. The ability to add and modify custom expressions greatly enhances the flexibility and power of DataVista Spectrum to enable better decisions based upon your data.
    Incorporating DataVista Spectrum into Your Architecture
    DataVista Spectrum is configured through a very flexible XML-based configuration mechanism. All aspects of DataVista Spectrum's appearance and functionality are configurable ranging from data access to chart presentation to exception handling. The same XML that configures the applet may be employed to configure the servlet, further reducing the effort expended in deploying a unified client-server solution.
    DataVista Spectrum may obtain its data from any of several sources, thereby providing seamless integration 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.
