The data in a database persists for varying periods of time. The data can be transient in nature, or it can persist for longer periods. It typically originates as input data which is initially entered into the database and then becomes persistent data. It can also be output data, which may be displayed in web-based formats or on printed reports. This output data may be derived from the persistent data, rather than being part of the database itself.

Analysis takes two forms:

 a)  Business Analysis-- Includes business process analysis, planning, requirements gathering, conducting surveys, user interaction, and presentation using standard templates and the Rational Rose Unified Modeling Language Tool.

 b)  Data Analysis -- Includes data patterning using graphical methods , statistical data analysis,data mining, multivariate data analysis, the six-sigma and meta-analysis methods.
