About Yellowfin

Yellowfin stores the all application configuration data such as authorisation and authentication permissions, logical views of the data, report definitions, field definitions, execution statistics and information about this data (metadata) in the Yellowfin database.

Users and administrators define these data items via a Browser Interface. Yellowfin then converts these various data components into an SQL query at runtime and generates the required report and delivers it to the user interface. From there users can choose the format in which is stored eg. Spreadsheet, PDF, html report etc.

Architecture Overview
