ER Models for Optimal Building of Reports

Reports, in general, are a form of representing data in such way that user gets the information he needs. They can be built in various ways, from the simpliest (“ select from” ) to the most complex ones (results derived from different sources/tables with complex formulas applied). Rules of calculations could be written as a program hard code or built in the database. This paper will introduce two types of reports, defined in the DB structure. The main goal is to manage calculations in optimal way, keeping maintenance of reports simple and as smooth as possible.
