iReport
Report generation is process of fetching data from database and displaying those data to Users. It may be with some period of time like weekly, monthly.etc.. Report generation is used to view historical data.
iReport is the free, open source report designer for Jasper Reports, available for all major operating systems under the GNU General Public License. Use iReport to create very complex layouts containing charts, images, sub reports, crosstabs and much more. Access your data through JDBC, Table Models, JavaBeans, XML, Hibernate, CSV, and custom sources. Then publish your reports as PDF, RTF, XML, XLS, CSV, HTML, XHTML, text, DOCX, or Open Office.
