  • Interactive web based “ad hoc” report development and data exploration (AJAX) against any data source.
  • End user query through the browser, based on “data domains” which include data level security. A web based domain designer is provided. JDBC only at this stage.
  • In-memory data access and calculation engine to support ad hoc. Includes server management like query governing.
  • Dashboards made up of multiple reports, images and external web content can be designed through the browser (AJAX).
  • User profile based data level security for OLAP analysis, beyond simple roles.
  • Performance tuning and management tools.
  • Multi-tenant enabled to support “business intelligence as a service” for SaaS vendors and organizations that share JasperReports Server across customers or departments.
  • Complete translations of the JasperReports Server user interface and documentation for English, French, German, Spanish and Japanese (Chinese coming soon)
  • Out of the box support to allow JasperReports Server to run in a large variety of application servers and databases for the repository. JasperReports Server Community Edition and Professional Edition can connect to a wide variety of databases for reporting and analysis through JDBC.
7.What is the use of Jasper Report?
Jasper Reports is used to generate the reports from the Database. A powerful report-generating tool that has the ability to deliver rich content onto the screen, to the printer or into PDF, HTML, XLS, CSV and XML files. Its main use is to help creating page oriented, ready to print documents in a simple flexible manner.
8. What is iReport Designer?
There are several ways to add reporting capabilities to an application. For many web developers, to create a report just means to create a web page, which produces good results on screen but poor results when printed to paper. And to create a report in PDF means write more code tons of code, making the reports hard to maintain and long to write. When working with other technologies the problem does not change very much. For example, Java provides an extensive API for printing, but there is still a lot of work to write specific code for each document format.The answer to this problem is to use a reporting library. JasperReports Library is the world’s most popular open source Java reporting library, and iReport Designer is a visual report designer for JasperReports. The library is a report engine that can be integrated in your open or commercial application to generate the reports designed with iReport Designer, display them on screen or export them in a final format like PDF, OpenOffice, DOCX and many others. Alternatively, you can stream the result through a web application or send the final document directly to a printer. JasperReports is in some way the core of iReport Designer.JasperReports is extremely easy to integrate in an Java application, but if you need an environment to use the reports without having to write a custom application, you may consider using JasperReports Server.JasperServer provides a web based interface to manage, schedule, and run the reports; a repository to store all the report resources like images, fonts, data sources and much more; a security service to decide who can execute which report; and a web services API to execute the reports from external applications (so you can generate reports from any kind of environment, like PHP or .NET).In the big picture, iReport Designer allows you to design reports, JasperReports allows to execute them and generate output in a Java application, and JasperServer allows both end users and external applications to access, view, and publish your reports securely. JasperServer also makes reports interactive by adding drill down and drill up capabilities to your documents.
9.What is Jaspersoft ETL?
Jaspersoft ETL is a complete and ready-to-run ETL job designer with an extensive set of data integration capabilities. It consistently and accurately extracts and transforms data from multiple systems and loads it into data stores optimized for reporting and analysis such as star or snowflake schema data marts and warehouses. And it easily keeps pace with the performance of other leading ETL tools. With JasperETL, database architects and operational data store administrators can:

  • Use the business modeler to access a non-technical view of the information workflow.
  • Display and edit the ETL process with Job Designer, a graphical editing tool.
  • Define complex mappings and transformations with Transformation Mapper and other transformation components.
  • Generate portable Perl or Java code that can be executed on any machine.
  • Track ETL statistics from start to finish with real-time debugging.
  • Allow simultaneous output from and input to multiple sources including flat files, XML files, databases, web services, POP and FTP servers with hundreds of available connectors.
  • Configure heterogeneous data sources and complex file formats including positional, delimited, CSV, RegExp, XML, and LDIF with metadata wizards.
