TIBCO Jaspersoft

This software is one of the best choices to create reports if you are a Java developer. All you need to know about is Java and SQL for the queries. It integrates with many databases, and I personally have used it with PostgreSQL and it works well. The reports you create from scratch are fully customizable, and can include the elements you need: labels, tables, images, ... I like a lot the subreport element, as it allows to create even more complex / nested reports, in which you usually follow a master-detail model.
In addition, you can use the Java libraries to integrate Jasper reports into your Java application, either Desktop or Web, this will enable

Some features or properties are not too intuitive, which is understandable if we think this is a tool for developers. Even though, it would be nice to have a more intuitive GUI.

* Easy to use
* Flexible scenarios for report grouping
* No cost level available for simple deployment and use
* JasperServer has ability to automate delivery of reports.

* Hard to find support forums (as a community/free user)
* Custom data connectors present a challenge I haven't overcome for automated delivery (SQL reports are easy)

This software is very customizable in terms of the output formats. Scheduled report delivery is very easy to accomplish on their reporting server. It also has the ability to create HTML 5 charts.

The design interface for report creation is atrocious. Very clunky, not intuitive, and dated especially when compared to other tools available (MS Power BI, Tableau, etc.). It is maddeningly picky when it comes to formatting. Reports will function well on in Jaspersoft and not function on a server. The error output is cryptic and requires decoding. Exported reports will look excellent in one format and awful in another. Ineffective documentation from Tibco makes learning the software a challenge if you are not an explorer. Drillable datasets are impossible.
