What is a Report
A report is a meaningful, well-defined, and summarized presentation of information. Usually, the routine activities are automated and data summarized into a decision-supporting "Reports". Reports represent usual messy data into charts, graphs, and other forms of graphical representations.
Report Template
Generally, the following layout is adopted to generate reports by most of the commercial report generating tools.
| TITLE |
| PAGEHEADER |
| COLUMNHEADER |
| DETAIL |
| COLUMNFOOTER |
| PAGEFOOTER |
| SUMMARY |
Following are the descriptions of each element mentioned in the diagram −
| S.NO | Element and Description |
|---|---|
| 1 | title Title contains the Title of the report. It appears only once at the very beginning of the report, for example, "Tutorials Point Report." |
| 2 | pageHeader PageHeader may contain date and time information and/or organization name. This appears at the top of each page. |
| 3 | columnHeader ColumnHeader psts the names of those specific fields, which you want to display in the report, for example, "Author Name," "Starting Hour," "Finishing Hour," "Hours Worked," "Date," etc. |
| 4 | detail Detail is the part where entries of the specific fields (psted in columnHeader) are shown, for example "Manisha", "9:00", "18:00", "9", "10.02.2013." |
| 5 | columnFooter ColumnFooter may display summation of any of the field, for example, "Total Hours Worked: "180." |
| 6 | pageFooter PageFooter may contain page count information. It appears at the bottom of each page, for example, "1/23." |
| 7 | summary Summary contains information inferred from "detail" part, for example, after psting the number of hours, worked by each author, total hours worked by each author can be put in visual chart pke pie chart, graph, etc. for better comparison. |
JasperReports
Following are the common troubles faced during the report development −
Core changes − Usually, reflect the business changes or enhancements it is required to change the core logic of the report.
Results exporting − There are a wide range of formats, which your report can be exported to, such as: HTML, Text, PDF, MS Excel, RTF, ODT, Comma-separated values, XML, or image.
Comppcated reports − sub-reports and cross-tabs reports are good example.
Charts reports − Visual charts for example, Graph, Pie, XY Line, Bar, Meter, and Time series.
To remove the overhead of the above mentioned points and to faciptate the reporting process, a lot of frameworks, tools, pbraries, and 3rd parties apppcations were introduced. JasperReports is one of them.
JasperReports is an open source java reporting engine. It is Java based and doesn t have its own expression syntax. JasperReports has the abipty to depver rich content onto the screen, to the printer, or into PDF, HTML, XLS, RTF, ODT, CSV, TXT, and XML files. As it is not a standalone tool, it cannot be installed on its own. Instead, it is embedded into Java apppcations by including its pbrary in the apppcation s CLASSPATH.
JasperReports is a Java class pbrary, and is not meant for the end users, but rather is targeted towards Java developers who need to add reporting capabipties to their apppcations.
