The Business Intelligence and Reporting Tools (BIRT) program Eclipse is an open source program based on the popular Eclipse IDE and is used to build and deploy reports in a Java/J2EE environment. Some of the important downloads available with the program:

The BIRT program was first released in the summer of 2005 and has received more than one million downloads since its launch. For more information about the BIRT project see http://www.eclipse.org/birt, including an introduction, tutorials, downloads, and usage examples BIRT.

Modifying A Saved Report

We will begin by first describing the BIRT Designer, which is used to build display plans, and finish by discussing the BIRT Viewer example, which is used to design plans and generate reports. show completed.

At the center of BIRT is the presentation designer, which is a set of Eclipse plug-ins that create a presentation designer that provides drag-and-drop capabilities to quickly design presentations. Presentation plans are created and stored in an XML format.

This Eclipse feature contains multiple Eclipse Views that provide functionality for creating a report. These ideas are presented below.

The Editor is used to build the report and acts as a canvas for organizing and linking the reports. Within this View, there are pages for Layout, Master Page, Script, XML Source, and Preview.

Before building a report, it is necessary to set up the data sources. To facilitate this task, BIRT provides the Data Explorer View.

This Eclipse experience allows you to add data sources and data sets to the presentation design. Essentially, a data source is the only connection. The database can be thought of as a query executed and specific columns to be returned.

BIRT provides drivers for JDBC, XML, flat file, and scripted data sources. With the release of BIRT 2.2, BIRT also provides a Web data source and an improved flat file manager that now supports CSV, TSV, SSV, and PSV file formats.

BIRT also provides a special data set called Joint Data Set that allows to combine existing data sets using internal and external joins. This feature is very useful when combining data sets from different data sources. In addition, BIRT data sources now support the ability to link and integrate locally maintained contact profiles to allow sharing of relevant evidence.

Data Visualization is also used to integrate display units and data boxes. Display parameters are the parameters that are displayed to the end user of the display and are often used to customize the display for a particular user. For example, report parameters can be attached to data set parameters to modify a query, used in a BIRT JavaScript statement to change the appearance and visibility of a report, or used to within a display event to customize the view based on the selected output mode. .

Display units can be static or dynamic. Static parameters are parameters that allow the user to select from a pre-selected set or enter a desired value, for example, into a text box. Comparable parameters are parameters that can be mapped to data in a BIRT data set. For example, a user can select a customer from a list of customers provided by a data set.

Additionally, BIRT supports cascading parameters that allow list/combo boxes to be displayed with each option list being replaced by pre-selected values. For example, a cascaded section can display a list of customers in the first list box and orders for a given customer in a second list box.

With BIRT 2.2, dynamic parameters support the use of Java Script expressions for the parameter’s display text and value. This improvement allows the part list to be displayed to the end user in a more efficient manner. For example, when developing an order-specific report, you may want to display a dynamic comparison list of all orders. The message will allow you to add a customer name for each order.

The Data Explorer View allows you to create data cubes. This is a new feature for BIRT 2.2 and is used with the new crosstab indicator. BIRT data cubes are large blocks, containing one or more BIRT data, built using the new Cross Tab Cube Builder. See Palette View for more details.

In addition to the above features, BIRT provides two new types of programs that allow Java developers to create new data sources. These data sources are based on the Open Data Access (ODA) framework provided by the Eclipse Data Tools Platform (DTP) project. The ODA Designer Plug-in Project is used to build the GUI, which is called when the display developer uses your driver. The ODA Runtime Driver Plug-in Project is used to develop the runtime part of your driver. This plug-in is usually installed in a runtime environment and is responsible for making calls to the data source and returning the results.

The BIRT Palette View is used to add display elements to the display canvas. The View Palette contains indicators used to display data collected in the View Explorer. To use a display, simply drag it from the View Palette to the Editor. All BIRT reports support properties that can be set in the View Editor View and defined by the BIRT Report Object Model (ROM).

The Library Explorer View provides drag-and-drop functionality from the libraries available in the current display. Libraries in BIRT effectively represent XML snippets that can be used by other reports. These libraries are referenced from the reports that use them, meaning that changes to the library are visible to all reports that use the library. A good example is using a presentation file to store the company logo. If the company’s logo changes, the database must be updated, not the reports pointing to it. The libraries are linked to the library that can be configured in the developer for design time and in the web.xml of the Web Viewer for run time.

The View Editor View is used to set values ​​for the displays added to the display. The material presented will be decided by the selected witness in the Reviewer. The Properties window displays general settings, such as style, width, and font information. In addition, most of the indicators support the information property that can hide the information dynamically. Located on the right side of the Properties page, this view displays the Sorting, Groups, Map, Highlights, and Filters tabs.

While most of these functions are self-explanatory, the mapping class allows dynamic conditions to be built (using the Expression Builder) to dynamically change the expression value of an expression. For example, if your month row number is “1”, you might want to display “January”.

The Highlights page uses criteria to apply different attributes, such as showing low sales numbers in red. Most of these functions allow conditions or keys to be placed on an object. One condition can change the font color, and another condition can change the font size. One type key can list the results alphabetically, while another type key puts “Jones” at the top of the list.

Additionally, with BIRT 2.2, when requesting values, the report developer can specify an attribute instead of manually setting the values.

The Outline View shows a graphical hierarchy of the display structure and shows the display in the box connection. Presentations can be selected directly in the outline view and is very helpful if you have complex presentation plans. In addition to BIRT 2.2, this information can be used to connect or link to external methods and view reports that implement script event handlers.

Importing a style sheet copies the style’s values ​​into the XML document. Using an external style sheet allows you to link to a style sheet found in the BIRT database.

BIRT 2.2 introduces two new concepts for examples. One view shows sample reports and the other shows sample documents and provides Java code to create the chart. This information is used when using the graph engine in a Java application.

Once report development is complete, reports can be deployed using the BIRT example Web Viewer. The viewer has been improved for BIRT 2.2 and is an AJAX-based J2EE document that demonstrates how to use the BIRT engine to create and render display information.

The Web Viewer can be used for publishing and sharing reports, and also supports related features such as table of contents, export of report information in different formats. , client and server page printing, and pagination display. These features are accessed using the Viewer control and toolbars. An example of using the Viewer is shown below.

The Viewer toolbar contains options for displaying a table of contents, rerunning the report, importing data, moving the report to another format, and client-side and server-side printing. A table of contents is created
