BIRT 2.6 Data Analysis and Reporting

By: John Ward

Overview of this book

BIRT is an Eclipse-based open source reporting system for web applications based on Java and Java EE. To address a wide range of reporting needs within a typical application, ranging from operational or enterprise reporting to multi-dimensional online analytical processing (OLAP), you need to know BIRT from head to toe. If you wish to start making reports easily and quickly, and also want to be up-to-date with the latest developments in BIRT, then this book is for you. It will guide you from scratch to develop reports using the Eclipse BIRT project. You will learn how to connect to data, use report items to display and format data, and use scripting to build advanced reports and charts.The book steers you through each step of report setup, to creating, designing, formatting, and deploying reports with data from a wide range of data sources. Its focus is on familiarizing you with the most visible and familiar product built with the BIRT framework – the BIRT Report Designer. It starts by introducing the concepts of business intelligence and open source software, and different installation methods. It will introduce you to the various visual report elements that can be used to design BIRT reports, such as the Palette and Grid components. You will learn the details of the data components of BIRT (the Data Source and the Data Set), different types of source data that BIRT supports such as XML files, flat text files, and databases, and the creation of all of the elements while connecting to Data Sources in reports and Report Projects. By the end of the book, you will be able to enhance the presentation of your report using Charts, Hyperlinks, and Drill Through. You will also be able to take advantage of the scripting capabilities that BIRT has to offer with Expressions and Event Handlers and successfully deploy BIRT reports.The book includes a case study at the end along with a real-world example that runs throughout the book.

Preface

Types of Scripting


In BIRT, there are two different types of scripting—expressions and event handling. Expressions are simple bits of script, usually ranging from 1 to less than 10 lines of code, returning a single value for use in a BIRT report. Event Handling scripts are usually a bit larger than expressions, and are meant to accomplish some sort of task such as retrieve a row from a dataset, manipulate some data before it is sent to output, or handle preparations for rendering. It is recommended that the reader learn more about JavaScript to assist with their report development.

Expressions

Expressions make up a bulk of the scripting used in BIRT. In fact, we have used Expressions multiple times already in this book. Expressions are usually single line statements that return a single result. Tasks such as retrieving a value from a row and outputing it in a data element, retrieving parameter values, and the Highlight expressions used in the last chapter are all examples of Expressions.
