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

Text and Dynamic Text


Text components are similar to Label components. They provide much more flexibility than Labels, in that they allow HTML formatting inside of the definition for the text. They also allow for some special tags that will display data from a JavaScript environment. This becomes important if we want to add AJAX or dynamic DOM manipulation to our report. It is even possible to put in images without using the BIRT Image component and anchor tags.

For the following example we will build on to our Hello World report by adding in a list that will be formatted with HTML. The items will be Item 1, Item 2, and Item 3 respectively. Item 1 will be set to bold using HTML, whereas Item 2 and Item 3 will be left alone. For the purpose of this example, you do not need to be familiar with HTML as I will walk you through the steps. A detailed tutorial on HTML is beyond of the scope of this book.
