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

The current state of the BI market


The current state of the BI market is similar to the state of any technology field. It can change at the drop of the hat. At the time of this writing, you can divide the major players in two categories—commercial offerings and open source offerings. Each route has its own benefits and drawbacks. Certain familiar names are associated with the commercial offerings, for example Actuate and Business Objects offers various tools aimed at different levels of business. Some of these tools are large enterprise reporting platforms that have the ability to process, analyze, and reformat large quantities of data. With commercial offerings, you get product support and years of experience. With the big guys, you often get professional services too such as consultation in developing your reports for a fee. One of the drawbacks of commercial offerings is the large price associated with them, both in terms of purchasing and running them. Some companies, in addition to the initial cost which, at times, can run up to thousands of dollars, also charge for yearly maintenance, upgrade fees, and have an additional cost of ownership that may be typically overlooked. There is also the cost of licensing. If you are building a large scale custom application, are you allowed to integrate these products into your application? If yes, then are there any restrictions? And finally, the years of engineering behind a product may leverage an obsolete methodology. Perhaps the technology behind these products is no longer viable or powerful enough to handle the demands of a growing enterprise.

Then you have your open source offerings. Currently there are three big names in the open source reporting realm—JasperReport, Pentaho, and BIRT. Two of these projects, JasperReports and BIRT, are run by commercial companies who make money doing professional services for these offerings to small scale, private projects. Again, there are a number of pros and cons associated with open source solutions. With open source, you have full access to the source code of the platform you choose. This allows you to add in functionality, embed it with in your existing applications, and actively participate in a development community that is often times very large and worldwide. There is little initial cost to open source in terms of purchasing because any open source tool is available free of charge. There are a few disadvantages too. There is typically a cost associated with finding individuals knowledgeable in open source. Sometimes open source is not very user friendly. And finally, there is often little to no support for open source products. This is not the case with large open source projects. However, with the large active development communities associated with open source projects such as Linux, Eclipse, and Mozilla/Firefox, answers to your support-related queries are only an internet search away.
