Another BI tool worth checking out is one called A Reporting Tool(ART)[0]. ART has been around for well over 10 years. Not the classiest looking piece of software but it is packed with features BI people will appreciate. For starters it integrates with JasperReports. This means you can design reports for printing using Jasper designer. It integrates quite a few Java libraries allowing you to create reports using Excel and PowerPoint. LDAP integration is built in and it has a nifty scheduler allowing you to publish reports to FTP locations. It really is a nifty tool. Like I said it doesn't compete with the modern tools in terms of looks but it packs a whole lot of features. You configure your own JDBC driver and there is a JDBC driver for most databases and data stores.
