I always predicted that Open Source BI has to reach critical mass before it becomes a viable alternative for large enterprise BI platforms. All the individual components (a mixture of Open Source BI projects and commercial vendor wrappers around them) are slowly but surely catching up to their bigger closed source BI brothers. Talend and Kettle (a Pentaho led project) offer data integration components like ETL, Mondrian and Palo (SourceForge projects) have OLAP servers, BIRT (an Eclipse project), Actuate, Jaspersoft and Pentaho have impressive reporting components, Infobright innovates with columnar dbms well suited for BI, and productized offerings from consulting companies like European based Engineering Ingegneria Informatica – SpagoBI – offer some Open Source BI component integration.
However, even large closed source BI vendors that acquired multiple BI components over the years still struggle with full, seamless component integration. So what chance do Open Source BI projects and vendors with independent leadership structure and often varying priorities have for integrating highly critical BI components such as metadata, data access layers, GUI, common prompting/sorting/ranking/filtering approaches, drill-throughs from one product to another, etc? Today, close to none. However, a potential consolidation of such products and technologies under one roof can indeed create a highly needed critical mass and give these individual components a chance to grow into large enterprise quality BI solutions.
