Pentaho Architecture, Projects, Tool Set

Pentaho is the open source Business Intelligence leader that founded in 2004. It provides enterprise-class Reporting, Analysis, Dashboards, Data Integration, Data Mining, and Workflow capabilities.

Architecture
The Pentaho BI Suite is different from traditional BI offerings. It is a process-centric, solution-oriented platform with BI components that enable companies to develop complete solutions to BI problems. The core architecture and foundation of the Pentaho BI Suite is the Pentaho BI Platform, which is process-centric because the central controller is a workflow engine.

The Pentaho BI Suite consists of a BI platform, end-user BI capabilities, and the Pentaho Design Studio:
1. The BI platform provides and execution framework and services that include logging, auditing, security, scheduling, ETL, web services, attribute repository and rules engines.
2. The end-user BI capabilities include reporting, analysis, workflow, dashboards, and data mining.
3. The Pentaho Design Studio is a set  of design and administration tools that are integrated into the popular Eclipse environment. These tools allow business analysts or developers to create reports, dashboards, analysis models, business rules, and BI processes.
4. The BI platform and end-user BI capabilities form the Pentaho Server. BI solutions are as designed using the Pentaho Design Studio and deployed to the Pentaho Server. The Pentaho Server is the runtime engine, driven by the workflow engine, which coordinates the execution and communication between all the BI components.
