This article has multiple issues. On September 19, 2017, Pentaho became part of Hitachi Vantara, a new company that unifies the operations of Pentaho, Hitachi Data Systems and Hitachi Insight Group. Pentaho offers an enterprise and community edition. The enterprise edition contains extra features not found in the community edition. The enterprise edition is obtained through an annual subscription and includes extra support services.
Pentaho’s core offering is frequently enhanced by add-on products, usually in the form of plug-ins, from the company itself and also the broader community of users and enthusiasts. The table below summarizes the most popular products and plug-ins in the Pentaho ecosystem. It includes features for managing security, running reports, displaying dashboards, report bursting, scripted business rules, OLAP analysis and scheduling out of the box. Commercial plug-ins from Pentaho expand out-of-the-box features. Mondrian can be run separately from the Pentaho BI Platform, but is always bundled with the platform itself in both EE and CE versions.
The Pentaho Analyzer plug-in provides a web-based, drag-and-drop OLAP viewer. It allows a user to visually create MDX queries by dragging parts of a previously defined Mondrian OLAP schema onto a canvas, where other activities can take place like filtering, sorting, creating calculated members from other measures, exporting the result table to PDF or MS Excel, and optionally graphing the data. During the steps of creating a data source users also are given a chance to create a data model describing how columns or fields relate to each other creating hierarchies of relationships like Time: Year, Quarters, Months, Weeks and Product Division, Category, Type etc. The resultant model is used by Mondrian and any other plug-in like Analyzer or Saiku to create new queries against the newly created data source. This component is part of what Pentaho introduces as agile BI, which simply means having a way to start from basic data and quickly iterate through steps to discover the proper way to structure, study and present the data. A new addition since 4.
It exposes all of the major functionality of OLAP analysis and running of reports and dashboards that allow greater interaction on a small, touchscreen. Mobile also adds features for bookmarking favorite content for easy access and the concept of opening several pieces of content in tabs. It supports deployment on single node computers as well as on a cloud, or cluster. Hadoop distributions such as Amazon, Cloudera, EMC Greenplum, MapR, and Hortonworks. Pentaho Report Designer is a visual, banded report writer. Features include using subreports, charts and graphs. Community Data Access, scripting, static table definitions and more.
It contains functions for data processing, regression analysis, classification methods, cluster analysis, and visualization. Based on the discovered patterns, users can predict future trends. The metadata editor is used to create business models and act as an abstraction layer from the underlying data sources. XML schema files and the database with the underlying tables described by the schema to generate precalculated, aggregated answers to speed up analysis work and MDX queries executed against Mondrian. This is accomplished by the software examining the hierarchies described in the schema and the measures also defined there and generating SQL which would result in the creation of tables storing those answers away for future use by Mondrian. After using the software to generate these aggregate tables, the original Mondrian XML schema file describing the OLAP cube is modified to reference the precomputed results. The schema created is stored as a regular XML file on disk.
It is not necessary to use the Schema Workbench to create schema, but it is often helpful for beginners and even experts who need go inspect a cube visually and come up to speed with how to maintain or extend it. Design Studio is a modified version of the Eclipse Development Environment with a plug-in designed to understand the components supported by xaction scripts. Developers are starting to use Pentaho Data Integration transformation files to carry out automation and business logic tasks. It is a small leap to imagine PDI transformations will eventually replace xactions entirely.
