　　A complete guide to Pentaho Kettle, the Pentaho Data

lntegration toolset for ETL This practical book is a complete guide

to installing, configuring, and managing Pentaho Kettle. If you’re

a database administrator or developer, you’ll first get up to speed

on Kettle basics and how to apply Kettle to create ETL

soluti***—before progressing to specialized concepts such as

clustering, extensibility, and data vault models. Learn how to

design and build every phase of an ETL solution.

Shows developers and database administrators how to use the

open-source Pentaho Kettle for enterprise-level ETL processes

(Extracting, Transforming, and Loading data) Assumes no prior

knowledge of Kettle or ETL, and brings beginners thoroughly up to

speed at their own pace Explains how to get Kettle soluti*** up and

running, then follows the 34 ETL subsystems model, as created by

the Kimball Group, to explore the entire ETL lifecycle, including

all ***ects of data warehousing with Kettle Goes beyond routine

tasks to explore how to extend Kettle and scale Kettle soluti***

using a distributed “cloud” Get the most out of Pentaho Kettle and

your data warehousing with this detailed guide—from *** single

table data migration to complex multisystem clustered data

integration tasks.

From the Back Cover The ultimate resource on building and

deploying data integration soluti*** with Kettle

Kettle is a scaleable and extensible open source ETL and data

integration tool that lets you extract data from databases, flat

and XML files, web services, ERP systems, and OLAP cubes. It

provides over 120 built-in transformation steps to validate,

cleanse, and conform data, as well as numerous opti*** to load data

into data warehouses and many other targets. Kettle is a

comprehensive, low-cost alternative to traditional data integration

tools like Informatica PowerCenter, IBM InfoSphere DataStage, and

BusinessObjects Data Integrator.

This book explains in detail how to use Kettle to create, test,

and deploy your own ETL and data integration soluti***. You'll

learn to use Kettle's programs to create transformati*** and jobs,

use version control, audit data, and schedule your ETL solution.

Then you'll progress to more advanced concepts such as clustering

and cloud computing, real-time data integration, loading a Data

Vault model, and extending Kettle by building your own plugins. In

addition, you'll find hands-on examples and case studies that show

exactly how to put Kettle's features into practice.

Explore the components of the Kettle ETL toolset

Discover how to install and configure Kettle and connect it to

various data sources and targets
