4 major components:ExtractingGathering raw data from source systems and storing it in ETL staging environmentData profilingIdentifying data that changed since last loadTransforming- Cleaning and ConformingProcessing data to improve its quality, format it, merge from multiple sources, enforce conformed dimensionsData cleansingRecording error eventsAudit dimensionsCreating and maintaining conformed dimensions and facts

Data filteringIs not null, greater than, less than, includesField manipulationTrimming, padding, upper and lowercase conversionData calculations+ - X / , average, absolute value, arctangent, natural logarithmDate manipulationFirst day of month, Last day of month, add months, week of year, day of yearData type conversionString to number, number to string, date to numberMerging fields & splitting fieldsLooking up dateLook up in a database, in a text file, an excel sheet,


LoadingLoading data into data warehouse tablesManaging hierarchies in dimensionsManaging special dimensions such as date and time, junk, mini, shrunken, small static, and user-maintained dimensionsFact table loadingBuilding and maintaining bridge dimension tablesHandling late arriving dataManagement of conformed dimensionsAdministration of fact tablesBuilding aggregationsBuilding OLAP cubesTransferring DW data to other environment for specific purposes


Complexity and significant operational problems.Exceeds the designers expectationsData Profilingof a source.Data warehouses typically grow asynchronously.Establishing thescalability of an ETL system across the lifetime .

PanA program to execute transformations designed by Spoon in XML or database repository. Transformations are scheduled in batch mode to be run automatically at regular intervals CarteSimple web server to execute transformations and jobs remotely.Accept an XML (small servlet) that contains transformation to execute and the execution configuration. Allows to remotely monitor, start and stop the transformations and jobs Server running in Carte is a Slave Server


SpoonGUI that allows you to design transformations and jobs that can be run with the Kettle tools Pan and Kitchen Transformations and Jobs can describe themselves using an XML file or can be put in a Kettle database repository.Spoon is available as executable script and batch file to make use of tool in heterogeneous environment.Latest version of Spoon is 3.2 beta version. KitchenExecute jobs designed by Spoon in XML or database repository


Create Shortcut with spoon.ico pointing to bat fileWorks on most of OS InstallingEnsure JRE 1.5 is installed.Unzip the binary distribution in any folderLaunching spoon.bat in windows platformspoon.sh in Unix like platform Supported platformMicrosoft Windows including VistaLinux GTK: on i386 and x86_64 processors Apple's OSX: works both on PowerPC and Intel machines Solaris: using a Motif interface AIX, HP-UX, FreeBSD 04/17/14MaxQDPro: Kettle- ETL Tool*

Latest JDBC 3.0JDBC -Database connectivity Java tool.Comes in four different typesType1: JDBC-ODBC BridgeType 2 : Native API partial Java driverType 3 : Middleware Java DriversType 4: Direct to DB Java DriversMicrosoft Based DB like MS Access rely on Type 1driversOracle, Mysql can be connected with other types. But traditionally used is the Type 4 driver.JDBC can also operate in Distributed environment.04/17/14MaxQDPro: Kettle- ETL Tool*

Repository Connection establishmentAuto loginBy setting manually KETTLE_REPOSITORY, KETTLE_USER and KETTLE_PASSWORD environmental variables.LoginBy default PDI provides login username and password ad admin.It strictly advised to change default password to avoid any security vulnerablity.04/17/14MaxQDPro: Kettle- ETL Tool*

Transformation Value: Values are part of a row and can contain any type of dataRow: a row exists of 0 or more valuesOutput stream: an output stream is a stack of rows that leaves a step.Input stream: an input stream is a stack of rows that enters a step.Hop: A hop is a graphical representation of one or more data streams between 2 steps. Note: A note is a piece of information that can be added to a transformation04/17/14MaxQDPro: Kettle- ETL Tool*Engine capable of performing a multitude of functions such as reading, manipulating and writing data to and from various data sources.

JobsJob Entry: A job entry is one part of a job and performs a certainHop: A hop is a graphical representation of one or more data streams between 2 steps Note: a note is a piece of information that can be added to a job04/17/14MaxQDPro: Kettle- ETL Tool*A way of calling transformations and controlling the sequence of their execution. Usually jobs are scheduled in batch mode to be run automatically at regular intervals.

Besides the execution order, it specifies the condition for next job entry

Unconditional - next job entry will be executed regardless of the result of the originating job entry.

Follow when result is true - next job entry will only be executed when the result of the originating job entry is true,

Follow when result is false - next job entry will only be executed when the result of the originating job entry was false04/17/14*MaxQDPro: Kettle- ETL Tool
