"Understanding IBM" WebSphere Data Stage from Oracle Perspective
As we know, PeopleSoft made original Equipment Manufacturer Agreement with IBM, for its WebSphere Data stage ETL tool. It has bundles of Offerings with PeopleSoft EPM.
IBM WebSphere Data stage tool uses ETL Jobs for Targeting Specific Data. From people Soft Source Database. It migrates it to OWS, OWE and MDW tables.

IBM WebSphere Data stage is comprised like a Server tool and client Tool, that which discussed by following.
Data loading by using Predefined or User Defined Jobs.
Data Conversion, by using SQL SELECT type statements.
Data Extraction from Data Sources.
Graphical Design tools for designing ETL maps.
Terminology
You should be familiar with IBM WebSphere Data stage Terms.
Administrators
Administrators handle and configure Data stage Project.
Aggregator Stages
Aggregator Stages Compute Totals or other Functions of sets of Information.
Data Elements
Data Elements specifies the type of data in column and how the data modified.
Container Stages
Container Stages Group, reusable stages and certain links in a Job Design.
Package Installer
This tool starts, you to install Packaged Data stage plugins and Jobs.
Hashed File Stage
A hashed File Groups that is one or many Related Files plus a file Directory. Data stage, that designs hashed files. When you operate a Job that designs, hash files.
Hashed files are utilized for storing information from tables. That is with a Remote Database, if needed, for example as lookup table.
Inter-process Stage
An Inter-Process Stage Accepts, you to run server jobs in parallel on symmetric multiprocessing system.
Data Stage Server
We have three main components.
Package Installer.
Data stage Package Installer Installs Packaged jobs and Certain Plug-ins.
Server
Data Stage Server Operates, jobs that load Data, Transform, and it extracts data into warehouse.
Repository
Repository Stores every Information that needed for designing and Running an ETL Job.
Client
IBM Web server Data Stage client Initiates, you to administrate Projects. That is by Editing, Designing, contents and monitoring Jobs.
Data Stage Director
Data stage Designer. .
Data Stage Administrator.
Data Stage Administrator
Designer
Designing, Editing, and Viewing Components. That is like Jobs and Job components.
Designing, viewing Routines, Transforms, table, Definitions, and Elements.
Exporting and Importing Data Stage Components, that is like projects, jobs and job components.
Director
This Director Initiates.
Job statistics.
Log Entries.
Monitoring Jobs.
Running Jobs.
Scheduling Jobs.
Validating Jobs.
Components
Routines.
Shared Containers.
Environmental Parameters.
Hashed Files.
Jobs.
DSX Files.
Environmental Parameters
Environmental Parameters, like User-Defined Values, that show processing variables. In your ETL Jobs, Environmental parameters such as reusable. They Enable you for Defining processing Variables, once Utilize in Many Jobs.
They also Guide Standardized jobs.
With Environmental Parameters and Reusable, Peoplesoft delivers specific Environmental parameters for jobs. That in every phase of Information Movement. A Single Environmental Parameter is not utilized across ETL jobs.
Shared Containers
These containers are reusable job Elements, a shared container usually comprised of Groups of stages and links. This Link is located in Data Stored in Data Stage Repository.
You can utilize Shared containers for making Common Job elements, that available. That is without any common Job components. That Available throughout your Project.
Shared containers are Reusable, you can define them, once and utilize them in any number of your ETL Jobs.
People Soft Delivers Following Shared containers.
Fact Store Max Record ID
Store Max Value Decimal
Store Max Snap Date
Store Max Record ID
Store Max Last UpdDttm
Store Lang Staging List
Routines
Routine is a combination of Instructions, and logics that perform a task within a Job. For Instance the To integer routine converts. The input value to an Integer.
That is Due to Routines and reusable, by that you can utilize any number of ETL Jobs.
Hashed Files
Hash Files, were certain Views of EPM warehouse tables and they contain only a Subset of Data available in warehouse tables.
These Streamlined Versions of warehouse tables. They used to perform Data validation. That is within ETL Job and Pointed Specific Data from Lookup tables.
ETL Jobs
PeopleSoft Delivers predefined ETL Jobs, they use IBM Web sphere Data Stage. ETL jobs is a collection of linked Stages, Information Elements, and Certain Transformations.
That which define, how we have to extract and transform the load time in target Database.
The stages utilized to change or aggregate data and lookup information.
That is more simple ETL job extracts, data from source tables and process. After that, it will write data to point target Warehouse tables.
