Graphical design tools for designing ETL maps called jobs. Data extraction from a variety of data sources. Data conversion using predefined or user-defined transformations and functions. Data loading using predefined or user-defined jobs. Administrators maintain and configure DataStage projects. Aggregator Stages. Aggregator stages compute totals or other functions of sets of data.
Data Elements. Data elements specify the type of data in a column and how the data is converted. Container Stages. Container stages group reusable stages and links in a job design. DataStage Package Installer. This tool enables you to install packaged DataStage jobs and plug-ins. Hashed File. A hashed file groups one or more related files plus a file dictionary. Hashed files are useful for storing data from tables from a remote database if they are queried frequently, for instance, as a lookup table.
Hashed File Stage. A hashed file stage extracts data from or loads data into a database containing hashed files. You can also use hashed file stages as lookups. PeopleSoft ETL jobs use hashed files as lookups. Inter-process Stage. An inter-process stage allows you to run server jobs in parallel on a symmetric multiprocessing system.
Plug-in Stages. Plug-in stages perform processing that is not supported by the standard server job stage. Sequential File Stage. A sequential file stage extracts data from or writes data to a text file. Transform Function. A transform function takes one value and computes another value from it. Transformer Stages. Transformer stages handle data, perform any conversions required, and pass data to another stage.
A job is a collection of linked stages, data elements, and transforms that define how to extract, cleanse, transform, integrate, and load data into a target database. Jobs can either be server or mainframe jobs. Job Sequence.
Job sequence invokes and runs other jobs. Join Stages. Join stages are mainframe processing stages or parallel job active stages that join two input sources. Metadata is data about data; for example, a table definition describing columns in which data is structured. This diagram illustrates the DataStage Server. The Repository stores all the information required for building and running an ETL job.
The DataStage Server runs jobs that extract, transform, and load data into the warehouse. The DataStage Package Installer installs packaged jobs and plug-ins. This diagram illustrates the tasks that can be performed by the DataStage Administrator. Create, edit, and view objects in the metadata repository. Create, edit, and view data elements, table definitions, transforms, and routines.
Import and export DataStage components, such as projects, jobs, and job components. Create ETL jobs, job sequences, containers, routines, and job templates. See DataStage Designer Overview. See DataStage Director Overview. Some of these components include stages, jobs, and parameters.
Only the following key DataStage components are discussed in this topic:. ETL Jobs are a collection of linked stages, data elements, and transformations that define how to extract, transform, and load data into a target database. Stages are used to transform or aggregate data, and lookup information. More simply, ETL jobs extract data from source tables, process it, then write the data to target warehouse tables.
PeopleSoft deliver five types of jobs that perform different functions depending on the data being processed, and the warehouse layer in which it is being processed:. Jobs in this category extract data from your PeopleSoft transaction system and populate target warehouse tables in the OWS layer of the warehouse. Jobs in this category extract data from your transaction system and populate target dimension and fact tables in the MDW layer of the warehouse.
The Online Marketing data mart is the only product to use this type of job. Many of the jobs aggregate your transaction data for the target F00 tables. The jobs also perform lookup validations for the target DIM and FACT tables to ensure there are no information gaps and maintain referential integrity.
All job types identified in the table are incremental load jobs. Incremental load jobs identify and extract only new or changed source records and bring it into target warehouse tables. PeopleSoft use standard naming conventions for all ETL jobs; this ensures consistency across different projects. Hash files are views of specific EPM warehouse tables and contain only a subset of the data available in the warehouse tables.
These streamlined versions of warehouse tables are used to perform data validation lookups within an ETL job and select specific data from lookup tables such as sourceID fields in dimensions.
In the validation lookup process the smaller hash file is accessed, rather than the base warehouse table, improving performance. The following diagram provides an example of a hash file lookup in a job. A detailed view of the hashed file stage reveals the fields including keys the lookup uses to validate Institution records. Because hash files are vital to the lookup process, jobs cannot function properly until all hash files are created and populated with data.
Before you run any job that requires a hash file, you must first run all jobs that create and load the hash files—also called initial hash file load jobs. After hash files are created and populated by the initial hash file load jobs, they are updated on a regular basis by the delivered sequencer jobs.
Hash files are updated in the same job as its related target warehouse table is updated. In other words, both the target warehouse table and the related hash file are updated in the same sequencer job. The successful load of the target warehouse table in the job triggers the load of the related hash file. The following diagram provides an example of the this process. Environmental parameters are user-defined values that represent processing variables in your ETL jobs.
Environmental parameters are reusable so they enable you to define a processing variable once and use it in several jobs. They also help standardize your jobs. Though environmental parameters are reusable, PeopleSoft delivers specific environmental parameters for jobs related to each phase of data movement such as the OWS to MDW jobs.
Therefore, a single environmental parameter is not used across all ETL jobs, rather a subset of variables are used depending on the specific functionality of the job. See Environmental Parameters Information. Shared containers are reusable job elements. A shared container is usually comprised of groups of stages and links, and is stored in the DataStage repository. You can use shared containers to make common job components available throughout your project. Because shared containers are reusable you can define them once and use them in any number of your ETL jobs.
PeopleSoft delivers the following shared containers:. Routines are a set of instructions, or logic, that perform a task within a job. For example, the ToInteger routine converts the input value to an integer. Because routines are reusable you can use them in any number of your ETL jobs.
See Routine Descriptions. The following table lists the IBM documentation and the information provided.

Datastage is an ETL tool which extracts data, transform and load data from source to the target. The data sources might include sequential files, indexed files, relational databases, external data sources, archives, enterprise applications, etc. DataStage facilitates business analysis by providing quality data to help in gaining business intelligence. Datastage is used in a large organization as an interface between different systems. It takes care of extraction, translation, and loading of data from source to the target destination. It was first launched by VMark in mid's. It describes the flow of data from a data source to a data target.

The aim of the exercise is to get you familiar with the Designer client, so that you are confident to design more complex jobs. There is also a dedicated tutorial for parallel jobs, which goes into more depth about designing parallel jobs. This exercise walks you through the creation of a simple job. In this exercise you design and run a simple parallel job that reads data from a text file, changes the format of the dates that the file contains, and writes the transformed data back to another text file. The source text file contains data from a wholesaler who deals in car parts.
