What is Oracle DataStage?
The DataStage Designer is the primary interface to the metadata repository and provides a graphical user interface that enables you to view, edit, and assemble DataStage objects from the repository needed to create an ETL job. Create, edit, and view data elements, table definitions, transforms, and routines.
What is repository in DataStage?
The metadata repository is a shared component that stores design-time, runtime, glossary, and other metadata for product modules in the InfoSphere Information Server suite.
What is DataStage version?
IBM InfoSphere DataStage is an ETL tool and part of the IBM Information Platforms Solutions suite and IBM InfoSphere. It uses a graphical notation to construct data integration solutions and is available in various versions such as the Server Edition, the Enterprise Edition, and the MVS Edition.
What is IBM DataStage used for?
IBM® InfoSphere® DataStage® is a data integration tool for designing, developing, and running jobs that move and transform data.
What language is DataStage written in?
At the lowest levels the DataStage server engine is largely written in C. Once upon a time there was some FORTRAN and PL/I in there too, but I believe that’s no longer the case. Only the “public” levels are written in DataStage BASIC.
What is sequencer in DataStage?
You use the Sequencer stage to synchronize the control flow of multiple activities in a job sequence. This stage can have multiple input triggers and multiple output triggers. The Sequencer stage contains a General page and a Sequencer page. All of the inputs must be TRUE to trigger any of the sequencer activities.
What are the triggers available in sequencer activity?
An unconditional trigger runs the target activity once the source activity completes, regardless of what other triggers are run from the same activity….Trigger types in Sequencer Job.
| Conditional trigger | Action |
|---|---|
| Failed | Runs the target activity if the source activity fails |
| ReturnValue | Returns a routine or command when the activity runs |
When to use the ODBC stage in DataStage?
ODBC stages are used to allow Datastage to connect to any data source that represents the Open Database Connectivity API (ODBC) standard. ODBC stages are mainly used to extract or load the data.
How is DataStage used in a large organization?
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-90’s. With IBM acquiring DataStage in 2005, it was renamed to IBM WebSphere DataStage and later to IBM InfoSphere.
How are data connection objects used in DataStage?
In DataStage, you use data connection objects with related connector stages to quickly define a connection to a data source in a job design. Step 1) STAGEDB contains both the Apply control tables that DataStage uses to synchronize its data extraction and the CCD tables from which the data is extracted.
How are jobs created in InfoSphere DataStage application?
A graphical design interface is used to create InfoSphere DataStage applications (known as jobs). Each job determines the data sources, the required transformations, and the destination of the data. Jobs are compiled to create parallel job flows and reusable components.
