02: Overview of Datastage Designer Client

After creating your project, it is time to know about designer client to start developing ETL.


There are different sections in Designer screen. At the top, you see menubar (1) and toolbar (2) (that I will explain each tool when we go deep into developing process).

(3) Repository: DS suggests a standard repository structure to organize repository objects. You can add new folders and organize them together with the existing ones.

(4) Palette: Palette keeps the building elements (called stages in parallel and server jobs, called activities in sequence jobs) to develop ETL jobs. Stages are orginized in different sections based on their funcltionalities.

(5) Log: to make your life easier during development, you can show log view in designer client. If it does not appear on your screen, you can activate from view menu.

(6) Canvas: place holder to design our jobs. You can drag and drop any stage in palette to canvas and link them to have end-to-end job.

The first DS Job :)


Basically an ETL job requires three stages.
1- DB connector/enterprise/file stage to connect to data source and extract data
2- Transformer stage to make all necessary transformations and map to output columns
3- DB connector/enterprise/file stage to connect target and load data

Depending on your needs you can use further processing stages like lookup, copy, filter etc.
