Good ETL tool
Use Cases and Deployment Scope
IBM DataStage is use as a ETL tool useful to extract information from the source systems (for example SAP ERP), to trasform them defining the correct logics to calculate KPIs and clean data (Data Quality checks). Morever it is used to read manul file from Business Users and to link them into the useful information for the BI tool.
Pros
- Easy to use, you can manage both visual joins and transformation and SQL queries
- Able to read from all source systems, there are all the needed connectors
- It can orchestrate job at different levels and it is easily scalable
Cons
- Many specific parameters are not well documented and therefore are difficult to use
- The debugging option doesn't work well
- datatype management is complex
Likelihood to Recommend
If you want to create a complex environment with many running jobs linked together and manage dependencies it is very strong. If you want to build everything using custom features you loose pushdown advantage, so many times it is better to write directly SQL queries. Variables management can be really powerfull, but also difficult to set up if you are a beginner.
