About Data Preparation
With Data Preparation, you can create datasets from various sources: data files, databases, IBM Cognos packages and cubes. You can refine the existing data by filtering, changing the aggregation, creating calculations, and by joining several data sources.
You can also add connections to remote artificial intelligence (AI) or machine learning (ML) servers, and create script calculations for your datasets using R or Python.
After you create a dataset, you can share it with other users, or you can use it outside the Platform, in other BI tools.
