This is a configuration plan for Oracle BI Cloud Connector (BICC).
It is not a single executable SQL script. Instead, it details which PVOs
and columns to select within the BICC user interface to generate the raw
data files needed for the Hire to Retire event log.
The post-processing script mentioned in the 'howto' section will use these
files to construct the final event log by mapping columns and assigning
the correct ActivityName.
