projects involve analyzing unstructured data.
- Exploratory projects involve analyzing large
datasets, while confirmatory projects involve
analyzing smaller datasets.
- Exploratory projects involve analyzing data
from a single source, while confirmatory pro-
jects involve integrating data from multiple
sources.
