point of activity as possible.

diverse data sources to widen the competitive differentiation gap
Types of bad data
*Duplicate data: Two or more identical records
*Conflicting data: The same records with differing attributes
*Incomplete data: Missing attributes
*Invalid data: Attributes not conforming to standardization
*Unsynchronized data: Data not appropriately shared between two systems
