☛ Makes reporting, monitoring, placing customer information across the enterprise flexible and
☛ Data usage is efficient.
☛ Cost Effective.
☛ Risk adjusted profitability management as it allows accurate data extraction.
☛ Allows timely and reliable reporting, as data quality is the prime technology for business challenges.
Data profiling is the process of assessing and understanding the content, quality, and structure of enterprise data. It is an essential step in reconciling semantic differences in common business vocabulary such as customer, address, and product that varies among applications, and which, if unaddressed, results in contradictory information across the enterprise.
