How are business and institution-specific databases different?
Business database compilers attempt to identify and collect information on all 15,000,000 entities. Compilers of institutional data are not driven by SICs and frequently don’t even use them. They collect data only where there is market demand and where high quality, well-defined data sources are available. The data is often telephone verified and personal names and appropriate attributes are added. Applying business attributes like number of employees or sales volume just doesn’t work well when you’re trying to reach institutions.
