Data enrichment is one of the key processes by which you can add more value to your data. It refines, improves and enhances your data set with the addition of new attributes. For example, using an address post code/ZIP field, you can take simple address data and enrich it by adding socio economic demographic data, such as average income, household size and population attributes. By enriching data in this way, you can get a better understanding of your customer base, and potential target customers.
