The first step for Polk was to standardize the process of integrating 240 differ- ent data sources. The developers used SOA to help them take advantage of the similar elements found in many of the data sources.
Polk began to make the integration process more efficient by referencing one common master tag library.
The processes of capturing, standardizing, and enhancing the data are all leading to the creation of a “single source of truth” — data that is con- sistent regardless of the original source of the data.
The process of integrat- ing the automotive industry data from multiple sources was automated for delivery to Polk’s 50+ analytical and operational applications.
