xConnect is effectively a secure, scalable layer between your raw data (known as xDB) and the rest of your digital estate. In the past most, data was kept in an analytics silo however, this gave an unrealistic view of the interactions with your brand as it didn’t include offline interaction, mobile apps etc. xConnect can give a unified view of all the data.
Previously Sitecore analytics did measure this traffic however wasn’t very scalable so Sitecore has reworked their systems with xConnect.
