Veracity refers to the messiness or trustworthiness of the data. Data by itself, regardless of its volume, usually isn’t very useful — to be valuable, it needs to be converted into insights or information, and that is where data processing steps in. Data quality pertains to the overall utility of data inside an organization, and is an essential characteristic that determines whether data can be used in the decision-making process.
