Properly prepared data collects a lot of technical metadata describing the form and content of data that a business glossary links to terminology business users will understand. Lineage involves knowing not just where data came from but also whether it came directly from a source or passed through a process, system or application before analysis. The data lineage aspects of a business glossary supports analytics by providing an audit trail for post-decision defenses and post-outcome accountability. Artificial intelligence (AI) applications are driven by analytics that require massive amounts of high-quality data to achieve their goals. A business glossary improves the quality of data by augmenting data with the tacit knowledge of users who understand what the 1's and 0's mean in the ABCs of the business.
