The document describes a webinar that demonstrates how semantic technology enables better decision making by providing the right data at the right time. It introduces semantic terminology and how semantic technology simplifies data federation. A case study is presented that analyzes post-discharge costs for heart attack patients through iterative analysis. The analysis uncovered unexpected results regarding rehabilitation hospital utilization and costs.

- 47. Conclusions • Data federation agility accelerates data analysis & reporting – Experts follow unexpected paths as they work with data – Predicting up-front what data will be useful • Error prone (too little missed) • Heavyweight (too much wasted effort) • Targeting federation at specific questions reduces the scope of data integration • Multiple iterations inform a broader data warehousing need (c) 2014 Blue Slate Solutions Semantics Underpins Analytic Agility 47
