Small Data Integration: What Is It? Data integration solving lots of jigsaw puzzles Each jigsaw puzzle e. g, Ta j mahal) is an integrated entity Each piece of a puzzle comes from some source Small data integration solving small puzzles
“Small” Data Integration: What Is It? Data integration = solving lots of jigsaw puzzles – Each jigsaw puzzle (e.g., Taj Mahal) is an integrated entity – Each piece of a puzzle comes from some source – Small data integration → solving small puzzles 10
