15. Extract & Normalize the document structure 3/5 normalized table structure 1/3 main table: events id  int, Primary Key eventname  int, not NULL  table: eventnames start  int, not NULL  table: times finish  int, not NULL  table: times date  int, not NULL  table: dates room  int, not NULL  table: rooms lecturer  int, not NULL  table: lecturers comment  varchar(200) unknown  varchar(200) Sebastian Burkart & Patrick Reichert

16. Extract & Normalize the document structure 4/5 normalized table structure 2/3 table: eventnames id  int, Primary Key eventname  varchar(200), unique, not NULL table: times id  int, Primary Key Time  varchar(10), unique, not NULL table: dates id  int, Primary Key date  date, unique, not NULL Sebastian Burkart & Patrick Reichert
