1) Create the TIMES star schema dimension table via SQL. This is "TIME" table in the star schema figure. The Sale_Day primary key column values should be all dates from your first sale date through and including your last sale date from your SALES table. The Day_Type values should be 'Weekday', 'Weekend', or 'Holiday' (this trumps Weekday and Weekend). Set all occurrences of the following days for your date range to be holidays: New Years Day, Martin Luther King Jrs Birthday, Presidents Day, Memorial Day, 4th of July, Labor Day, Columbus Day, Veterans Day, Thanksgiving, and Christmas. Use a PL/SQL block to populate the TIMES table. After populating your TIMES table execute the SQL statement "SELECT day_type, COUNT(*),MIN(sale_day),MAX(sale_day) FROM time GROUP BY day_type ORDER BY day_type" to show the summarized contents of your table. Show all your SQL and PL/SQL code for this step and the results.
