اقتباسCreate a single script called h3a which creates, constrains, and populates the following tables: mountains, climbers, expeditions, and members. The semantics are:
An expedition is an attempt to climb a mountain.
Each mountain can have multiple expeditions.
Each climber can be a member of multiple expeditions.
Each expedition consists of many climbers
The structure of your tables is:
Mountain {name, height, location}
Climber {name, gender, birthday}
Expedition {expid, expname, mountainname, start_date, summit_date}
Member{expid, climbername, height_achieved, obit}
Constrain your tables with all appropriate Primary Key, Foreign Key, and Check constraints. Remember:
