MedDRA hierarchy is a system of organizing medical terms into categories based on their relationship to each other.

• MedDRA is organized into five levels of hierarchy

• The top level is System Organ Classes (SOCs), which are broad categories of related adverse events

• The second level is High Level Group Terms (HLGTs), which are more specific than SOCs

• The third level is High Level Terms (HLTs), which are more specific than HLGTs

• The fourth level is Preferred Terms (PTs), which are th...read more

Drop deletes the table structure and data, truncate deletes only data, and delete deletes specific rows.

• Drop: removes the table and all its data permanently

• Truncate: removes all data from the table but keeps the structure

• Delete: removes specific rows from the table based on a condition

• Drop and truncate cannot be rolled back, but delete can be
