What are the differences in validation between MongoDB and SQL?
MongoDB uses a flexible schema, allowing for dynamic validation, while SQL enforces a strict schema with defined data types.
Can you explain how validation works in MongoDB?
In MongoDB, validation rules can be defined using JSON Schema, allowing you to specify required fields, data types, and more.
What about SQL? How is validation handled there?
In SQL, validation is typically done through constraints like NOT NULL, UNIQUE, and CHECK, which are defined at the table level.
Which one is better for data integrity?
SQL is generally better for data integrity due to its strict schema and constraints, while MongoDB offers flexibility at the cost of some integrity.
