The data in MongoDB has a flexible schema?

19. The data in MongoDB has a flexible schema?

  1. True
  2. False

Answer: A) True

Explanation:

The data in MongoDB has a flexible schema. Unlike SQL databases, where you must first declare the schema of a table before you can insert data, MongoDB's collections do not enforce document structure before you can insert data. This type of adaptability is what distinguishes MongoDB as a powerful database.
