# Introduction In this lab, you will learn how to validate MongoDB data types, handle invalid data, and prevent bad input to maintain data integrity in your MongoDB database. You will start by exploring the different data types supported by MongoDB and creating a sample collection with specific data type requirements. Then, you will practice inserting documents with incorrect types and learn how to correctly insert data that meets the validation criteria. By the end of this lab, you will have a solid understanding of MongoDB data validation and error handling techniques.
