What is a Data Type?

• A data type is one of the building blocks of any programming language or database. Data type acts as a classifier that specifies the type of data that a particular object or variable can hold.
• With the help of the data types, a developer knows which value a variable can hold or which value is valid for a variable and, what operations can be performed on those values.
• Data types are a way to organize data in its correct categories.
• The choice of data type depends on the requirements of the application in which the data is used.
• There are several types of data types in MongoDB. Let’s explore different types of data types in MongoDB.

Data types are fundamental to programming languages and databases, acting as classifiers that specify the kind of data an object or variable can hold. They help developers understand the values a variable can store and the operations that can be performed on those values.

In MongoDB, a popular NoSQL database, there are several data types available to handle a wide range of data types. In this article, We will see what are the data types in MongoDB and multiple methods through which we can easily change the type of a field.
