MongoDB is a powerful NoSQL database that can store and process large amounts of unstructured data. Like all databases, MongoDB uses data types to define the type of data that can be stored in each field of a document. In this guide, we'll explore the most commonly used data types in MongoDB and how to use them effectively in your applications.
The String data type is used to store textual data. It is the most common data type used in MongoDB and can store any Unicode character. Strings are enclosed in double quotes.
The Number data type is used to store numeric values. It can store integers and floating-point numbers. MongoDB supports 64-bit integers and double-precision floating-point numbers.
The Boolean data type is used to store true or false values. It is useful for storing flags and other boolean values.
The Date data type is used to store dates and times. It can store dates in either ISODate format or UNIX timestamp format.
5. Object ID
The Object ID data type is used to store unique identifiers for documents. MongoDB automatically assigns a unique Object ID to each document in a collection.
The Array data type is used to store lists of values. It can store a list of any data type, including other arrays.
7. Embedded Document
The Embedded Document data type is used to store nested documents within a document. It can contain any data type, including other embedded documents and arrays.
When using data types in MongoDB, it's important to choose the appropriate data type for each field to ensure data accuracy and efficient querying. Use the above guide to understand the most commonly used data types in MongoDB and how to use them effectively in your applications
