Object Document Mapper
An Object Document Mapper (ODM) is a programming tool that maps between objects in an application and documents in a NoSQL database, typically document-oriented databases like MongoDB. It allows developers to interact with the database using object-oriented paradigms, abstracting away the underlying database queries and providing a more intuitive interface for data manipulation. This simplifies database operations by enabling developers to work with data as objects in their programming language rather than writing raw database queries.
Developers should use an ODM when building applications with NoSQL document databases, as it enhances productivity by reducing boilerplate code and minimizing errors in query construction. It is particularly useful in scenarios involving complex data models, rapid prototyping, or when integrating with object-oriented languages like JavaScript (with Mongoose for MongoDB) or Python (with MongoEngine), as it provides validation, schema enforcement, and relationship management. This makes it ideal for modern web development, especially in MEAN/MERN stack applications where MongoDB is commonly used.
