Data Models

Data in MongoDB has a flexible schema. Collections do not enforce document structure. Although you may be able to use different structures for a single data set in MongoDB, different data models may have significant impacts on MongoDB and application performance. Consider Data Modeling Considerations for MongoDB Applications for a conceptual overview of data modeling problems in MongoDB, and the Data Modeling Patterns documents for examples of different approaches to data models.
