What functionality does the Data Explorer provide in MongoDB?

The Data Explorer in MongoDB provides functionality that includes showing schema anti-patterns and collection statistics, which is key for understanding the structure and health of your data. This tool enables developers and database administrators to visualize and analyze the schema of their collections, identifying potential issues such as mismatched data types or inefficient data structures. By revealing schema anti-patterns, users can optimize their database design, leading to improved performance and more effective queries. Additionally, the collection statistics provided by Data Explorer give insight into the size, index usage, and document count of collections, which is essential for monitoring and optimizing database performance.

The other options do not accurately reflect the primary features of Data Explorer. While backups, data visualization, and file imports are important functionalities within the broader MongoDB ecosystem, they are not specific to the Data Explorer tool itself. This makes the identification of schema anti-patterns and collection stats the standout feature for this question.
