Why MongoDB is Suitable for Beginners? Starting from Data Structures

The article points out that relational databases (such as MySQL) are not beginner-friendly because they require pre-designing table structures and handling complex relationships. In contrast, MongoDB lowers the entry threshold through its "collection + document" data structure. A MongoDB collection is similar to a "folder," and a document is like a "note," storing data in a JSON-like format where fields can be added or removed at any time without pre-planning the table structure. Its advantages include: 1. Data structures can be modified on-the-fly without writing SQL to create tables, directly storing data in an intuitive format; 2. It is as intuitive as writing JSON, requiring no additional learning of complex syntax; 3. Handling relationships with nested documents is simpler, avoiding complex operations like table joins. This flexible and intuitive structure allows beginners to focus on business logic first rather than getting stuck on database design, making it suitable for quick onboarding.
