- How to implement data transaction functions in MongoDB
- How to implement data transaction functions in MongoDB requires an overview of specific code examples: MongoDB is a non-relational database, and its default data operation mode is non-transactional. However, in some application scenarios, we need to ensure the transaction consistency and atomicity of the database. Since version 4.0 of MongoDB, the official transaction function has been launched, allowing developers to implement data transaction functions in MongoDB. Transaction: A transaction is the process of executing a set of database operations as a logical unit.

- Differences between RDBMS and MongoDB
- RDBMSRDBMS stands for Relational Database Management System. It stores data in entity form as tables. It provides multiple layers of information security. Each table may or may not have a primary key (used to uniquely identify records in the table) and foreign keys (used to identify the relationship between the two tables). RDBMS uses SQL language to query the database. Examples of popular RDBMS are oracle, sqlserver, mysql, etc. MongoDBMongoDB is a NoSQL database. It's open source. It is a document-oriented database that uses BSON (the binary version of JSON). BSON is a document storage format. MongoDB stores data in the form of documents and does not use SQL to query
