Description: The transaction model in NoSQL systems is a framework that defines how transactions are managed within a database. Unlike relational database systems, which follow the ACID model (Atomicity, Consistency, Isolation, Durability), NoSQL systems can adopt more flexible and scalable approaches to transaction management. This is because many NoSQL systems are designed to handle large volumes of distributed data and therefore prioritize availability and partition tolerance over strict consistency. In this context, the transaction model may include features such as eventual consistency, where data synchronizes over time rather than requiring all transactions to be consistent at all times. This approach allows applications to scale horizontally and handle massive workloads, which is essential in big data environments and real-time applications. Additionally, some NoSQL systems implement transactions at the document or document set level, allowing atomic operations in a more limited context, which facilitates data management without sacrificing efficiency. In summary, the transaction model in NoSQL is crucial for balancing the need for performance and scalability with data integrity in distributed environments.
