Abstract

This study focuses on the various consistency models are used in NoSQL databases. NoSQL databases are designed to handle large volumes of unstructured or semi-structured data, and they often use distributed architectures to achieve high scalability and availability. However, maintaining consistency across this type of database can be challenging due to the distributed nature of the database and the concurrent access of multiple users or applications. This study explores the different types of consistency models used in NoSQL databases. The study examines the strengths and weaknesses of each model and how they ensure data consistency and integrity in distributed databases. The findings of this study can help database administrators and developers choose the appropriate consistency model for their NoSQL database based on their specific requirements and use cases.

KEYWORDS: NoSQL, NoSQL-Database, DBMS, Consistency , eventual consistency
