Distributed Databases Questions
Data security in a distributed database refers to the measures and techniques implemented to protect the data stored in the database from unauthorized access, modification, or destruction. It involves ensuring the confidentiality, integrity, and availability of the data, as well as implementing authentication, authorization, and encryption mechanisms to safeguard against potential security threats.
Concurrency in a distributed database refers to the ability to handle multiple concurrent transactions or operations on the database without causing conflicts or inconsistencies. It involves managing the simultaneous access and modification of data by multiple users or applications, ensuring that the database remains consistent and that transactions are executed correctly. Techniques such as locking, timestamping, and optimistic concurrency control are commonly used to handle concurrency in distributed databases.
