Distributed Databases Questions
Data consistency in a distributed database refers to the property that ensures all copies of data across different nodes in the database system are synchronized and up-to-date. It means that any changes made to the data in one node are propagated to all other nodes, ensuring that all users accessing the database see a consistent view of the data.
Data allocation in a distributed database refers to the process of determining how and where the data is stored across multiple nodes in the system. It involves deciding which data should be stored on which node based on factors such as data access patterns, performance requirements, and fault tolerance. The goal of data allocation is to optimize data access and minimize network communication overhead in a distributed database environment.
