Distributed Databases Questions
Data availability refers to the ability of users to access and retrieve data from a distributed database system. It ensures that data is accessible and usable by authorized users whenever they need it.
Data allocation, on the other hand, involves the process of determining where and how data is stored and distributed across multiple nodes or sites in a distributed database system. It involves deciding which data should be stored locally and which should be replicated or distributed across different sites to optimize performance, reliability, and availability.
In summary, data availability ensures that data is accessible to users, while data allocation determines how and where data is stored and distributed in a distributed database system.
