Distributed Databases Questions
Data consistency in a distributed database refers to the property that ensures all copies of the data stored across multiple nodes in the database are synchronized and up-to-date. It means that any changes made to the data in one node will be reflected in all other nodes, ensuring that all users accessing the database see a consistent view of the data.
Data independence in a distributed database refers to the ability to access and manipulate the data in the database without being concerned about its physical location or the specific details of how it is stored. It allows applications and users to interact with the database using a common interface, regardless of the underlying distribution and organization of the data. This independence ensures that changes in the distribution or structure of the database do not require modifications to the applications or queries accessing the data.
