Distributed Databases Questions
Data security in a distributed database refers to the measures and mechanisms put in place to protect the data stored in the database from unauthorized access, modification, or destruction. It involves implementing authentication, authorization, and encryption techniques to ensure that only authorized users can access and manipulate the data, while also preventing any unauthorized or malicious activities.
Data independence in a distributed database refers to the ability to access and manipulate the data stored in the database without being affected by the physical or logical distribution of the data. It allows users and applications to interact with the database without needing to know the specific location or structure of the data. This independence is achieved through the use of data abstraction layers and standardized query languages, which provide a consistent and unified view of the distributed database regardless of its underlying architecture or distribution.
