A distributed database is a system of databases stored across multiple physical locations, which can improve performance by allowing transactions to be processed on many machines. It is kept up-to-date through replication and duplication processes, and there are various technologies used to ensure data security, consistency and integrity. Microsoft and Oracle provide different views on accessing distributed databases.
