What is the relation between database and instance?..

Answer / Krishna Kant Sharma

The Oracle Database and Instance are two different but closely related components of an Oracle database system. The database is a collection of data structures storing information, while the instance is the actual software that manages the database, including processes, memory structures, and background processes. In other words, an instance runs on one or more computer systems to support one or more databases.
