What is VLDB?
VLDB stands for Very Large DataBase.
It is an environment or storage space managed by a relational database management system (RDBMS) consisting of vast quantities of information.
VLDB doesn’t refer to size of database or vast amount of information stored. It refers to the window of opportunity to take back up the database.
Window of opportunity refers to the time of interval and if the DBA was unable to take back up in the specified time then the database was considered as VLDB.
