From Wikipedia, the free encyclopedia
Jump to: navigation, search

A very large database, or VLDB, is a database that contains an extremely high number of tuples (database rows), or occupies an extremely large physical filesystem storage space. The most common definition of VLDB is a database that occupies more than 1 terabyte or contains several billion rows, although naturally this definition changes over time.[citation needed]

Very large databases are often, but not necessarily, a core component in big data analysis.
