Very large database

This article is about Large size databases. For International Conference on Very Large Databases, see VLDB.

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.

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