Partitioning a database improves performance and simplifies maintenance. By splitting a large table into smaller, individual tables, queries that access only a fraction of the data can run faster because there is less data to scan. Maintenance tasks, such as rebuilding indexes or backing up a table, can run more quickly.
Horizontal partitioning divides a table into multiple tables. Each table then contains the same number of columns, but fewer rows.
Vertical partitioning divides a table into multiple tables that contain fewer columns.
