如何计算Database Size

learn.whatIsHeading

A database size estimator calculates expected storage requirements based on row count, average row size, indexes, and growth rate. Proper sizing prevents disk space exhaustion and helps with backup planning; most databases grow 20–50% larger than raw data size due to indexes.
