When should you use a database instead of a file?

Question

Databases support good data access because: Large volumes of data can be stored in one place. Multiple users can read and modify the data at the same time. Databases are searchable and sortable, so the data you need can be found quick and easily. The data structure is extendable and can be modified as requirements change.
