Final answer:
A DBMS is organized from the smallest unit, bit, to the largest unit, database. The order is bit, character, field, record, file, and database.
Step-by-step explanation:
A DBMS (Database Management System) is organized into several levels of abstraction to manage data efficiently. The smallest unit is the bit, which represents binary information, followed by the character, which is a symbol or letter. A field is a collection of characters that represents an attribute of an entity, and a record is a collection of fields that typically represents an entity or object. A file is a collection of records, and finally, at the largest scale, a database is a collection of related files that are managed by the DBMS.
Putting these in order from smallest to largest: bit, character, field, record, file, database.
