The correct order of the Database Hierarchy from smallest to largest is: Bit, Byte, Field, Record, File, Database. This hierarchy represents the organization of data in database management systems.

  • A bit is the most basic unit of data in computing and represents a binary value (0 or 1). A group of 8 bits forms a byte, which is the smallest addressable unit of memory and can represent a single character, such as a letter or number.
  • A field consists of a set of related bytes that represent a single piece of information. For example, a field might hold a person's name or an address.

  • A record is a collection of fields that can be considered as a complete dataset for a specific entity. For instance, a record in a database could represent a single customer, consisting of fields like name, address, and phone number.

  • A file is a collection of records that are stored together. For example, a customer file might contain multiple records, each representing different customers.

  • Finally, a database is an organized collection of data that can include multiple files. It serves as a larger container that manages and organizes all related data efficiently.

This hierarchical structure helps in understanding how data is organized and accessed within database systems,
