Which of the following places the common data elements in order f

SOLUTION

The correct answer is option 3 i.e character, field, record, file, database.

• A database is a collection of files, a file is made up of records, a record is made up of fields, a field is made up of characters, a character is made up of bytes and a byte is made up of bits (a bit is a short form for binary digit).
• When data is organized into a database, it becomes easy to access and manipulate. The most popular database form is the relational database.
  • Bit (Character) is the smallest unit of data representation (value of a bit maybe a 0 or 1). Eight bits make a byte which can represent a character or a special symbol in a character code.
  • The field consists of a grouping of characters. A data field represents an attribute (a characteristic or quality) of some entity (object, person, place, or event).
  • The record represents a collection of attributes that describe a real-world entity. A record consists of fields, with each field describing an attribute of the entity.
  • A file is a group of related records. Files are frequently classified by the application for which they are primarily used (employee file). A primary key in a file is the field (or fields) whose value identifies a record among others in a data file.
  • The database is an integrated collection of logically related records or files. A database consolidates records previously stored in separate files into a common pool of data records that provides data for many applications. The data is managed by systems software called database management systems (DBMS). The data stored in a database is independent of the application programs using it and of the types of secondary storage devices on which it is stored.
