FIELD (COMPUTER SCIENCE)

In computer science, data that has several parts can be divided into 'fields'. For example, a computer may represent today's date as three distinct fields: the day, the month and the year.
Programming languages usually have a record data type to represent composite data types as a series of ''fields''. An array of boolean values can be represented as a ''bit field''.
Relational databases arrange data as sets of database records, also called rows. Each record consists of several ''fields''; the fields of all records form the columns.
In object-oriented programming, ''field'' (also called ''data member'') is the data encapsulated within a class or object. In the case of a regular field (also called ''instance variable''), for each instance of the object there is an instance variable. A static field (also called ''class variable'') is one variable, which is shared by all instances.
