A 30 byte name field may contain a person's name typically padded with blanks at the end.
A four byte field for example may contain a 31 bit binary integer plus a sign bit (32 bits in all). Fields are abstracted by properties, which allow them to be read and written as if they were fields, but these can be translated to getter and setter method calls.įields that contain a fixed number of bits are known as fixed length fields. A static field (also called class variable) is one variable, which is shared by all instances. In the case of a regular field (also called instance variable), for each instance of the object there is an instance variable: for example, an Employee class has a Name field and there is one distinct name per employee.
In object-oriented programming, a field (also called data member or member variable) is a particular piece of data encapsulated within a class or object. Each record consists of several fields the fields of all records form the columns.Įxamples of fields: name, gender, hair colour. Relational databases arrange data as sets of database records, so called rows. In computer science, data that has several parts, known as a record, can be divided into fields ( data fields).
