Logical Data Modeling - Field

About

A field is a container for one or more values with:

• a identifier (name and/or position)
• and a data type

You can see a field as:

• a variable with a data type
• a cell in a element set (ie in a table, csv or spreadsheet)
• a relational column
• a key-value in a tuple
• one value of an attribute with the same property

Collectively, they represent the state of a data model element.

You should be able to reference a field by:

• name
• or position
