Property (element)

From JRapid

Jump to: navigation, search

property is an element, child of entity.



Entities are composed mainly of properties. Each property may be referred as a field in the entity's form, or a column in the entity's database table. Properties store values, collections of values, or relationships with other entities.

JRapid properties are defined by their type. This may be a built-in data type, such as string, integer or date, or it may be an entity-type.

Properties may specify many attributes that customize their behavior.
