Notation legend

  1. Entity: Links to the most relevant guide (if exists).
  2. Cardinality: Written besides an entity, this denotes allowable number of instances. For example, 1..* means that one or more are allowed.
  3. Object/Class: Denoted by a fixed-width font, links to the latest reference page.
  4. Grouping: Entities enclosed in a box belong to the box entity. For example, Campaigns belong to Account.
  5. Relationship: A solid line between two boxes establishes a relationship. Cardinality for the relationship is noted close to each end of a line. For example, zero to many Campaigns can be associated with zero to one Portfolio Bidding Strategy.
  6. Composition: Denoted by a solid rhombus, represents a relationship where an entity is composed of some other entities. When there is a number besides the rhombus, the number denotes the allowable number of instances. For example, an AdGroupAd is composed of one Ad object.
  7. Aggregation: Denoted by a rhombus, represents a relationship where an entity can contain one of other entities. For example, an Ad can contain either ExpandedTextAdInfo or TextAdInfo objects, but not both.
