BUILDING BLOCK - Bounded Aggregate

Description	Abstract Concept A Bounded Aggregate is an Aggregate Entity Block which hides its internal structure to the outside world by means of formal Borders. The only way to access a Bounded Aggregate is through its formal Borders, which ensures the aggregate's internal consistency. The Borders of a Bounded Aggregate is determined by the Connection Relationships it can participate to. Within a Bounded Aggregate structure, Bounded Members can be linked together through Connectors. The nature of Connectors is given by their associated Connection Relationship. Examples: - Action Processes are bounded by their start and end events (see Behavioral Event). - Applications are bounded by their APIs borders (API Service Point and API Request Point).

Relationship Table

Relationship	Cardinality	Target Entity	Source Entity	Description
Exit Border	[*..0]	Connection Relationship	Bounded Aggregate	An Exit Border is a Border of a Bounded Aggregate that serves as a connection point allowing Bounded Members to connect to external Bounded Aggregates.Examples: an Exit Border can be physical (such as a door or gateway), functional (such as requested API endpoint in software or the End Event of a process).
Entry Border	[*..0]	Connection Relationship	Bounded Aggregate	An Entry Border is a Border of a Bounded Aggregate that serves as a connection point allowing external Aggregate Blocks to access Aggregate Members within the Bounded Aggregate.Examples: an Entry Border can be physical (such as a door or gateway), functional (such as an API endpoint in software or the Start Event of a process).
Bounded Member	[*..0]	Bounded Aggregate	Aggregate Entity Block	A Bounded Member is an Entity Member that aggregates a Bounded Aggregate.Bounded Members can be related by means of Connectors which connect an Exit Border of a source Bounded Member to a corresponding Entry Border of a target Bounded Member.
Unbounded Member	[*..0]	Unbounded Aggregate	Aggregate Entity Block	An Unbounded Member is an Entity Member of an Aggregate Entity Block that aggregates an Unbounded Aggregate.Because Entity Members do not have borders, Unbounded Members cannot be related by Connection Relationships (see Bounded Aggregate).
Connector	[*..0]	Connection Relationship	Aggregate Entity Block	A Connector is Block Member that connects a source Bounded Member to a target Bounded Member through their Entry Border and Exit Border.The semantic of Connector is given by their associated Connection Relationship.Examples:. Event that manifests a transition between two states.. Sequences between the end of a process step and the start of another process step.. Interface connection between a service consumer agent and a service provider agent.
Hierarchical Member	[*..0]	Building Block	Aggregate Block	A Hierarchical Member is an Aggregate Member that is also a Block Lexical Scope for the Building Block it aggregates: it relates its aggregated block by nesting (see Nesting Relationship).Hierarchical Members are used to build hierarchical structures of Building Blocks, in constrast to Block Members which are used to build network structures of Building Blocks.
Block Member	[*..0]	Building Block	Aggregate Block	A Block Member is an Aggregate Member that aggregates its releated Building Block by reference (see Referencing Relationship).Block Members are used to build network structures of Building Blocks while Hierarchical Members are used to build hierarchical structures of Building Blocks.
