Description

Abstract Concept
An Aggregate Block is a Building Block which has an internal structure made of Aggregate Members which, through nesting (Membership of -Aggregate Member-), contextualizes/aggregates (Aggregation of -Building Block- ) external Building Blocks within the Aggregate Block.

Structural Partition of Aggregate Block: an Aggregate Block is either an Ordering Connection or an Aggregate Entity Block

Functional Domain: Compositionality

The purpose of the Compositionality family of concepts is to provide syntactic mechanisms that support the construction of composite Building Blocks.

Relationship Table

Relationship	Cardinality	Target Entity	Source Entity	Description
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.
Aggregate Member	[*..0]	Building Block	Aggregate Block	Abstract Relationship An Aggregate Member is an Entity that serves as an internal constituent of an Aggregate Block, incorporating (aggregating) an external Building Block into its parent structure.Aggregation is the syntactic mechanism that enables the construction of modular, composite Building Blocks. It establishes a reified Relationship (the nested Aggregate Member) between the Aggregate Block and the aggregated Building Block, allowing the definition of local characteristic specific to the Aggregate Member. This mechanism facilitates the expression of emergent properties within the composite structure of the Aggregate Block .Examples:. Attributes of a UML class are Aggregate Members.. Steps of a process are Aggregate Members.. Specializations of a Class are Aggregate Members.
Existential Dependency	[1..1]	Entity	Entity	Abstract Relationship An Existential Dependency relationship is a Relationship where the source Entitys existence depends on the existence of the target Entity.The cardinality of the set of targetted Entity is [1..1].
Enumerated Definition	[1..1]	Ordering Connection	Aggregate Block
Enumerated Definition	[1..1]	Aggregate Entity Block	Aggregate Block
