====== 12.2 Conceptual Elements Become Logical Elements ======
[[fxdemo:01-part:start | Go to Top ]]

The [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Architecture]] / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|PIM]] refines conceptual elements into platform-independent logical elements.

For example, Part 1 defines [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] as an architectural participant in a distributed [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_system|Financial System]]. Part 2 may define Logical Nodes and describe the responsibilities, interactions, and constraints.

Part 1 defines a [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoint]] as a point of information exchange used by one or more [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]]s. Part 2 may define logical endpoints, endpoint roles, endpoint relationships, and information-flow patterns without selecting a specific communication technology.

Part 1 defines [[dido:99_annexes:annex-b-terms-and-definitions:d:data_structure_definition|Data Structure Definition]] as a description of the [[dido:99_annexes:annex-b-terms-and-definitions:s:structure|Structure]], [[dido:99_annexes:annex-b-terms-and-definitions:s:semantic|Semantics]], and constraints of a class of information. Part 2 may define logical information structures, logical message classes, logical event classes, or logical record classes without binding them to IDL, JSON Schema, XML Schema, database schemas, or generated code.
