A data structure diagram is a diagram type that is used to depict the structure of data elements in the data dictionary. The data structure diagram is a graphical alternative to the composition specifications within such data dictionary entries. [1] The data structure diagrams is a predecessor of the entity–relationship model (E–R model
Code diagrams (level 4): provide additional details about the design of the architectural elements that can be mapped to code. The C4 model relies at this level on existing notations such as Unified Modelling Language (UML), Entity Relation Diagrams (ERD) or diagrams generated by Integrated Development Environments (IDE).
The Object Constraint Language (OCL) for defining rules for model elements; The UML Diagram Interchange that defines how UML 2 diagram layouts are exchanged; Until UML 2.4.1, the latest versions of these standards were: [19] UML Superstructure version 2.4.1; UML Infrastructure version 2.4.1; OCL version 2.3.1; UML Diagram Interchange version 1.0.
The 4+1 view model is generic and is not restricted to any notation, tool or design method. Quoting Kruchten, The “4+1” view model is rather “generic”: other notations and tools can be used, other design methods can be used, especially for the logical and process decompositions, but we have indicated the ones we have used with success.
Compositional structure diagrams depict the static structure of a system, and the relationships between system components. System components can be active or passive. Agents are active system components. They perform activities in the system. Storages and channels are passive components which store or transmit information. The image to the ...
DSL elements can be converted to any subtype or a more general type using the “Convert to” function. DSL allows custom derived properties to be created that allow extending a UML metamodel or its profile. All DSL'ed elements can be numbered by using the generic numbering mechanism. The elements can be numbered in consecutive or multi-level ...

JSP is not used to structure programs at the level of classes and objects, although it can helpfully structure control flow within a class's methods. JSP uses a diagramming notation to describe the structure of inputs, outputs and programs, with diagram elements for each of the fundamental component types. A simple operation is drawn as a box.
