A Data (Entity A) could be Sent (Relationship Name) to a Monitor (Entity B) or a Printer (Entity C) to be shown. In this case, the relationship between the Monitor and Printer at one side and Data at the other side is an Exclusive Relationship. Of course it is assumed that Data could be sent to only one of the targets at a time, not to both.
An entity may be defined as a thing that is capable of an independent existence that can be uniquely identified, and is capable of storing data. [5] An entity is an abstraction from the complexities of a domain.

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). For level 1 to 3, the C4 model uses 5 basic diagramming elements: persons, software systems, containers, components and relationships.
Possibly the most common use is in-memory objects in a computer program written in an object-based language. Information systems can be modeled with objects representing their components and interfaces. [1]: 39 In the relational model of database management, aspects such as table and column may act as objects. [2]
Elucidative Programming is the result of practical applications of Literate Programming in real programming contexts. The Elucidative paradigm proposes that source code and documentation be stored separately. Often, software developers need to be able to create and access information that is not going to be part of the source file itself.
Software development is the process of designing and implementing a software solution to satisfy a user.The process is more encompassing than programming, writing code, in that it includes conceiving the goal, evaluating feasibility, analyzing requirements, design, testing and release.
