Digital twins are commonly divided into subtypes that sometimes include: digital twin prototype (DTP), digital twin instance (DTI), and digital twin aggregate (DTA). [12] The DTP consists of the designs, analyses, and processes that realize a physical product. The DTP exists before there is a physical product.
For example, some authors use the concept of Digital Models (e.g., 3D models) and digital twin indistinctly considering them as interchangeable. [2] [3] However, a significant difference between digital twin and digital 3D models and systems exists and can be outlined based on different level of data integration and information exchange. [4]
The digital project twin evolved from the idea of the more general digital twin, which had historically been evolved from the aerospace industry.In the historical evolution, the conceptual foundation of a digital twin focusses primarily on physical environments that encompass a real object such as devices and machines with respective virtual environments.

The SAP architecture serves as an example in Digital Computer Electronics for building and analyzing complex logical systems with digital electronics. Digital Computer Electronics successively develops three versions of this computer, designated as SAP-1, SAP-2, and SAP-3. Each of the last two build upon the immediate previous version by adding ...
In software engineering, a software design pattern or design pattern is a general, reusable solution to a commonly occurring problem in many contexts in software design. [1] A design pattern is not a rigid structure to be transplanted directly into source code.
In software engineering, the Twin pattern is a software design pattern that allows developers to model multiple inheritance in programming languages that do not support multiple inheritance. This pattern avoids many of the problems with multiple inheritance.
In object-oriented programming, the singleton pattern is a software design pattern that restricts the instantiation of a class to a singular instance. It is one of the well-known "Gang of Four" design patterns , which describe how to solve recurring problems in object-oriented software. [ 1 ]
Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
