Example- Two-tier architecture of the client and server for database application can be the train ticket reservation. The reservation made by a people will be according to the time , the person who gets chance to access the reservation first will get the ticket while others wait in queue.

If any query regarding the reservation according to the database occurs then Java Database connectivity (JDBC) will act as the middleware for the Java data collection between the application(client section) and database (server).

Explanation:

The UML scheme is a UML-based diagram intended to depict the system visually, together with its key actors, roles, activities, objects, and classes, to gather information the about system, change that, or maintain it.

Every complex process is better understood via sketches or pictures. These diagrams have a higher understanding effect. By glancing about, we notice that diagrams are not a new idea but are widely used in various business types. To enhance understanding of the system, we prepare UML diagrams. There is not enough of a single diagram to represent all aspects of the system. You can also create customized diagrams to satisfy your needs. Iterative and incremental diagrams are usually done.

There are two broad diagram categories and that they are broken into subclasses again:

  • Diagram structure
  • Diagrams of behavior

Please find the graph file of the question in the attachment.

Computer simulation refers to a mathematical model designed and developed to predict the outcome or behavior of a hypothetical or real-life scenario on a computer system, so as to illustrate and understand how the system functions.

Historically, computer simulations were first developed during World War II (WWII) as a part of the Manhattan Project.

For example, SimpleScalar refers to a computer architectural simulating software application or program which was designed and developed by Todd Austin at the University of Wisconsin, Madison, United States of America. It is an open source simulator written with "C" programming language and it's used typically for modelling virtual computer systems having a central processing unit (CPU), memory system parameters (hierarchy), and cache.
