Synchronization in UML (Unified Modeling Language) refers to the coordination and control of activities, events, or interactions among different objects, components, or processes in a system. It is particularly important in Object-Oriented Analysis and Design because modern software systems often contain multiple objects that execute operations concurrently or depend on one another. UML provides several mechanisms to represent synchronization and make the timing and coordination of system behavior understandable. One important feature of synchronization is the representation of concurrent activities. In UML Activity Diagrams, a fork node is used to divide one flow of control into multiple concurrent flows. These flows can execute simultaneously. For example, after receiving an online order, a system may simultaneously process payment, update inventory, and generate an order record. A fork visually represents this parallel execution. A join node is used to synchronize concurrent flows. It waits until all required incoming activities have completed
