System Dependency

System dependency refers to the relationship between different systems or components within a larger system. It shows which components rely on others to function properly, and how changes to one component can affect the others.

For example, if an application depends on a database to store and retrieve data, then a change to the database (such as an upgrade or maintenance) could affect the application’s performance. Similarly, if a server depends on a network to communicate with other servers or clients, then a network outage could disrupt the server’s ability to function.

Understanding system dependency is important for ensuring the reliability and stability of a system, and for planning upgrades or modifications. By identifying which components are critical and which are less important, organizations can prioritize their resources and investments accordingly.
