![]() Use of the proxy can simply be forwarding to the real object, or can provide additional logic. In short, a proxy is a wrapper or agent object that is being called by the client to access the real serving object behind the scenes. The proxy could interface to anything: a network connection, a large object in memory, a file, or some other resource that is expensive or impossible to duplicate. A proxy, in its most general form, is a class functioning as an interface to something else. In simple words, we can say that UML sequence diagram is a system that shows or explains the interactions between the elements of a computer network such as in case of email accounts, when to send the message and what message to be sent.In computer programming, the proxy pattern is a software design pattern. Most of the time, these diagrams are used for presenting the data or the system of the network on which it operates but due to the versatility of this technique, this diagram is also used to modify or define the architecture of an entire computer system in computer and network engineering. The most important part or factor about UML sequence diagrams is that these presentations provide a dynamic view of the system in an easy way which is quite hard and complex to understand in case of a static diagram. With UML sequence diagram, basically this is the system or method that is defined. This sequence decides the actions that are required to perform in order to complete a loop or circuit. Just like a cycle or any other type of project, when we talk about computer systems such as email or response for any action on the computer network, there is also a sequence present in this system. Here is preview of a Free Sample UML Sequence Diagram Template created using MS Word, For documentation purposes, UML sequence diagrams provide great ease to record and save the data at any point of the structure construction which is quite difficult to abstract from static images. Another key benefit of this technique is that these diagrams elaborate the complex system in easy and simple terms and figures which means even if any of the participant can’t understand the networking, the diagram will explain itself in very simple way. This means before you implement anything in real time, you can verify the authenticity and correctness of the system so that if there are any mistakes or errors in the programming, they can be eliminated or fixed in time. The most important thing about UML sequence diagram is that this tool let you know or find out about the system and its architecture before time. In this diagram, the time between the interactions or reactions against the actions is shown in vertical direction where the elements or the parts of the system are presented horizontally. In computer networking, UML sequence diagrams are frequently used because they are easy to generate and simple to understand. In between the components or elements of a system, sequence diagrams are used to present or show the relationship or link for the flow of events or messages. UML stands for Unified Modeling Language and sequence diagram is a very common and important technique for representing data and research in this field.
