Activity diagram uml11/9/2023 ![]() ![]() The focus of this paper is on consistency between the UML diagrams to Z Schema, and then verified by using the Z / EVEs tool. This paper proposes an approach involves the combining UML use-case diagram and activity diagrams with Z language for formalization of Library Management System (LMS). Therefore, an integrated between UML specification and formal specification is required to reduce the requirements' ambiguity and error, and to improve the quality and security of software systems. It applied in early stages of Software Development Life Cycle (SDLC). On the other hand, formal methods are techniques and tools use the mathematical notations, and they involve the precise syntax and semantics of the unambiguous software requirements specification. However, the ambiguity of semantics and the absence of consistency among UML diagrams lead to lack of precisely defining the requirements of a system. Choose Control Flow > Activity Final Node on the popup window.Unified Modeling Language (UML) is the effective standard for modeling object-oriented software systems. To create an activity final node, select the final action ( Log Shipment in this case), click the resource button, then drag to the desire position and release.Repeat step 11 when creating more decision nodes.You are allowed drag and move the caption of a decision node. Choose Control Flow > Decision Node on the popup window. When creating a decision node, click action that you would like to connect with ( Contracts Agents Reviews Order in this example), click and hold the resource button, then drag to the desire location and release.You can rename the action afterwards by double clicking the action. When release the button, choose Control Flow > Action. ![]() To create an action, click the initial node, click and hold the resource button, then drag to the desire location.In this tutorial, we would like like the activity starts from the Customer participant. Create the initial node by selecting Initial Node, then click on the participant where you want the activity starts.To create more partitions, right click any empty space on the swimlane, then select Add Vertical Partition.The first two participants in this tutorial are Customer and Sales. ![]()
