Activity diagrams [1] are graphical representations of workflows of stepwise activities and actions [2] with support for choice, iteration, and concurrency. In the Unified Modeling Language, activity diagrams are intended to model both computational and organizational processes (i.e., workflows), as well as the data flows intersecting with the related activities.
An activity diagram, with the activity "Cooking Spaghetti" outlined with an "Activity frame" An activity in Unified Modeling Language (UML) is a major task that must take place in order to fulfill an operation contract. The Student Guide to Object-Oriented Development defines an activity as a "sequence of activities that make up a process."
E-commerce is supported by electronic business. [3] The existence value of e-commerce is to allow consumers to shop online and pay online through the Internet, saving the time and space of customers and enterprises, greatly improving transaction efficiency, especially for busy office workers, and also saving a lot of valuable time.

Diagram illustrating how the relative emphasis of different disciplines changes over the course of the project. The unified process is an iterative and incremental development process. The elaboration, construction and transition phases are divided into a series of timeboxed iterations. (The inception phase may also be divided into iterations ...
Generic editors for generic diagrams, generic tables and generic trees. All available icons can be used and no syntactic diagram constraints are checked. Unified Modeling Language (UML) editors for static structure (i.e. class and object) diagrams, use-case diagrams, activity diagrams, statecharts, collaboration diagrams, component diagrams and ...
It is often indicated by a thin box or bar superimposed on the Object's lifeline in a Sequence Diagram; Activity diagram - a diagram that describes procedural logic, business process or work flow. An activity diagram contains a number of Activities and connected by Control Flows and Object Flows. Active class - a class defining active objects
An activity is a generic term for work that a company performs. It can be atomic or compound. Task A task represents a single unit of work that is not or cannot be broken down to a further level of business process detail. It is referred to as an atomic activity. A task is the lowest level activity illustrated on a process diagram.
Similarly, in UML, a standard concept-modeling notation used in software development, the activity diagram, which is a type of flowchart, is just one of many different diagram types. Nassi-Shneiderman diagrams and Drakon-charts are an alternative notation for process flow.
