Explain the basic activity map condition thread nested activity map Using a lane usage example
Explanation
The business use case workflow illustrates the work that the service must be completed to provide its desired value to the service protagonist. Business uses consists of a series of activities that generate certain workpieces for business leads. Workflows typically include a basic workflow and one or more alternative workflows. The structure of the workflow uses the activity map.
Workflow activity maps are used to study the order arrangements of various tasks or activities to be implemented when the business goals are implemented. Events can be manually implemented tasks or automatic tasks. It can complete a work unit.
The activity map is a special form of the status map. All or most of these states are active status, and all or most of the transitions are triggered immediately when the activity in the source state is completed.
Basic activity map
A event map may include the following elements:
Active status indicates a certain activity or step in the workflow. Transfer is indicated in the order of the various active states. This transfer can be referred to as completion of the transfer. It is different from general transfer because it does not require a significant trigger event, but is triggered by completing the activity (represented by active status). Decision makes it a set of warning conditions. These alert conditions determine which transfer in a set of alternative transfer after the activity is completed. You can also use the determination icon to indicate the location of the thread to reconfigure. Decision and alert conditions allow you to display alternative threads in the workflow of business use. Synchronous schematic is used to display parallel branch. Synchronous schematic allows you to display parallel threads in the workflow of business use.

Condition thread
Alert condition is used to illustrate a certain thread in a set of parallel threads. For example, in the "Personal Registration" example of the above, the registered passengers may be a customer who travels frequently. In this case, you will need to reward some of the number of flying miles.

Nested activities
An active state may be referenced to another activity map because the latter shows the internal structure of the former. In other words, you can nested a map. You can display a sub-map in the active status or let the active status reference to another picture.
Nesting activity map in active state
If you want to display all workflow details in a picture, you can display a submap in the active status, which is not a convenient way. However, if the workflow shown is complicated, this will make the activity diagram difficult to understand.
Alternatively, the sub-map can be placed separately in one figure, and then let the active status reference it.
To simplify the workflow chart, you may want to put the sub-map in one figure, then let the active status described in detail in the subgraph to reference it.
Lane
The activity map can be divided into a lane using a vertical line. Each lane represents a certain part of the entire workflow, which is executed by a department of the organization. The lane can eventually be implemented by a class of organizational units or business object models.
Sort between lanes does not affect semantics. Each activity state assigned a lane, and the transfer may span several lanes.
The above activity diagram illustrates a business use case workflow representative of a general sales process. In this example, the lane represents the various departments in the organization.
Use example
Which one is the first use of the workflow activities and text descriptions? How much does this depend on your work habits, and whether you think in a chart. Some people tend to strip the outline of the structure in one figure, and then use the text. Others may be willing to develop an outline of the active status; after the agreement is achieved, the figure will be used to define the structure.
Another proper problem is whether you do need a text document. The activity map technology does allow you to write a brief description for each active status, which will make the textual status of the workflow is useless. In this case, you need to maintain a high degree of sensitivity to the statute format of the crowd and its expected.
We provide an example activity diagram for describing the workflow of the business use case "proposal process" defined in the guide: business use case. We use it to explain how the activity map helps deepen understanding of workflows. This example comes from a organization that sells telecommunications network solutions, each of which is tailored for customers.

Active state called "Working" includes three sub-steps that can be performed parallel. This is described in a sub-figure of this activity state.
Active status "Preliminary Operation Work" sub-map. You can choose to develop a sales plan, which will be explained through a warning condition in the upcoming transfer.
The active state can represent a considerable process (with sub-structure), or represent some relatively small processes. If you are using an active map to define the structure of the workflow, do not indicate all structural hies from the top to the bottom of the active map. This is likely to make the activity diagram very difficult to understand (if multiple separate submaps, the multiple maps will be difficult to understand). Should be as promitted to outline the entire workflow in one figure, where a few active status can have a sub-map.
