Here we provide several UML diagrams of different types, all part of a simple fabricated Online Shopping model:
SequenceDiagram.org is an online tool / software for creating UML sequence diagrams. Founded in 2014 with the purpose to improve the efficiency when creating and working with sequence diagrams by combining text notation scripting and drawing by clicking and dragging in the same model.
Opt is used to describe optional step in workflow. For example, for online shop purchase sequence diagram you may use opt to describe how user can add gift wrapping if she wishes. Alt may be used to describe two variants of payment: using credit card or wire money transfer. Apr 21, 2019 - Explore syamsiah suhaimi's board 'sequenceDiagram' on Pinterest.

This is the UML sequence diagram of Payment Management System which shows the interaction between the objects of Account, Payment Mode, Branch, Location, Bill. The instance of class objects involved in this UML Sequence Diagram of Payment Management System are as follows: Account Object. . A good sequence diagram is still above the level of the real code (not all code is drawn on diagram). Sequence diagrams are language-agnostic (can be implemented in many different languages). Non-coders can read and write sequence diagrams. Easier to do sequence diagrams as a team.

Project Sequence DiagramWeb application network diagram example
Purpose: UML provides no special kind of diagram to describe logical or physical network architecture of the designed or existing system. Deployment diagrams could be used for this purpose with elements limited mostly to devices with neither artifacts nor actual deployments shown.
Summary: This example of the network diagram shows network architecture with configuration usually called 'two firewall demilitarized zone (DMZ)'. DMZ is a host or network segment located in a 'neutral zone' between the Internet and an organization’s intranet (private network). It prevents outside users from gaining direct access to an organization’s internal network while not exposing a web, email or DNS server directly to the Internet.
Sequence Diagram Loop
(1) A customer service technician receives a telephone call, email, or other communication from a customer about a problem. Some applications provide built-in messaging system and automatic error reporting from exception handling blocks.
(2) The technician verifies that the problem is real, and not just perceived. The technician will also ensure that enough information about the problem is obtained from the customer. This information generally includes the environment of the customer, when and how the issue occurs, and all other relevant circumstances.
(3) The technician creates the issue in the system, entering all relevant data, as provided by the customer.
(4) As work is done on that issue, the system is updated with new data by the technician. Any attempt at fixing the problem should be noted in the issue system. Ticket status most likely will be changed from open to pending.
(5) After the issue has been fully addressed, it is marked as resolved in the issue tracking system.
If the problem is not fully resolved, the ticket will be reopened once the technician receives new information from the customer. A Run Book Automation process that implements best practices for these workflows and increases IT personnel effectiveness is becoming very common.' [Issue tracking system. Wikipedia]
The UML sequence diagram example 'Ticket processing system' was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
