Communication Diagram UML2.0 / Collaboration UML1.x

"Communication diagram (called collaboration diagram in UML 1.x) is a kind of UML interaction diagram which shows interactions between objects and/ or parts (represented as lifelines) using sequenced messages in a free-form arrangement.
Communication diagram corresponds (i.e. could be converted to/ from or replaced by) to a simple sequence diagram without structuring mechanisms such as interaction uses and combined fragments. It is also assumed that message overtaking (i.e., the order of the receptions are different from the order of sending of a given set of messages) will not take place or is irrelevant."

The vector stencils library "UML communication diagrams" contains 23 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"... communication diagrams use the free-form arrangement of objects and links as used in Object diagrams. In order to maintain the ordering of messages in such a free-form diagram, messages are labeled with a chronological number and placed near the link the message is sent over. Reading a communication diagram involves starting at message 1.0, and following the messages from object to object." [Communication diagram. Wikipedia]

The vector stencils library "Bank UML communication diagram" contains 4 shapes for drawing UML communication (collaboration) diagrams.
Use it for object-oriented modeling of your bank information system.
"A communication diagram in the Unified Modeling Language (UML) 2.0, is a simplified version of the UML 1.x collaboration diagram.
A Communication diagram models the interactions between objects or parts in terms of sequenced messages. Communication diagrams represent a combination of information taken from Class, Sequence, and Use Case Diagrams describing both the static structure and dynamic behavior of a system.
However, communication diagrams use the free-form arrangement of objects and links as used in Object diagrams. In order to maintain the ordering of messages in such a free-form diagram, messages are labeled with a chronological number and placed near the link the message is sent over. Reading a communication diagram involves starting at message 1.0, and following the messages from object to object." [Communication diagram. Wikipedia]

Communication diagrams show a lot of the same information as sequence diagrams, but because of how the information is presented, some of it is easier to find in one diagram than the other.
Communication diagrams show which elements each one interacts with better, but sequence diagrams show the order in which the interactions take place more clearly." [Communication diagram. Wikipedia]

"The client–server model of computing is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. Often clients and servers communicate over a computer network on separate hardware, but both client and server may reside in the same system. A server host runs one or more server programs which share their resources with clients. A client does not share any of its resources, but requests a server's content or service function. Clients therefore initiate communication sessions with servers which await incoming requests.
Examples of computer applications that use the client–server model are Email, network printing, and the World Wide Web." [Client–server model. Wikipedia]

"The most common issue tracking system's design is relatively simple. A database is the main storage repository for all data. The data is managed by the business logic layer of the application. This layer gives the underlying raw data more structure and meaning, preparing it for human consumption. The now human readable data are then presented to the support technician by another software application or web page. The end-user of the issue tracking system can create entirely new issues, read existing issues, add details to existing issues, or resolve an issue. When a user of the system makes a change, the issue tracking system will record the action and who made it, so as to maintain a history of the actions taken. Each user of the system may have issues assigned to them, that is, that user is responsible for the proper resolution of that issue. This is generally presented to the user in a list format. The user may have the option of re-assigning an issue to another user, if needed. For security, an issue tracking system will authenticate its users before allowing access to the systems."
