A flowchart is a type of diagram that represents a workflow or process. A flowchart can also be defined as a diagrammatic representation of an algorithm , a step-by-step approach to solving a task. The flowchart shows the steps as boxes of various kinds, and their order by connecting the boxes with arrows.
A sequence diagram shows, as parallel vertical lines (lifelines), different processes or objects that live simultaneously, and, as horizontal arrows, the messages exchanged between them in the order in which they occur. This allows for the graphical specification of simple runtime scenarios.
A Message Flow is represented with a dashed line, an open circle at the start, and an open arrowhead at the end. It tells us what messages flow across organizational boundaries (i.e., between pools). A message flow can never be used to connect activities or events within the same pool. Association An Association is represented with a dotted line.
A binary association is represented as a solid line between two classes. A reflexive association is a binary association between the class and itself. An association between more than two classes is represented as a diamond connected with a solid line to each of the associated classes. An association between three classes is a ternary association.
The swimlane flowchart differs from other flowcharts in that processes and decisions are grouped visually by placing them in lanes. Parallel lines divide the chart into lanes, with one lane for each person, group or sub process. Lanes are labelled to show how the chart is organized.
A dashed line with an open arrow pointing away from the source to the target is used to represent information flow. The keyword "flow" may be written above or below the dashed line. Information items represent the abstraction of data and act as information flow connectors, representing the flow of transfer of information from source to target.

The name of the warehouse is a plural noun (e.g. orders)—it derives from the input and output streams of the warehouse.
This is a simplified flowchart process flow chart in which columns are tasks, rows are roles, and dots that are inserted at the intersection of tasks and roles represent a sequence of steps. In other words, it is an extensive RACI table with additional information about the sequence of steps in the process.
