When a flowchart becomes too large to fit on one page, the off-page connector symbol can be used to show where the flow leaves off on one page and then where it picks-up on a different page. When a flowchart becomes too complicated and flowlines cross each other, an on-page connector can be used to show where to connect next without crossing lines. The manual operation flowchart symbol is used to show that a user performs a manual operation within the flow which is other than simply data input. If multiple documents are used, multiple document symbols can be overimposed and slightly offset. The document flowchart symbol represents a single document (ex: PDF, Word, etc.) used within the flow being documented. The database flowchart symbol is used to depict storage of data (it could be a database, a file, etc.) and it could be used either to read data from or write data to. The manual input flowchart symbol is used to show that a human is performing data entry or providing information to the system. This flowchart symbol depicts that at this point in the flow data is either entred into the process/system or data is being output from the process/system. The flowchart decision symbol is very similar to the decision symbol of other diagraming techniques and issued to show where a given process or flow can split into two or more branches based on a decision condition. If a given sub-process or segment of a process is reused, it can be defined once and then specified again using the pre-defined process symbol. The flowchart pre-defined process symbol depicts the fact that this step is decomposed in detail in a different diagram or page. Generally used to depic an action which takes place in the system or which uses the system. The process flowchart symbol represents an action or activity which takes place at the given step in the process. A flowchart should have only one beginning symbol. This flowchart symbol represents either the beginning of the flow or the end of the flow. It is terminated with an arrow to show the direction of the flow/process (generally top to bottom or left to right). The flowline represents the standard connector of the rest of the symbols in a flowchart. The flowchart diagram is drawn using a set of standard flowchart symbols including: The flowchart is very similar in uses and functions as the UML activity diagram and the BPMN process diagram. More specifically a flowchart refers to a very specific type of structured workflow diagram which has been adopted by the International Organization of Standardization (ISO) and updated in 1985 with ISO 5807. A flowchart diagram or just flowchart is a term generically used to refer to a diagram which shows the flow of a process (step by step).
