Chapter 4 Building an Analysis Business Process Model
A data allows you to identify the type of information exchanged between business processes at a high conceptual level, focusing more on the semantic of the information than on technical aspects, such as physical data type, check parameters, etc. Business processes exchange information using resource flows and process flows.
A data can be attached to:
| When a data is... | It allows you to... |
|---|---|
| Transported by a flow or a resource flow | Identify the type of information exchanged between a resource and a process or between processes |
| Associated with a message format | Identify the type of information a message format can represent |
| Used by a process | Identify the type of action the process does on the data for the process to be executed |
For more information about how to attach a data to a flow or resource flow, to a message format or to a process, see the "Selecting data for a flow or a message format" section, and the "Selecting data for a process" section.
A data can be transported by several flows and message formats, but a flow or a message format cannot transport the same data twice. Same for the process, which cannot use the same data twice.
You can specify a type to a data and link the data to an object in order to specify the nature of the piece of information exchanged between business processes. Structured data can also have sub-data to specify their decomposition. A sub-data is also a data.
A data can have the following types: Undefined, Elementary, and Structured.
For more information about data types, see the "Data property sheet Definition property" section.
Business data can be considered as the entry point for specifying structural elements that you can analyze afterwards in Conceptual Data Models, Physical Data Models or UML Class Diagrams.
A data belongs to a package and can be referenced in other packages.
A data has no graphical symbol. You can nevertheless display a list of data on the flow symbol.
For more information about how to display a list of data on a process flow symbol or resource flow symbol, see Flows (BPM) or section see Resource Flows (BPM).
Data are not available in the executable and collaborative Business Process Models.
