There are many different artifact types in business process modeling. Artifacts allow you to visually represent objects outside of the actual process. Artifacts can represent data or notes that describe the process, or they can be used to organize tasks or processes. There are 3 main types of artifacts: data objects, annotations, and groups.

Data objects are pretty self-explanatory. They represent either data placed to the process, data resulting from the process, data that needs to be collected, or data that needs to be stored.
Tasks are often data-dependent. Data inputs represent those data requirements of the business process.
If a process generates data, a data output represents the information produced as a result.
Data collection is denoted differently than a one time data requirement.
Data storage provides the ability to store or access data that is associated with a business model.
Annotations allow the modeler to describe additional flow parts of the modeling notation.
Groups organize tasks or processes that have some kind of significance in the overall model. To the left is a symbolic notation of the previously discussed artifacts.
