What is a Data Store in BPMN?

A Data Store represents persistent data storage like databases or file systems. It exists beyond individual process instances and can be accessed by multiple processes.

When should I use a Data Store?

Use Data Stores to show where persistent data lives-customer databases, document repositories, inventory systems. They indicate shared data that multiple process instances access.

How is the Data Store different from related elements?

Data Stores represent persistent repositories accessed by many instances. Data Objects represent data flowing through one instance. Data Stores use cylinder shape; Data Objects use document shape.

Key Characteristics

Persistent storage: Data exists beyond individual process instances
Shared access: Multiple processes and instances can access the same store
External systems: May represent databases, CRM systems, ERP data
Read/write operations: Activities connect to read from or write to the store

Customer Database
