Table of related actions

--Act_re_procdef Process definition table
--act_re_deployment Deployment table
--Act_ge_property common property sheet ID generation policy
--Act_ru_execution execution object, process instance, process object
--act_ru_task Task table

Getting Started example:

1. Create process engine and workflow data table
-Databases and tables can be created automatically,
Enables automatic creation of databases and tables when you configure a database connection
-Get Processengine Object
First get the Processengineconfiguration object, and then the object to build the Processengine
2. Deployment process
Table of Influence:
ACT_RE_PROCDEF: Process Definition table:
The key attribute of the table is the BPMN ID decision
The Name property of the table is the BPMN Name property that determines
Act_re_deployment: Deployment table: ID is determined by Act_ge_property's next_dbid
Act_ge_property: Common attribute table
3. Start the process
4. View my personal tasks
5. Complete my personal tasks
