## WorkflowGen database

### The WorkflowGen database contains:

* User management<br>
* Process definition<br>
* Follow-up information about ongoing and closed processes, as well as significant workflow-related data (approvals, amounts, documents, etc.)<br>
* Files (such as PDF documents) are stored on the server and auto-archived in chronological order

## Applications

* XML transformation (for EAI features)<br>
* RAISEEXCEPTION to cancel one or many actions<br>
* Launch a new request from within an ongoing request<br>
* Develop your own workflow applications with the WorkflowGen development kit<br>
* Reuse existing compatible web services<br>
* Dozens of ready-to-use applications with source code examples available in the WorkflowGen Resource Center
