Document Flow System Simulation

feature design:

1. Document fiction : to create a new electronic documents, electronic documents created upload operation.

2. Sign documents: when the recipient receives the document, the sender will send a receipt message confirming document has been received.

3. Browse documents (the documents have been received):

   1) Select the date segments.

   2) the "Query" function displays the time period has passed Shenqian of official documents.

   3) Click the document title, it will show the specific information of the document.

4. Review documents: for fiction good electronic document for formatting operation , apply the sample document.

5. Document Flow: receiving a user document setting process according to the document flow .

6. Delete documents: If the document is not approved or Shenqian , you need to delete can use the " delete " function. OK, the system prompts documents deleted successfully, delete the document will "be deleted documents Display" module.

7. Send document: Operator To send a document flow process unit according to the administrator of the selected document , implement and outgoing documents have been sent document management

8. Audit documents (revised and signed opinion): to sign audit opinions and amendments, and return the office.

9. There Shenqian document (revised and signed opinion): the signing of pre-trial comments and amendments, if agreed, generate official documents and handed over office forwarded.

10. Browse all the documents have been issued: View all sent documents by date, click on the title to view details.

11. Document query : query processing by the document exchange system over the documents, and to establish or check the documents detailed index information. The transmission mechanism may be, receiving means, the type of documents and other information open document data query .

12. System Management :

    1.  Configuration management role

       1. User permissions maintenance functions: user management roles.

       2. Role maintenance functions: management role permissions, mainly to edit, add, and delete operations.

    2. User Management: View user opened a new user, Suspend user, modify user information, delete users

    3. Unit Administrator to set function: the operator for each unit to achieve change passwords, modify personal information.

 Most of my programs are not implemented, since that only completed less than one-tenth of the basic features for the entry and log in.
