Reporting: Is there a list of tables most commonly used in reports for INC, CHG, REQ, and what they include?

[Tracy Pfahl]

For reporting on Incident, Change and Request, there are a group of standard tables we use repeatedly (listed below).  Does anyone know of a summary of these common tables that describes when to use one over the other based on the data you are targeting?  
Thanks, 
Tracy

1. sys_user
2. sys_user_has_role
3. sys_user_grmember
4. task
5. task_sla
6. change_request
7. cmdb_ci_computer
8. cmdb_ci_outage
9. cmdb_ci
10. sn_customerservice_case
11. incident
12. incident_sla
13. kb_knowledge
14. kb_use
15. sc_req_item

You can just use the task table and use the task type filter to choose type of task.

For example:

Task Table chosen

Filter chosen is  task type= incident/incident task/Catalog task
