Whenever a CRUD (create, replace, update, delete) operation is performed on a fundamental GOCDB&nbsp;objects (site, service endpoint, downtime, user, user role) the regional GOCDB&nbsp;will record the event. This record will include the object Id, the type of operation&nbsp;(CRUD)&nbsp;and the date and time at which the object was modified. The record will also show whether the object has been successfully synchronised with the central GOCDB via a synchronisation boolean. By default the synchronisation field will be false.<br>
 
This table will be used to create a set of PI&nbsp;queries exposing EGI data that has changed in a regional GOCDB:
 
*gocdbpi/?method=synchronise_egi_sites
 
*gocdbpi/?method=synchronise_egi_service_endpoints
 
*gocdbpi/?method=synchronise_egi_downtimes
 
*gocdbpi/?method=synchronise_egi_users
