Hi @DishaSharma ,
Adobe Campaign uses two additional separate tables- NmsRtEvent and NmsBatchEvent
NmsRtEvent let's you manage real time events.
NmsBatchEvent manages batch events.
PushEvent lets you insert a single event into the message whereas , PushEvents lets you insert a series of events into the message.
The PushEvent method is made up of a <urn:domevent> parameter which contains the event.
The PushEvents method is made up of a <urn:domeventcollection> parameter which contains events.
