Resource data history table in Altiris database

HI all,

I am designing a customized report which the removal date of software will be shown. The screenshot is showing the resource data history of a computer.

I am finding the date of action snapshot as like as the red box below. Do anyone know which table is storing the resource data history in Altiris database?

My Altiris version is 7.6 HF7 and the operating system is Windows Server 2012 R2.

The SQL server version is 12 sp3. 

Thanks.
