ObjectId: 
Object Id the record id, for which this audit record is created.

UserId:
The user who performed action on record. 

ChangeData:
Change Data column stores old data for the attribute. If you changed First name of contact from James to Jim, then in Change data James will be stored.
Values in Change Data are stored in same order as attribute mask stored.
If First name attribute mask is 2 and last name is 3, then in AttributeMask it would be ,2,3 and Change data would be James~Bond

Change Data column data is separated by ~ by per attribute.

Operation:
Operation column stores information of what kind of operation is performed on record.
CRM has only four operations
1 - Create , 2 - Update, 3 - Delete, 4 - Access. 

To get directly operation values from database use

SELECT Value,AttributeValue FROM StringMap WHERE AttributeName='operation'

ObjectTypeCode:
Object Type code is entity object type code.

To find object type code for entity use

SELECT ObjectTypeCode, LogicalName FROM Entity WHERE Name='contact'

If want to get entity details from object type code then use

SELECT ObjectTypeCode, LogicalName FROM Entity WHERE ObjectTypeCode=1
