Both TRTH V2 (historical DSS) and UPA or RFA get the raw real-time data from Elektron. However, TRTH V2 processes or adds values to the raw data before storing to its database.

UPA or RFA retrieves data in binary format. The application needs to decode the binary data before using it. For example, for MarketPrice domain, the binary data will be decoded to a field list contains field-value pair data , as shown below.

[FieldList]:  Dictionary ID: 1  FieldListNum: 99
PROD_PERM       213
RDNDISPLAY      153
DSPLY_NAME      Raiffeisen   MOW
TIMACT          08:49:00:000:000:000
NETCHNG_1       -0.0017
HIGH_1          1.1657
LOW_1           1.1617
CURRENCY        USD (840)
ACTIV_DATE      27 OCT 2017
OPEN_PRC        1.1648
HST_CLOSE       1.1650
BID             1.1633

However, the data from TRTH V2 is in JSON or CSV format. For "Tick history raw", the data looks like:

EUR=,Market Price,2017-07-22T00:05:06.885058466Z,+0,Raw,REFRESH,,,,,213,99,8975,317

...

The data is in CSV but it is still field-value pair data.

Therefore, it is correct to say that both RFA and UPA data is equivalent to "Tick history raw" and TRTH V2 processes this raw data to create "Tick history time and sales".

For "Tick History Market Depth", if you are using RawMarketByPrice, RawMarketByOrder, and RawMarketMaker view, you will see that the data is also equivalent to MarketByPrice, MarketByOrder, and MarketMaker domains in UPA and RFA.
