How to model list attribute

Data Vault 2.0
1

HI, I`m trying to model the case as below.

Source Table (Task ID | Attr1 | Attr2 | Countries | Products | LastModificationDate), is providing attributes for Tasks, all the attributes are single valued, except Countries and Products, which are lists/arrays and can contain 0…n elements each.

Model which so far I come to is as following:
HUB_Tasks (Task ID)
SAT_Tasks_Details (Attr1 | Attr2 | LastModificationDate)
SAT_MAS_Tasks_Countries (record for each country element and LastModificationDate)
SAT_MAS_Tasks_Products (record for each product element and LastModificationDate)

Could you please advise if this is right/best way of doing it? What better options you could propose please?

Why do you need to split them out into MAS? Querying?

Hi, the main reason of doing so - to secure atomicity.

Option B would be to use stringified values of array, treat them as a singe-valued fired in the model and include them along with other fields into the single sat/hash calculations.

Do you think option B is a better way?
