NoSQL Database

Hi all,

I am a beginner with Oracle NoSQL so I explain my use case :

I have an object called Position coming from Coherence.

Position {
int id
string symbol
int amount
double price
}

I wonder what is the best way to store this object knowing that I want to do some queries like "select position from xxx where symbol = "ORCL", "select symbol, count(symbol) from xxx group by symbol" (I know we cannot use SQL it is just to give you easily an idea of my need)

1) Like that

majorComponents = new ArrayList<String>();
majorComponents.add("position");
majorComponents.add(String.valueOf(position.getId()));

myKey = Key.createKey(majorComponents);

myValue = Value.createValue(SerializationUtils.serialize(position));
store.put(myKey, myValue);

2) Or like that

majorComponents = new ArrayList<String>();
majorComponents.add("position");
majorComponents.add(String.valueOf(position.getId()));

minorComponents.add("symbol");

myKey = createKey(majorComponents, minorComponents);

myValue = Value.createValue(SerializationUtils.serialize(position.getSymbol));
store.put(myKey, myValue);

etc...with amount and price

Thank you for all...
