how does multiple receiving addresses works on bitcoin exchange?

[pavaya66]

i am working on project which allow users to send Some BTC to "xyz" address and allow each users to send etc to separate receiving address.

question 1: can bitcoind generate multiple receiving address with just one private key?
question 2: will all Btc End-ups in same wallet (Parent address/Parent private key/can use all transaction as single accumulated received Btc)
question 3: will i be able to send/spent all gathered etc from just single Private key?

I work on the business end of a blockchain development company. So I may not be the best at explaining this but I'll try. So when a new customer is created they are assigned an address. This is recorded in the SQL database under their account. The customer can create a new address. The database keeps track of all the addresses and to which customer they belong. You will have to configure the notifications to know when a transaction comes in and assign it to the customer based on which address.

Yes. It's all in the same wallet. If I access bitcoind directly and not through the software, I would then be able to send all the coin out from one wallet and not each individual address.

I'm sure I've butchered the technical details but this should give you a general idea of how it works from a layman perspective.
