We would like to have a RESTful web service that stores some transactions (in memory is fine) and returns information about those transactions. The transactions to be stored have a type and an amount. The service should support returning all transactions of a type. Also, transactions can be linked to each other (using a "parent_id") and we need to know the total amount involved for all transactions linked to a particular transaction. For example:

In detail the api spec looks like the following:

PUT /transactionservice/transaction/$transaction_id

Body:

{ "amount":double,"type":string,"parent_id":long }

where:

• transaction_id is a long specifying a new transaction

• amount is a double specifying the amount

• type is a string specifying a type of the transaction.

• parent_id is an optional long that may specify the parent transaction of this transaction.

**GET /transactionservice/transaction/$transaction_id ** Returns:

{ "amount":double,"type":string,"parent_id":long }

**GET /transactionservice/types/$type **

Returns: [ long, long, .... ]

A json list of all transaction ids that share the same type $type.

**GET /transactionservice/sum/$transaction_id **

Returns : { "sum", double }

A sum of all transactions that are transitively linked by their parent_id to $transaction_id.

Some simple examples would be:

• PUT /transactionservice/transaction/10 => { "amount": 5000, "type":"cars" } => { "status": "ok" }

• PUT /transactionservice/transaction/11 =>{ "amount": 10000, "type": "shopping", "parent_id": 10 } => { "status": "ok" }

• GET /transactionservice/types/cars => [10]

• GET /transactionservice/sum/10 => {"sum":15000}

• GET /transactionservice/sum/11 => {"sum":10000}
