CSC 513 Project 3: Validate XML

For this assignment, you will be defining the XML schemas for each of the messages to be sent between a customer, a serviceProvider (e.g., customer's bank) , and the BigBank. BigBank is the name of a financial institution, which provides funds transfer service to either its customers or the service providers.

• The customer is always the consumer of the funds transfer service; BigBank is always a provider; the serviceProvider is a provider to customers, and a consumer to the BigBank. All messages contain complete contact information for both consumer and provider along with a date sent. Contact information includes items such as name, address, phone number, and email. Basically, each message will include the contact information of the sender (consumer) and the recipient (provider).
• Messages travel between consumer and provider. In our scenario, the relationships are as below.
  customer <----> serviceProvider <----> BigBank
  
• Providers transfer money from one account to another. Each account has the following information: accountId, bankInfo, type of the account (Deposit, Card, or Loan), balance, transfertoInfo (min, max), transferfromInfo (min, max); where
  • bankInfo has bankId, bankname, country code, country name, branchId, branchName;
  • balance is a currency amount (curAmount). The curAmount has amount, currency code (ISO currency codes), and an optional currencyRate field if the currency code of the the origin account is different than the destination account,
  • transfertoInfo has the minimum and maximum currency amount that can be transfered to this account, and transferfromInfo has the minimum and maximum currency amount that can be transfered from this account.

The messages to be encoded are:

• ExRateInquiry (Exchange Rate Inquiry): A consumer (customer or the serviceProvider) asks for the fee of fund transfer service; the message should include customer identifier, the origin account (accountFrom), the destination account (accountTo), due date of the transaction, and amount as curAmount that is quoted.
• ExRateSettlement (Exchange Rate Settlement): The provider (BigBank or the serviceProvider) submits the information about the fee of any number of exchange rate transfer; the message includes references to ExRateInquiry messages, fee type (Forex, Late, Transaction, Interchange), amount of the fee as curAmount, the amount that is quoted as curAmount (the currencyRate field of the curAmount should be filled by the provider if the currency codes of the origin and destination accounts are different) for each referenced ExRateInquiry. Each message should also include an expiration date, maximum and minimum fees that can be charged by the provider per settlement. One settlement can be used by many fund transfer requests.
• FundTransfer: A consumer requests to transfer money from one account to another; the message should include a session identifier, customer identifier, AccountFrom, AccountTo, status of the transfer (e.g., delivered to BigBank, authorized by BigBank, pending by the customer`s bank, pending by the BigBank), due date, amount that is to be transfered as curAmount, delivery method (default is channel) and a reference to a ExRateSettlement.

Notes

In this assignment, you are going to give each schema a different targetNamespace. With the below design, you can define common types such as Account and CurAmount in Inquiry.xsd and reference them later in Settlement.xsd.

Inquiry.xsd

Settlement.xsd

Settlement.xml (conforming to the multiple targetNamespaces)

Deliverables

• Submit an XML schema for the ExRateInquiry (Inquiry.xsd), and ExRateSettlement (Settlement.xsd) message types. You do not need to submit XML schema for FundTransfer message type since it is trivial if you can encode the first two message types
• Submit an example xml file that instantiates each schema, i.e., Inquiry.xml and Settlement.xml, respectively.
