Scenario: Composing Work from Multiple Components Under the Same Transaction

[This product will work only on Windows NT 4.0 versions and earlier. For Windows 2000 and later, see COM+ (Component Services).]

For this scenario, you will add new functionality that allows you to transfer money between two accounts. To implement this, you add a new component, MoveMoney. MoveMoney creates Account and then calls it once for a credit or debit, or twice for a transfer, as shown here.

Because either MoveMoney or Account could fail at any point, all database updates need to be in the same transaction to ensure that the database remains consistent. To do this, you configure the MoveMoney and Account components in the Microsoft Transaction Server Explorer to require a transaction. Transaction Server ensures that all their objects' work is automatically done in the same transaction.
