Data Access and Transactions

Transactional Components

Applications that access databases can be built two ways: Business logic can reside in a particular database, or it can be packaged into components. The advantage of using components is that business rules can be generalized to work with any database, and can be reused in multiple applications.

When business logic is segregated into components that work in multiple scenarios, the components become building blocks for applications. The same components can be used for both network and Web-based applications. Reusing components speeds development time and lowers costs.
