compare Programmatic and Declarative Transaction Management:

Programmatic Vs Declarative Transaction Management

• Programmatic transaction management is good only if you have a small number of transactional operations. (Most of the times, this is not the case.)
• Transaction name can be explicitly set only using Programmatic transaction management.
• Programmatic transaction management should be used when you want explicit control over managing transactions.
• On the other hand, if your application has numerous transactional operations, declarative transaction management is worthwhile.
• Declarative Transaction management keeps transaction management out of businesslogic,and is not difficult to configure.
