For session-managed applications that use bound connections, which support complex transactions, the operations can perform simple (less powerful), fine-grained procedures and functions because the ultimate result for a client does not have to be completed in a single request. Each procedure or function executed in a series of session-managed requests can help to assemble the context of a single transaction until a single committing operation completes the transaction after this context is complete.

An example might be a transaction to assemble a bill of materials (BOM), where the transaction depends on what components are already in stock for the BOM, requiring the client to invoke different operations to complete the structure of the transaction. Once the structure is completed for any missing components, the BOM transaction can be committed using a final operation.
