Composite Transactions

A composite transaction in Open Cloud MDM is defined as an aggregation of multiple single transactions. These transactions are executed as a part of a larger, cohesive operation. This approach is beneficial for handling complex business processes where several discrete actions need to be performed in a sequence or in tandem.

Methods for Creating Composite Transactions:

  1. Using Customized Business Proxies:
    • In this method, composite transactions are created through the use of customized business proxies.
    • Business proxies in Open Cloud MDM are designed to act as intermediaries between the client requests and the core MDM functionalities.
    • By customizing these proxies, you can define a sequence of transactions that are triggered in response to a single request. This customization allows for tailored transaction flows that align closely with specific business processes and logic.
  2. Using XML:
    • Alternatively, composite transactions can be constructed using XML.
    • This method involves defining the sequence of transactions in an XML format, where each transaction and its parameters are specified.
    • The XML composite transaction framework within Open Cloud MDM then interprets this XML script and executes the defined transactions in the specified order.
    • Using XML provides a flexible, declarative way of defining complex transaction sequences, allowing for easy adjustments and updates to the transaction flow without needing to modify the underlying application code.

Benefits of Composite Transactions:

  • Composite transactions streamline complex processes by consolidating multiple steps into a single operation, enhancing both efficiency and reliability.
  • They ensure data integrity, as the entire set of transactions is typically treated as a single unit of work. This means that if one part of the composite transaction fails, the entire operation can be rolled back to maintain data consistency.
  • This feature is particularly advantageous in scenarios where multiple data entities need to be updated in a synchronized manner to reflect a coherent state across the MDM system.

Composite transactions in Open Cloud MDM offer a versatile and efficient mechanism for handling complex data manipulation tasks. Whether through customized business proxies or XML, these transactions enable sophisticated data processing workflows, crucial for advanced MDM solutions.
