    • A distributed transaction processing system is disclosed in which a process automation application receives a transaction request from a requesting application. In response to the request, the process automation application obtains a transaction definition for the transaction requested by the requesting application. This transaction definition comprises a plurality of operation definitions, which indicate a plurality of operations constituting the requested transaction. For each of the operation definitions in the transaction definition, the process automation application produces an operation request. These operation requests are sent to one or more service applications, and one or more responses are received by the process automation application after the operations are performed by the service applications. Based on the responses, the process automation application produces a transaction response, which is sent to the requesting application. In this manner, the requested transaction is completed.
    • 公开了一种分布式事务处理系统,其中过程自动化应用程序从请求应用程序接收事务请求。 响应于该请求,过程自动化应用程序获得请求应用程序请求的事务的事务定义。 该交易定义包括多个操作定义,其指示构成所请求的交易的多个操作。 对于事务定义中的每个操作定义,过程自动化应用程序产生操作请​​求。 这些操作请求被发送到一个或多个服务应用,并且在由服务应用执行操作之后,过程自动化应用接收一个或多个响应。 基于响应,过程自动化应用程序产生事务响应,该事务响应被发送到请求应用程序。 以这种方式,请求的交易完成。

    • A process automation application, referred to as a commerce exchange server, for sending transaction messages between application programs uses a transaction definition data structure for specifying the component operations and processing logic that comprise the transaction. The data structure specifies one or more operations that constitute the transaction, instructions for producing the input data needed for each operation, and conditional logic for specifying constraints on the sequence of operation execution. The conditional logic may include one or more expressions, ranging from simple to complex, including variables, math operations and functions, that are evaluated using the inputs or outputs of one or more prior operations to determine execution order of subsequent operations. The transaction definition data structure may also provide for broadcast operations and for conditioning the success of their execution. In an illustrated implementation, the transaction definition data structure is an XML (Extensible Markup Language) document in the form of a directed acyclic graph (DAG). A transaction service architecture provides for storing transaction definitions that define specific types or categories of transactions in a transaction database, and for matching a transaction definition to a transaction definition identifier from a requesting application. The transaction service then builds a transaction instance DAG to perform the transaction, produces the messages needed for performing the transaction, and manages the message flow to and from the service applications that perform the constituent operations of the transaction.
    • 被称为商业交换服务器的过程自动化应用程序用于在应用程序之间发送交易消息使用事务定义数据结构来指定构成事务的组件操作和处理逻辑。 数据结构指定构成事务的一个或多个操作,用于产生每个操作所需的输入数据的指令,以及用于指定对操作执行顺序的约束的条件逻辑。 条件逻辑可以包括从简单到复杂的一个或多个表达式,包括变量,数学运算和函数,其使用一个或多个先前操作的输入或输出进行评估,以确定后续操作的执行顺序。 事务定义数据结构还可以提供广播操作并且用于调节其执行的成功。 在所示实现中,事务定义数据结构是以有向无环图(DAG)的形式的XML(可扩展标记语言)文档。 事务服务架构提供用于存储在事务数据库中定义事务的特定类型或类别的事务定义,以及用于将事务定义与请求应用程序的事务定义标识符进行匹配。 然后,事务服务构建事务实例DAG以执行事务,产生执行事务所需的消息,并管理到执行事务的组成操作的服务应用程序的消息流。
