Work ows are activities that involve the coordinated execution of multiple tasks performed by different processing entities They exist not just in computer applications, but also in almost all organizational activities With the growth of networks, and the existence of multiple autonomous database systems, work ows provide a convenient way of carrying out tasks that involve multiple systems Although the usual ACID transactional requirements are too strong or are unimplementable for such work ow applications, work ows must satisfy a limited set of transactional properties that guarantee that a process is not left in an inconsistent state Transaction-processing monitors were initially developed as multithreaded servers that could service large numbers of terminals from a single process They have since evolved, and today they provide the infrastructure for building and administering complex transaction-processing systems that have a large number of clients and multiple servers They provide services such as durable queueing of client requests and server responses, routing of client messages to servers, persistent messaging, load balancing, and coordination of two-phase commit when transactions access multiple servers Large main memories are exploited in certain systems to achieve high system throughput In such systems, logging is a bottleneck Under the group-commit concept, the number of outputs to stable storage can be reduced, thus releasing this bottleneck The ef cient management of long-duration interactive transactions is more complex, because of the long-duration waits, and because of the possibility of aborts Since the concurrency-control techniques used in 16 use waits, aborts, or both, alternative techniques must be considered These techniques must ensure correctness without requiring serializability A long-duration transaction is represented as a nested transaction with atomic database operations at the lowest level If a transaction fails, only active shortduration transactions abort Active long-duration transactions resume once java qr code reader zxing Creating and Reading QR Codes with Node.js | www ...
