Distributed Transaction Processing
2019The concept of a transaction is used in database systems as a basic unit of consistent and reliable computing. Thus, queries are executed as transactions once their execution strategies are determined and they are translated into primitive database operations.

Distributed logging for transaction processing
Proceedings of the 1987 ACM SIGMOD international conference on Management of data - SIGMOD '87, 1987Increased interest in using workstations and small processors for distributed transaction processing raises the question of how to implement the logs needed for transaction recovery. Although logs can be implemented with data written to duplexed disks on each processing node, this paper argues there are advantages if log data is written to

A traditional presupposition in science is that nature ultimately is simple and comprehensible. Accordingly, ‘theory reduction’ is a primary goal in much of ecosystems science – the belief, for example, that ecosystem development can be described by a single covering principle.

Cryptocurrency Transaction Processing
2020In a cryptocurrency network such as Bitcoin or Helium, the fundamental unit of interaction is a transaction where value is transferred from one entity to another. In this type of network, the blockchain is an immutable, distributed ledger of all of the transactions that have transpired on the network.

Transaction technology for process modelling
1995Process Modelling (PM) is a software engineering discipline that aims at supporting the development of large and complex software systems. Therefore, PM focusses on study, de nition, enaction, and possibly improvement of software process models. Traditional transaction management (TM) protects data against unexpected system failures, con icts or ...

Transaction processing primitives and CSP
IBM Journal of Research and Development, 1987Several primitives for transaction processing systems are developed using the notations of Communicating Sequential Processes. The approach taken is to capture each requirement separately, in the simplest possible context: The specification is then the conjunction of all these requirements.

Transaction Processing Systems [PDF]
ACID properties A transaction is characterized by four properties referred to as the ACID properties: atomicity, consistency, isolation, and durability. database update The real effect of a transaction; it takes one of three forms: add, change, and delete.

This is a code-intensive chapter. In the previous two chapters, we have examined the theory of cryptocurrency transactions and seen how the merkle root can be used to verify that the transactions in a block have not been tampered with. In this chapter, we are going to put this theoretical knowledge into practice by implementing Python code for ...

A Comparison of Query Processing Architectures and Transaction Processing
International Journal of Scientific Research, 2012A wide range of database applications manage time-varying data, and it is well known that querying and correctly updating time-varying data is difficult and error-prone when using standard SQL. Temporal exten- sions of SQL offer substantial benefits over SQL when managing time-varying data.

Adaptive Hybrid Transaction Processing with Hardware Transaction Memory
2019 IEEE 21st International Conference on High Performance Computing and Communications; IEEE 17th International Conference on Smart City; IEEE 5th International Conference on Data Science and Systems (HPCC/SmartCity/DSS), 2019Many performance-sensitive software systems gain benefit from the availability of advanced hardware features, and many research works have been transited to engineering reality. For instance, restricted hardware transaction memory (HTM), a hardware feature providing hardware atomicity and isolation guarantees for transactional execution, has gained ...
