Transactions may be collected and processed as in batch processing. Transactions will be collected and later updated as a batch when it is convenient or economical to process them. Historically, this was the most common method as the information technology did not yet exist to allow real-time processing.
Cost–benefit analysis (CBA), sometimes also called benefit–cost analysis, is a systematic approach to estimating the strengths and weaknesses of alternatives.It is used to determine options which provide the best approach to achieving benefits while preserving savings in, for example, transactions, activities, and functional business requirements.

For example, transaction A may access portion X of the database, and transaction B may access portion Y of the database. If at that point, transaction A then tries to access portion Y of the database while transaction B tries to access portion X, a deadlock occurs, and neither transaction can move forward. Transaction-processing systems are ...
Transactional model, generally speaking, refers to a model in which interactions in two directions are considered together, for example from one person to another and back, or from one subsystem to another and back. Specifically, the term "transactional model" may refer, in biology and psychology, to the: Transactional model of stress and coping
Modelling biological systems is a significant task of systems biology and mathematical biology. [a] Computational systems biology [b] [1] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems.
Transactions are often executed concurrently (e.g., multiple transactions reading and writing to a table at the same time). Isolation ensures that concurrent execution of transactions leaves the database in the same state that would have been obtained if the transactions were executed sequentially.
Ecology deals with the energy and matter transactions of life and the Earth, and the human economy is by definition contained within this system. Ecological economists argue that neoclassical economics has ignored the environment, at best considering it to be a subset of the human economy.
The letter of intent generally does not bind the parties to commit to a transaction, but may bind the parties to confidentiality and exclusivity obligations so that the transaction can be considered through a due diligence process involving lawyers, accountants, tax advisors, and other professionals, as well as business people from both sides.
