What’s a transaction?. Transaction: a finite sequence of machine instructions, executed by a single process, that satisfies the following:. The study of human behaviour is very complex and complicated concept.. It is affected by the psychological factors such as perception, learning, peronality and motivation.. In addition to these factors, individual behaviour affects and affected by the behaviour of others. . Sue Madden . . Manager/Principal . Officer, . Foster . Care & . Adoptions, . Anglicare Sydney.
