If the order in time between certain operations is not determined by the system, then a partial order is used. Examples of such operations are requesting a read operation, reading, writing, aborting, committing, requesting a lock, locking, etc. Often, only a subset of the transaction operation types are included in a schedule.
An execution model covers things such as what is an indivisible unit of work, and what are the constraints on the order in which those units of work may take place. For example, the addition operation is an indivisible unit of work in many languages, and in sequential languages such units of work are constrained to take place one after the other.
The order of operations, that is, the order in which the operations in an expression are usually performed, results from a convention adopted throughout mathematics, science, technology and many computer programming languages. It is summarized as: [2] [5] Parentheses; Exponentiation; Multiplication and division; Addition and subtraction
Causality preservation: ensures the execution order of causally dependent operations be the same as their natural cause-effect order during the process of collaboration. The causal relationship between two operations is defined formally by Lamport's "happened-before" relation. When two operations are not causally dependent, they are concurrent.
The final suspect pleaded guilty in February of 1993 to hindering prosecution and received a sentence of 1 ½ to 4 ½ years in prison. He was also released to parole in 1996 and ultimately ...
Sequential consistency is a consistency model used in the domain of concurrent computing (e.g. in distributed shared memory, distributed transactions, etc.).. It is the property that "... the result of any execution is the same as if the operations of all the processors were executed in some sequential order, and the operations of each individual processor appear in this sequence in the order ...
