Performance is a measure of the results achieved. Performance efficiency is the ratio between effort expended and results achieved. The difference between current performance and the theoretical performance limit is the performance improvement zone. Another way to think of performance improvement is to see it as improvement in four potential areas:
Isolation is typically enforced at the database level. However, various client-side systems can also be used. It can be controlled in application frameworks or runtime containers such as J2EE Entity Beans [2] On older systems, it may be implemented systemically (by the application developers), for example through the use of temporary tables.
The objective of Focused Improvement is to assure that the equipment maintains a peak performance all the time. "The fact is machines do virtually 100 percent of the product manufacturing work. The only thing we people do, whether we’re operators, technicians, engineers, or managers, is to tend to the needs of the machines in one way or another.

Quality Improvement can be distinguished from Quality Control in that Quality Improvement is the purposeful change of a process to improve the reliability of achieving an outcome. Quality Control is the ongoing effort to maintain the integrity of a process to maintain the reliability of achieving an outcome.
Feedback: The core principle of continual process improvement is the (self) reflection of processes; Efficiency: The purpose of continual improvement process is the identification, reduction, and elimination of suboptimal processes; Evolution: The emphasis of continual improvement process is on incremental, continual steps rather than giant leaps
a part that does not benefit from the improvement of the resources of the system; a part that benefits from the improvement of the resources of the system. An example is a computer program that processes files. A part of that program may scan the directory of the disk and create a list of files internally in memory.
In databases, and transaction processing (transaction management), snapshot isolation is a guarantee that all reads made in a transaction will see a consistent snapshot of the database (in practice it reads the last committed values that existed at the time it started), and the transaction itself will successfully commit only if no updates it has made conflict with any concurrent updates made ...
