Transaction processing is an established technique for the concurrent and fault­ tolerant access of persistent data. While this technique has been successful in standard database systems, factors such as time-critical applications, emerg­ ing technologies, and a re-examination of existing systems suggest that the performance, functionality and applicability of transactions may be substan­ tially enhanced if temporal considerations are taken into account. That is, transactions should not only execute in a "legal" (i.e., logically correct) man­ ner, but they should meet certain constraints with regard to their invocation and completion times. Typically, these logical and temporal constraints are application-dependent, and we address some fundamental issues for the man­ agement of transactions in the presence of such constraints. Our model for transaction-processing is based on extensions to established mod­ els, and we briefly outline how logical and temporal constraints may be ex­ pressed in it. For scheduling the transactions, we describe how legal schedules differ from one another in terms of meeting the temporal constraints. Exist­ ing scheduling mechanisms do not differentiate among legal schedules, and are thereby inadequate with regard to meeting temporal constraints. This provides the basis for seeking scheduling strategies that attempt to meet the temporal constraints while continuing to produce legal schedules.

This reverse osmosis system is a highly efficient, 4 Stage filtration, dual filter, compact, under-sink system with a smart stainless-steel faucet included. With a high filtration capacity of 600 Gal. per day, the tankless RO water filter system produces instant pure water to the provided faucet, filling a cup of water within 18-seconds, It installs conveniently under the sink in an upright position (17.1 in. x 5.4 in. x 15.9 in.), saving over 70% more under-sink space than an ordinary RO system. The tankless design minimizes the chance of bacterial growth and wastewater, this system filters as it dispenses and does not store any filtered water, as opposed to traditional systems that store the filtered water in a tank, which risks the chances of bacterial growth. This RO system has a drain ratio of 2:1 which allows it to save 600% more water. Quiet while running, it is an efficient and environmentally friendly system. MRO003 is certified by IAPMO Rand T against NSF/ANSI 58 for material safety, structural integrity and TDS reduction, NSF/ANSI 372 standard for Lead-Free compliance.
