Database sharing: an efficient mechanism for supporting concurrent processes 数据库共享:一种支持并发进程的有效机制

Requisites for efficient transaction processing include (1) a multiprogramming system oriented toward maximizing throughput subject to the response-time requirement of the interactive environment, and (2) an integrated database with centralized access control. An integrated database implies the elimination of redundant data processing. Such is necessary (though not sufficient) to achieve acceptable performance in transaction processing. The necessity of an efficient, responsive multiprogramming system is, of course, obvious. But efficiency in the transaction environment necessitates certain system provisions peculiar to the environment. One of these is the provision for the shared use of data. Time-sharing systems, while they generally provide for shared procedures, do not generally provide elaborate facilities for data sharing, since users typically do not require access to files other than their own. In the transaction environment, typified by a number of users operating on a single integrated database, elaborate provisions for database sharing are required.","PeriodicalId":376661,"journal":{"name":"AFIPS National Computer Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1973-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127974934","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All of that is completely disturbed by the pretentiousness, insistence and complicatedness of computer graphics and all the allied techniques.

One important thread has been the use of an array of processors to allow a single control stream to operate simultaneously on a multiplicity of data streams; the most ambitious effort in this direction has been the ILLIAC IV project. Another important thread has been the partitioning of problems so that several control streams can operate in parallel. Often functions have been unloaded from a central processor onto various specialized processors; examples include data channels, display processors, front-end communication processors, on-line data preprocessors---in fact, I/O processors of all sorts. Similarly, dual processor systems have been used to provide load sharing and increased reliability. Still another thread has been the construction of pipeline systems in which sub-pieces of a single (generally large) processor work in parallel on successive phases of a problem. In some of these pipeline approaches the parallelism is \"hidden\" and the user considers only a single control stream.","PeriodicalId":376661,"journal":{"name":"AFIPS National Computer Conference","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1973-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117149488","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The RSEXEC creates an environment which facilitates the sharing of resources among Hosts on the ARPANET.

By sharing resources among themselves the large Hosts can provide a level of service better than any one of them could provide individually.
