The system is based on a generalized model of access paths and is applicable to most access paths for searching a database system. The study brings to light many subtle but important parameters which can have a significant effect on the performance of the access paths, and which, then, must be taken into consideration in the selection of such paths.","PeriodicalId":385279,"journal":{"name":"Proceedings of the 1978 ACM SIGMOD international conference on management of data","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1978-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133251733","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}
