The response time needed to process path and range queries on the grid file access method can be improved significantly by distributing the data pages over multiple disks. The paper explores the disk allocation methods used to allocate the data pages of grid file among a set of disks, which can be accessed in parallel. Given N disks, a perfect allocation will speed up the processing of each query by a factor of N in this environment. The authors show that no disk allocation is perfect for the set of all orthogonal range queries, even on uniformly distributed read-only data. They then introduce two families of allocation methods, namely the Linear allocation method and the Lattice allocation method, which are perfect for a large collection of interesting path queries (rows, columns, diagonals, anti-diagonals) and range queries (small rectangles), on an interesting set of data distributions. They address the issues in extending disk allocation methods to general data distributions with random updates. Finally, they provide experimental results on the performance of the proposed methods and other well known disk allocation methods on different query sets, data distributions and data set sizes.<<ETX>>","PeriodicalId":142465,"journal":{"name":"Proceedings of 1994 IEEE 10th International Conference on Data Engineering","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125572138","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}

Need to increase productivity and reduce cost have lead to reengineering and automation of operations across corporations. Some of the applications involve imaging, document processing and routing. These tasks can be effectively automated using current genre of workflow automation products. Some other applications involve tasks that can be modeled in client-server style using traditional transactions. These can be supported by distributed transaction processing/monitoring systems. Finally, there is an important class of more complicated applications that involve heterogeneous but automated tasks, with varying levels of transaction properties, and performed at heterogeneous systems. We look at three aspects of the emerging technology of transactional workflow management that aims to support such applications: Identify properties of a class of multi-system applications and the environments that can be supported by transactional workflow systems: Discuss how a transactional workflow management system is different from, but \"builds upon\" the current transaction processing and workflow automation technologies: Discuss some of the relevant database research as well as software system and application prototyping experiences, especially those related to the extended/relaxed transaction models. Much of the discussion is based on our study of some real (mostly telecommunications) applications, and research and prototyping done at Bellcore in collaboration with U. of Houston and MCC's Carnot project.<<ETX>>","PeriodicalId":142465,"journal":{"name":"Proceedings of 1994 IEEE 10th International Conference on Data Engineering","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133281295","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 non-homogeneous database access model described in this paper allows multiple transaction classes with different access patterns to the database regions. The performance of the system from the viewpoint of lock contention is analyzed in the context of the standard two-phase locking concurrency control method with the general waiting policy. The approximate analysis is based on mean values of parameters and derives expressions for the probability of lock conflict (usually leading to transaction blocking) and the mean blocking time. The latter requires estimating the distribution of the effective wait-depth encountered by blocked transactions and the mean waiting time associated with different blocking levels. The accuracy of the analysis is validated against simulation results and also shown to be more accurate than analytic solutions considering only two levels of transaction blocking. Previously proposed metrics for load control have limited applicability for the model under consideration.<<ETX>>","PeriodicalId":142465,"journal":{"name":"Proceedings of 1994 IEEE 10th International Conference on Data Engineering","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124153335","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}
