The WPBS signature processor is based on a transposed file organization and is optimal in the sense that the smallest possible amount of data is read. As such, it performs much faster than the word-serial, bit-parallel (WSBP) signature processor proposed in the literature. In addition, it can easily accommodate signatures of different lengths in the same signature store. This feature is important in utilizing the signature store efficiently but difficult to implement with a WSBP architecture. We also discuss the implementation of the processor with magnetic bubble memory.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115133270","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}

It appears to the user to be a distributed DBMS, although many of the DBMS functions are actually provided by the underlying DBMS. It currently runs above three relational DBMSs, the IDM database machine connected to a VAX, Ingres on two Suns, and Mistress on a third Sun. One of the key components of the AIDA system is Mermaid which provides query optimization, networking, and system control. Mermaid required research into query optimization where the costs of operations on the different processors and DBMSs is variable, the network cost is variable, and capabilities of the different DBMSs is variable. We extended existing distributed query optimization algorithms to support replicated and fragmented relations. In this paper, we discuss our experiences with the development and testing of the Mermaid system and with the integration of Mermaid with the AIDA translator. We discuss the types of commands, the system controller, and our experiences with distributed debugging. Then we give the results of our initial performance tests.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"17 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120809153","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}

Using a simulation model, we study the problem for a DDBS in various application and system environments. In particular, we have considered: the preclaim, and the claim-as-needed locking policies; three different granule placements; two different transaction sizes; and two different communication delays. Conclusions concerning the optimal choices of granularity and the degree of multiprogramming in different environments are then drawn to provide guidelines in achieving good performance in a DDBS.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127361213","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 management system performs a unit resolution with setting using relational operations for the extensional databases.

It discusses how a data management system which manages abstract data types provides a framework for integrating a CAD environment by providing a single mechanism to manage data, programs, and the manipulation of the data with the programs. It also shows how two forms of abstraction, aggregation and generalization, can be used to model hierarchies of parts and components, and multiple design alternatives, respectively. These abstractions are then used to model the geometrical and topological data required to describe three-dimensional mechanical parts.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129431813","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 tree-locking protocol assumes the existence of a partial order defined over all of the objects in a database. Requiring all transactions to be tree-locked with respect to this single partial order limits the degree of concurrency obtainable in a database system by increasing the potential for conflict between transactions. In this paper we define a new locking protocol that is derived from the tree-locking protocol, but allows a changing set of partial orders to be defined over the objects in a database. We call this protocol dynamic tree-locking.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1986-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114350316","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}
