The paper investigates practical approaches to enforcing referential integrity, one of the most important classes of constraints. Referential integrity is important in its own right and also provides a good starting point for studying more general classes of constraints. The semantics of referential integrity are relatively well known and understood, yet they have much in common with more general classes of constraints. The paper considers what enforcement mechanisms can be used in the context of the transaction models or interaction models which are widely found in practice today: the queued message model, the remote procedure call model, the distributed transaction model, and the local transaction dialog model.<<ETX>>","PeriodicalId":302564,"journal":{"name":"Proceedings RIDE-IMS `93: Third International Workshop on Research Issues in Data Engineering: Interoperability in Multidatabase Systems","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122008599","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 system uses agents to implement different types of transaction managers; each transaction manager implements a transaction model tailored for a specific application.

Agents, through the use of system level triggers on shared control information, support extended transaction models. Applications are presented with a choice of concurrency control and commit protocols to support transaction management. The current prototype is running as a data management backbone for a multimedia communication system supporting 160 users.<<ETX>>","PeriodicalId":302564,"journal":{"name":"Proceedings RIDE-IMS `93: Third International Workshop on Research Issues in Data Engineering: Interoperability in Multidatabase Systems","volume":"5 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120915508","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}

Besides transformations on the semantics level conversions on the data representation and communication protocol level have to be done. The authors present the Remote Cooperation System RCS which provides client/server communication procedures independent of hardware and operating system aspects. Thus, the configuration of a system may change without affecting the participating databases and application tools. The RCS allows for asynchronous service invocation, thus enabling the simultaneous querying of several databases by one application. Furthermore, it supports multi-tasking of server processes and the element-wise transfer of results. Monitoring tools allow the assessment of several choices in system configuration and access algorithms embodied in the application processes.<<ETX>>","PeriodicalId":302564,"journal":{"name":"Proceedings RIDE-IMS `93: Third International Workshop on Research Issues in Data Engineering: Interoperability in Multidatabase Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116904432","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}

A relay is a stream of bitransactions (binary transactions) propagating updates like a wave. Each bitransaction is atomic while the global process is asynchronous in the sense that a bitransaction starts as soon as the previous one commits. The goal is to extend relay race for supporting temporal consistency constraints. Temporal consistency is treated through a couple of consistency rules; one simply checks the consistency of a copy and does not depend on any consistency predicate; the other one implements the protocol for restoring the consistency of a copy whenever the associated consistency predicate becomes true.<<ETX>>","PeriodicalId":302564,"journal":{"name":"Proceedings RIDE-IMS `93: Third International Workshop on Research Issues in Data Engineering: Interoperability in Multidatabase Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129035865","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}

Many researchers perceive the difficulty to be the lack of reliable cost estimates for autonomous component databases. Consequently, some have suggested that this problem degenerates to a distributed query optimization (DQO) problem once cost model coefficients for component databases are found. The authors argue that autonomy and heterogeneity of component databases give rise to a number of issues which make MQO a distinct problem from DQO. Consequently, existing solutions for DQO need to be re-evaluated in the light of these issues. The design of a multidatabase query optimizer, which accounts for the issues highlighted, is discussed. This provides a framework within which further research in MQO can be carried out.<<ETX>>","PeriodicalId":302564,"journal":{"name":"Proceedings RIDE-IMS `93: Third International Workshop on Research Issues in Data Engineering: Interoperability in Multidatabase Systems","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127475203","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}
