The problem is to synchronize concurrent interactions so that each reads consistent data from the data base, writes consistent data, and is ultimately processed to completion. In a distributed data base this problem is exacerbated because a concurrency control mechanism at one site cannot instantaneously know about interactions at other sites. No fewer than 30 papers on this topic have appeared to date. Our purpose is to survey this literature, concentrating on three approaches—locking, majority consensus, and SDD-1 protocols—which together subsume the bulk of the literature. **","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122276096","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}

In particular, there has been a drastic growth of on-line systems for business-oriented applications. We see a shift of interest in computers from their mere computational power to their data management capability, especially in these applications. User demand for the growth of on-line storage capacity in this environment is said to be much larger than the demand for the growth of computational power. We expect the business-oriented computer system to become an information utility in the future.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134206957","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}

Present-day database management systems are designed primarily for efficient storage, retrieval and manipulation of alphanumeric data. Until very recently, little attention has been paid to the storage, retrieval and manipulation of non-alphanumeric information such as digitized images which require a large amount of storage even for pictures of average complexity. With the growing list of new applications in picture processing, such as geographic data processing, demographic data processing, computed tomography, whole-body scanner, earth resources survey satellite (LANDSAT) image processing, regional economic and health data processing, cartographic and mapping applications, etc., the problem of efficient, economical storage, retrieval and manipulation of vast amounts of pictorial information becomes more important and requires careful considerations.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134319319","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}

Such a simplistic approach is not accurate enough for calculating delays when designing high-performance large systems using high-speed, non-saturating circuits such as HCML (Honeywell’s Current Mode Logic). There are several reasons: • The clock (cycle) time is considerably faster for a high speed machine, hence the calculations must be very accurate in order to meet performance goals. • The loading on the driving gate varies with the number of driven gates, hence affecting the rise time of the line (interconnect) voltage. • The geometry of the interconnect (branch points, connectors, various media impedances) has an effect on signal propagation with high-speed edges. • Media delay is a significant percentage of path delay as ICs become faster.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116093559","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}

In a reasonably large class of problems one can devise and evaluate algorithms with respect to measures independent of the storage and structuring of data. But when the question is the investigation of a suitable data structure for retrieval of a specific kind, algorithms and their measures depend heavily on the proper file design. This paper addresses both file design and algorithm design when searches are to be made in a data base for queries of speciaJ type.

Typically, these systems involve quite a few hierarchical microprocessors-they perform fairly sophisticated control functions, and must comply with stringent reliability and availability demands. Though the distribution of functions significantly reduces the complexity of some of the technical problems usually encountered in such systems, the volume of software to be developed remains large, and system tests are still a problem. Furthermore, the development systems offered on the market by microprocessor manufacturers or independent vendors are very well adapted to the development of small applications which involve a unique microprocessor and a limited volume of code, but they are insufficient for the development of large systems. The system builder engaged in distributed system development will, therefore, have problems to solve, until the ideal support software and hardware are made available on the market.","PeriodicalId":341008,"journal":{"name":"1979 International Workshop on Managing Requirements Knowledge (MARK)","volume":"2016 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1899-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126005968","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}
