Several data models have emerged, but their comparative value is unclear. We think that an appraisal is only possible if the nature — and not only the goal — of requirements analysis is clearly perceived. We investigate this point and emphasise that requirements analysis is an activity of acquiring real-world knowledge, thereby forming a theory in which objectives can be stated and a solution specified. A suited language should thus restrict as little as possible the freedom of expression when describing some part of the world. A number of requirements are derived from this statement, such as the possibility to describe individual objects, as well as groups of objects, to explicitly refer to a global continuous time, to handle undefinedness, to allow simultaneous events, etc. When assessing the various existing data models with respect to these requirements, the entity-relationship model is found a suitable basis, but still lacking essential features. We extend it in a model called ERAE (entity, relationship, attribute, event), which is presented informally and illustrated on examples.","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":"114377461","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}

Data stored in these networks need to be integrated and shared by the network users. It is important to have a query processing strategy in this type of network that can take advantage of the diverse functional capabilities of the component systems and the parallel processing potential of the network. In this paper, we present a query processing strategy which combines three known techniques: 1) query decomposition, 2) pipelined and data-flow processing of queries, and 3) intermediate result sharing among concurrent queries. The strategies for controlling and managing query and data pipelines are presented. Algorithms for the pipelined execution of the relational join operation are also described. Selected results of the evaluation of the query processing strategy, pipeline control strategies, and parallel algorithms are presented.","PeriodicalId":415748,"journal":{"name":"1986 IEEE Second International Conference on Data Engineering","volume":"102 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":"115034293","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}
