This is currently problematic as data is scattered over heterogeneous, mostly file-based legacy databases, the data is erroneous, incomplete, and inconsistent in representation and content. The authors have developed a methodology, including metadata specification data transformation and software architecture, that supports data analysis and preparation for building a data warehouse using object-oriented database technology. With this methodology the system ReLiBase has been realized, that allows querying and visualization of the drug-design related data from heterogeneous resources.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122626563","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}

We show how their limitations can be overcome, while exploiting their strengths, in the SCOPES (Semantic Coordinator Over Parallel Exploration Spaces) architecture. SCOPES (A. Ouksel and C.

Since the components in a federation are autonomous, their data may be updated asynchronously, viz., modifications to a real world entity may be captured in different databases at different times; the authors term this effect update heterogeneity. Existing approaches largely base data instance similarity identification only on current attribute/property values; in the face of update heterogeneity, this is inadequate. They present an approach to address the problem of update heterogeneity in the federated databases context. They employ a probabilistic model, which utilizes historical database update information to estimate the degree of similarity between candidate data instances from different database components. They employ transaction history (log) information to this end, which is typically already available in the component database systems. They have experimentally implemented and tested this approach within the context of a prototype experimental federated databases system, FeXpress.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132912337","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 role-set approach presents the answer to a query as a set of relations where the distinct intersections between the relations correspond to the various roles played by an entity. The authors show how the basic role-based approach can be extended in the absence of information about the multidatabase keys (global IDs). They propose a strategy based on ranked role-sets that makes use of a semantic integration procedure based on neural networks to determine candidate global IDs. The data integration and query processing steps then produce a number of role-sets, ranked by the similarity of the candidate IDs.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123028025","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 ability of a user of a database participating in a federated system to retrieve information from the other database systems will be greatly enhanced by acquiring a better comprehension of these systems. The authors are trying to develop both a theoretical paradigm and a methodology to analyze existing large schemas. Their approach to achieve comprehension is based on combining two concepts: informational thinning (i.e. concentration on the specialization hierarchy of the schema) and partitioning. They present a new technique for modeling which is called disciplined modeling. Based on the rules of disciplined modeling we develop a theoretical paradigm to support the existence of a meaningful forest hierarchy within the specialization hierarchy. Such a hierarchy functions as a skeleton of the schema and supports comprehension and partitioning efforts.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114665869","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}

Thus, we provide a suite of options with protocols for various environments with specific system capabilities and integrity requirements.","PeriodicalId":314823,"journal":{"name":"Proceedings First IFCIS International Conference on Cooperative Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-06-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128348092","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}
