Querying a Bioinformatic Data Sources Registry with Concept Lattices [chapter]

Nizar Messai, Marie-Dominique Devignes, Amedeo Napoli, Malika Smaïl-Tabbone
2005 Lecture Notes in Computer Science  
In this paper we present an approach based on formal concept analysis to classify and search relevant bioinformatic data sources for a given user query.  ...  The concept built from a given user query is then merged into the concept lattice.  ...  Acknowledgments We would like to thank Shazia Osman for her contribution to the conception of the BioRegistry model, its construction and indexation of the data sources it contains.  ...

An object-oriented approach to distributed data management

M.P. Papazoglou, L. Marinos
1990 Journal of Systems and Software  
An object-oriented framework is presented for the development of an integrated environment in which a collection of independent heterogeneous data repositories are merged to form a loosely coupled data  ...  This framework promotes interoperability and extensibility of heterogeneous data managers as it facilitates the development of well-defined interfaces to a wide variety of existing information sources.  ...  By advocating a single unifying data model, we are offering a concise architectural framework for heterogeneous systems that can evolve into equivalent homogeneous systems.  ...

A multi-granularity locking model for concurrency control in object-oriented database systems

Suh-Yin Lee, Ruey-Long Liou
1996 IEEE Transactions on Knowledge and Data Engineering  
A dual queue scheme for efficient scheduling of lock requests is developed. The model consists of a rich set of lock modes, a compatibility matrix, and a locking protocol.  ...  A locking model adopting a multi-granularity approach is proposed for concurrency control in object-oriented database systems.The model is motivated by a desire to provide high concurrency and low locking  ...  A formal framework for the schema evolution of ORION was presented in [ll] . The semantics of class hierarchy is what complicates schema changes and locking requirements.  ...

Description Logics for Conceptual Data Modeling [chapter]

Diego Calvanese, Maurizio Lenzerini, Daniele Nardi
1998 Logics for Databases and Information Systems  
For this purpose we use a unifying Description Logic, which incorporates all the features needed for the logical reformulation of the data models used in the various contexts.  ...  We also discuss the problem of devising reasoning procedures for the unifying formalism, and show that they provide valuable supports for several important data modeling activities.  ...  We show that these features make LOGICS FOR DATABASES AND INFORMATION SYSTEMS ALCQI powerful enough to provide a unified framework for object-oriented languages and semantic data models.  ...

Generic and Declarative Approaches to Data Quality Management [chapter]

Leopoldo Bertossi, Loreto Bravo
2013 Handbook of Data Quality  
Data quality assessment and data cleaning tasks have traditionally been addressed through procedural solutions.  ...  In the last few years we have seen the emergence of more generic solutions; and also of declarative and rule-based specifications of the intended solutions of data cleaning processes.  ...  In [36] a data cleaning framework is provided for conditional functional dependencies.  ...

The Typed Graph Model – a Supermodel for Model Management and Data Integration [article]

Fritz Laux
2021 arXiv   pre-print
It is difficult to ensure data quality for the properties and the data structure because the model does not need a schema.  ...  We prove that the model is at least equivalent in expressive power to most popular data models. Therefore, it can be used as a supermodel for model management and data integration.  ...  Torlone, ”Schema Translation between Heterogeneous 20121211/ [retrieved: 2021-12-06] Data Models in a Lattice Framework”, DS-6: Proceedings of the [24  ...

2004 Lecture Notes in Computer Science  
Ontological specifications are used for identification of mediator classes semantically relevant to a source class.  ...  The data integration systems described in [2,13] follow an approach in which the contents of the sources are described as views over the mediated schema.  ...  Semantic knowledge about the object data model, e.g., class hierarchy information, relationship between objects, as well as semantic knowledge about a particular schema and application domain are expressed  ...
