Conceptual Design of an XML FACT Repository for Dispersed XML Document Warehouses and XML Marts

R. Rajugan, E. Chang, T.S. Dillon
2005 The Fifth International Conference on Computer and Information Technology (CIT'05)  
In this paper, we address such an issue, where we propose a view-driven approach for modeling and designing of a Global XML FACT (GxFACT) repository under the MDA initiatives.  ...  This presents an interesting challenge to investigate models, frameworks and techniques for organizing and analyzing such voluminous, yet distributed XML documents for business intelligence in the form  ...  The e-Sol solution includes a standalone and distributed Warehouse Management System (WMS/e-WMS), and a Logistics Management System (LMS/e-LMS) on an integrated e-Business framework called e-Hub [51]  ...

SeGA: A Mediator for Artifact-Centric Business Processes [chapter]

Yutian Sun, Wei Xu, Jianwen Su, Jian Yang
2012 Lecture Notes in Computer Science  
Business processes (BPs) can be designed using a variety of modeling languages and executed in different systems.  ...  We demonstrate that SeGA provides a simple yet general framework for runtime querying and monitoring BP executions cross different BP management systems.  ...  Such systems are inadequate for business collaboration that involves different independently executing processes, and under different business process models.  ...

Propagating Integrity Information among Interrelated Databases [chapter]

A. Rosenthal, E. Sciore
1998 Integrity and Internal Control in Information Systems  
It appears feasible to create a system that drastically reduces the skill and labor required for propagating metadata and events between the tiers.  ...  Unfortunately, an assertion about some granule in the sources (a table, column, or cell) is often meaningless to view users, and vice versa.  ...  For downward propagation, constraint predicates on view tables can be seen as queries, so query processors can re-express them on the source tables.  ...

A Review Paper on Different Approaches for Query Optimization using Schema Object base View

Dhaval Patel, Pratik Patel
2015 International Journal of Computer Applications  
In this paper, the different techniques is given for optimizing query using schema based and materialized views in data warehouse namely-view adaptation & synchronization, view selection and view maintenance  ...  Query optimization is a purpose of many relational database management systems.  ...  The first approach is for materialized view selection, the essential constraints for materialize view selection are: query frequency, query processing time and storage space [8] .  ...

2005 Lecture Notes in Computer Science  
We focus on conceptual and schema view definitions, view constraints, and the conceptual query operators.  ...  In this paper, we use XML view as a case in point and present a three-layered view model with illustrated examples taken from a real-world application domain.  ...  The e-Sol solution includes a standalone and distributed Warehouse Management System (WMS/e-WMS), and a Logistics Management System (LMS/e-LMS) on an integrated e-Business framework called e-Hub [11]  ...

Visual Specification of Multidimensional Queries Based on a Semantic Data Model [chapter]

Michael Böhnlein, Achim Ulbrich-vom Ende, Markus Plaha
2002 Vom Data Warehouse zum Corporate Knowledge Center  
Knowledge about the schema is essential for the quality of the query specification and responsible for the inferred decisions.  ...  Therefore, users need a multidimensional querying tool with a visual representation of the multidimensional schema to easily specify their information demands considering integrity constraints.  ...  The constraints for the query specification are discussed and a real-world example from a university application domain is presented.  ...
