A Pull-Based Approach for Incremental View Maintenance in Mobile DWs

چکیده
With the rapid growth in mobile and wireless technologies and the availability, pervasiveness and cost effectiveness of wireless networks, mobile computers are quickly becoming the normal front-end devices for accessing enterprise data. In this paper, we are addressing the issue of efficient delivery of business decision support data in the form of summary tables to mobile clients − mobile OLAP views. More precisely, we address the OLAP view update problem for maintaining the consistency between a mobile OLAP view and the underlying DW server: the content of the mobile OLAP view could become incoherent with the DW server when the content of the DW server is changed. We propose a pull-based approach that enables an OLAP view to be updated at a mobile client in an incremental manner, requiring the client to request changes to its view to the server. We demonstrate the feasibility of our approach with experimental results.

Scalable Maintenance of Multiple Interrelated Data Warehousing Systems
The maintenance of data warehouses(DWs) is becoming an increasingly important topic due to the growing use, derivation and integration of digital information. Most previous work has dealt with one centralized data warehouse only. In this paper, we now focus on environments with multiple DWs that are possibly derived from other DWs. In such a large-scale environment, data updates from base sourc...

Data warehouse is a repository of integrated data that is collected from various sources. Data warehouse has a capability of maintaining data from various sources in its view form. So, the view should be maintained and updated during changes of sources. Since the increase in updates may cause costly overhead, it is necessary to update views with high accuracy. Optimal Delta Evaluation method is...

Data warehouses (DW) are built by gathering information from several information sources (ISs) and integrating and materializing it into one repository customized to user's needs. Some of the most recently proposed algorithms for the incremental maintenance of such materialized DWs, such as SWEEP and PSWEEP, ooer several signiicant advantages over previous solutions, such as high-performance, n...
متن کاملUsing Schema Transformation Pathways for Incremental View Maintenance
In heterogeneous data warehousing environments, autonomous data sources are integrated into a materialized integrated database. The schemas of the data sources and the integrated database may be expressed in different modelling languages. It is possible for either the data or the schemas of the data sources to be updated. Incremental view maintenance is one of the problems being addressed in da...
