Meshing Streaming Updates with Persistent Data in an Active Data Warehouse

N. Polyzotis, S. Skiadopoulos, P. Vassiliadis, A. Simitsis, N. Frantzell
2008 IEEE Transactions on Knowledge and Data Engineering  
In a nutshell, an active warehouse is refreshed on-line and thus achieves a higher consistency between the stored information and the latest data updates.  ...  In this article, we focus on a frequently encountered operation in this context, namely, the join of a fast stream S of source updates with a disk-based relation R, under the constraint of limited memory  ...  Since our focus is active warehousing, we assume that the warehouse receives S from the operational data sources in an on-line fashion.  ...

Automating the loading of business process data warehouses

Malu Castellanos, Alkis Simitsis, Kevin Wilkinson, Umeshwar Dayal
2009 Proceedings of the 12th International Conference on Extending Database Technology Advances in Database Technology - EDBT '09  
In this paper, we show how to automate the population of the generic process warehouse by tracking business events from an application environment.  ...  We build upon our previous work that described the design and implementation of a generic process data warehouse for use with any business processes.  ...  Consequently, the active (or idle) time of an activity in a business process has a different meaning than the active time of an ETL operator.  ...

HYBRIDJOIN for Near-Real-Time Data Warehousing

M. Asif Naeem, Gillian Dobbie, Gerald Weber
2011 International Journal of Data Warehousing and Mining  
An important component of near-real-time data warehouses is the near-real-time integration layer.  ...  One important element in near-real-time data integration is the join of a continuous input data stream with a disk-based relation.  ...  Frequently used terms are zero-latency, active, realtime or near-real-time data warehouses.  ...

2000 IEEE Communications Magazine  
This paper describes a prototype infrastructure for the measurement, storage and correlation of network data of different types and origins from AT&T's commercial IP network.  ...  We focus first on some novel aspects of the measurement infrastructure, then describe analyses that illustrate the power of joining different measured data sets for network planning and design.  ...  An otherwise idle router peers with a gateway router, and collects routing updates which are then exported to the warehouse.  ...

Tactile SLAM: Real-time inference of shape and pose from planar pushing [article]

Sudharshan Suresh, Maria Bauza, Kuan-Ting Yu, Joshua G. Mangelson, Alberto Rodriguez, Michael Kaess
2021 arXiv   pre-print
This is applied towards tactile exploration of an unknown object by planar pushing. We consider this as an online SLAM problem with a nonparametric shape representation.  ...  In this work, we present a method to estimate both object shape and pose in real-time from a stream of tactile measurements.  ...  In our online setting, we directly update the Cholesky factor LL T = K + σ 2 noise I with new information.  ...
