Benchmarking ETL Workflows [chapter]

Alkis Simitsis, Panos Vassiliadis, Umeshwar Dayal, Anastasios Karagiannis, Vasiliki Tziovara
2009 Lecture Notes in Computer Science  
In this paper, we identify common characteristics of ETL workflows in an effort of proposing a unified evaluation method for ETL.  ...  Each ETL tool uses its own technique for the design and implementation of an ETL workflow, making the task of assessing ETL tools extremely difficult.  ...  First, we provide a principled way for constructing ETL workflows (Section 2).  ...

HTAP With Reactive Streaming ETL

Carl Camilleri, Joseph G. Vella, Vitezslav Nezval
2021 Journal of Cases on Information Technology  
Finally, a reactive streaming ETL pipeline is implemented which connects these two DBMSs. Separate benchmarks show that OLTP events can be streamed to an OLAP database within a few seconds.  ...  Then, benchmarks on two industry standard DBMSs empirically show that, under an OLTP workload, a row-store DBMS sustains a 1000 times higher throughput than a columnar DBMS, whilst OLAP queries are more  ...  , can support actionable and reactive decisions when connected via an efficient ETL pipeline built on the principles of the Reactive Manifesto.  ...

DIPBench: An independent benchmark for Data-Intensive Integration Processes

Matthias Bohm, Dirk Habich, Wolfgang Lehner, Uwe Wloka
2008 2008 IEEE 24th International Conference on Data Engineering Workshop  
Due to the absence of an independent and universal benchmark for data-intensive integration processes, we propose a scalable benchmark, called DIPBench (Data Intensive Integration Process Benchmark), for  ...  and Extraction Transformation Loading (ETL) tools.  ...  Further, also an ETL Benchmark with quality metrics was already discussed in [18] .  ...

DIPBench Toolsuite: A Framework for Benchmarking Integration Systems

Matthias Bohm, Dirk Habich, Wolfgang Lehner, Uwe Wloka
2008 2008 IEEE 24th International Conference on Data Engineering  
A first step towards sufficient techniques was the specification of a universal benchmark for integration systems.  ...  However, we see the requirement for providing a sophisticated toolsuite in order to minimize the effort for benchmark execution. This demo illustrates the use of the DIPBench toolsuite.  ...  ACKNOWLEDGMENT We want to thank the students Katrin Braunschweig, Romain Treboux and Dirk Alsfaßer for their efforts on extending and enhancing the Initializer tool.  ...

Towards Equivalent Transformation of User Preferences in Cross Domain Recommendation [article]

Xu Chen and Ya Zhang and Ivor Tsang and Yuangang Pan and Jingchao Su
2022 arXiv   pre-print
Extensive experiments on three public benchmarks demonstrate the effectiveness of ETL compared with recent state-of-the-art methods. Codes and data are available online:  ...  Based on this assumption, we propose an equivalent transformation learner (ETL) which models the joint distribution of user behaviors across domains.  ...  In ETL, we do not tune hyper-parameter 𝜂 and fix it as 1.0 on the three benchmarks for simplicity.  ...

GEM: Requirement-Driven Generation of ETL and Multidimensional Conceptual Designs [chapter]

Oscar Romero, Alkis Simitsis, Alberto Abelló
2011 Lecture Notes in Computer Science  
It is of great importance for the business of an enterprise to facilitate and automate such a process.  ...  The goal of our research is to provide designers with a semi-automatic means for producing conceptual multidimensional designs and also, conceptual representation of the extract-transform-load (ETL) processes  ...  For guaranteeing the MD design principles (see Section 2.2), factual and dimensional nodes must be related properly.  ...

Risk Management and Portfolio Optimization for Volatile Markets [chapter]

Svetlozar T. Rachev, Borjana Racheva-Iotova, Stoyan V. Stoyanov, Frank J. Fabozzi
2010 Handbook of Portfolio Construction  
Along with being a superior risk measure, SETL enables an elegant approach to risk budgeting and portfolio optimization Finally, we mention alternative investment performance measurement tools.  ...  We describe a framework of a system for risk estimation and portfolio optimization based on stable distributions and the average value-at-risk risk measure.  ...  If the benchmark is zero, r b = 0, and instead of ETL we use the standard deviation, which is an uncertainty measure, then the optimization problem transforms into the classical Markowitz problem.  ...
