Lazy ETL in Action: ETL Technology Dates Scientific Data
Both scientific data and business data have analytical needs. Analysis takes place after a scientific data warehouse is eagerly filled with all data from external data sources (repositories). This is similar to the initial loading stage of Extract, Transform, and Load (ETL) processes that drive business intelligence. ETL can also help scientific data analysis. However, the initial loading is a ...
متن کاملDistributed ETL
This paper provides the motivation, implementation details, and evaluation of a lightweight distributed extract-transform-load (ETL) service designed for large scale ingestion of real-time data.
متن کاملMerging DEL and ETL
This paper surveys the interface between the two major logical trends that describe agents’ intelligent interaction over time: dynamic epistemic logic (DEL) and epistemic temporal logic (ETL). The initial attempt to “merge” DEL and ETL was made in [12] and followed up by [11] and [29]. The merged framework provides a systematic comparison between these two logical systems and studies new logics...
متن کاملBenchmarking ETL Workflows
Extraction–Transform–Load (ETL) processes comprise complex data workflows, which are responsible for the maintenance of a Data Warehouse. A plethora of ETL tools is currently available constituting a multi-million dollar market. 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. In this paper, we...
متن کاملBlueprints for ETL workflows
Extract-Transform-Load (ETL) workflows are data centric workflows responsible for transferring, cleaning, and loading data from their respective sources to the warehouse. Previous research has identified graphbased techniques that construct the blueprints for the structure of such workflows. In this paper, we extend existing results by explicitly incorporating the internal semantics of each act...
