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 کاملInstant-On Scientific Data Warehouses - Lazy ETL for Data-Intensive Research
In the dawn of the data intensive research era, scientific discovery deploys data analysis techniques similar to those that drive business intelligence. Similar to classical Extract, Transform and Load (ETL) processes, data is loaded entirely from external data sources (repositories) into a scientific data warehouse before it can be analyzed. This process is both, time and resource intensive an...
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 کاملData Verification in Etl Processes
The ETL processes are responsible for the extraction of the data from the external sources, transforming the data in order to satisfy the integration needs and for loading the data into the data warehouse. On the other hand, in the data mining world, there is a special concern on using the metrics for efficient classification algorithms. One of these approaches is the one that uses metrics on p...
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...
