Blueprints 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...
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...

Data Warehouses are collections of data coming from different sources, used mostly to support decision making and data analysis in an organization. To populate a data warehouse with up-to-date records that are extracted from the...
متن کاملLogical Optimization of ETL Workflows
Extraction-Transformation-Loading (ETL) tools are pieces of software responsible for the extraction of data from several sources, their cleansing, customization and insertion into a data warehouse. Usually, these processes must be completed in a certain time window; thus, it is necessary to optimize their execution time. In this paper, we delve into the logical optimization of ETL processes, mo...
متن کاملManaging ETL Processes
ETL tools allow the definition of sometimes complex processes to extract, transform, and load heterogeneous data into a data warehouse or to perform other data migration tasks. In larger organizations many ETL processes of different data integration projects are accumulated. Such processes can encompass common sub-processes, shared data sources and targets, and same or similar operations. Howev...
