Logical 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 کاملModeling and managing ETL processes
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. The design, development and deployment of ETL processes, which is currently, performed in an ad-hoc, in house fashion, needs modeling, design and methodological foundations. Unfortunately, the resear...
متن کاملQuery Optimizer for the ETL Process in Data Warehouses
ETL (Extraction-Transformation-Loading) process is responsible for extracting data from several sources, cleansing, transforming, integrating and loading into a data warehouse. Extraction process accesses large amount of data by executing several complex queries in source databases. These queries are repetitive and executed at regular interval to refresh the data warehouse. Extraction of data f...
متن کاملA Semantic Approach towards CWM-based ETL Processes
Nowadays, on the basis of a common standard for metadata representation and interchange mechanism in data warehouse environments, Common Warehouse Metamodel (CWM) – based ETL processes still has to face significant challenges in semantically and systematically integrating heterogeneous sources to data warehouse. In this context, we focus on proposing an ontology-based ETL framework for covering...
متن کاملXML based Framework for ETL Processes For Relational Databases
In Data Warehousing, Extraction-Transformation-Loading (ETL) are the key tasks that are responsible for the extraction of data from several sources, their cleansing, customization and insertion into data warehouse [10]. More specifically ETL tools are category of specialized tools with the task of dealing with data warehouse cleaning and loading problems. These task are very critical in every d...
