Data extraction plays a major role in designing a successful DW system. Different source systems may have different characteristics of data, and the ETL process will manage these differences effectively while extracting the data. “Logical data map” is a base document for data extraction. This sho...
ETLis a process that extracts the data from different source systems, then transforms the data (like applying calculations, concatenations, etc.) and finally loads the data into the Data Warehouse system. Full form of ETL is Extract, Transform and Load. It’s tempting to think a creating a ...
This technology that aids in taking business decisions on the fly is known as real-time business intelligence. ETL being the core of the Data Warehousing process faces numerous challenges while being implemented in real-time. One of the challenges is to how to order the data being pushed into...
A computer software architecture to automatically optimize the throughput of the data extraction/transformation/loading (ETL) process in data warehousing applications. This architecture has a componentized aspect and a pipeline-based aspect. The componentized aspect refers to the fact that every ...
2. ETL Process Data Warehousing is the process to store data from multiple sources to a single data store that is loaded to Data Warehouse which can be a text file, images, spreadsheet, operation data, relational/non-relational data, sensitive data, sensor data, etc., but heterogeneous data...

Data Warehousing Project - ETL Design PhaseData Warehousing > Data Waraehouse Design > ETL Task DescriptionThe ETL (Extraction, Transformation, Loading) process typically takes the longest to develop, and this can easily take up to 50% of the data warehouse implementation cycle or longer. The ...
Short for Extract, Transform, and Load, ETL is a crucial data processing method used in data warehousing and analytics. Businesses often use the ETL process when they have data from multiple sources that they need to combine into a single, unified database. This consolidation allows for better...
Data quality in a typical Data Warehouse (DW) environment is critical. The process of transferring data from different sources into the DW environment, known as ETL (Extraction, Transformation, and Load), usually takes care of improving the data quality. However, it is not unusual to identify ...
Surrogate Key Pipeline (SKP) is one of the key functionalities in the refreshment process of the DW [17]. After preparing data in the T step of the ETL, a large part of this data is intended to be loaded in the fact tables. A “fact” table in the DW represents a focus of interes...
