ETLtilnærming

ETLtilnærming refers to the process of Extract, Transform, Load, which is a fundamental data integration methodology. This approach is used to consolidate data from various sources into a single, unified data store, typically a data warehouse. The "Extract" phase involves reading and identifying data from disparate source systems, which can include databases, flat files, APIs, and other applications. The "Transform" phase is where the extracted data is cleansed, validated, and converted into a standardized format. This can involve operations like data type conversion, deduplication, aggregation, and the application of business rules. Finally, the "Load" phase involves writing the transformed data into the target data store, such as a data warehouse or data lake, where it can be analyzed and used for reporting and decision-making. ETLtilnærming is crucial for ensuring data quality, consistency, and accessibility across an organization. It enables businesses to gain deeper insights from their data by providing a consolidated and reliable view. This process is often automated using specialized ETL tools and software.
