Description: The source system refers to the set of data origins from which information is extracted and collected to be stored in a data warehouse. This system is fundamental in the architecture of information systems, as it ensures that the data is accurate, relevant, and up-to-date. Source systems can include operational databases, flat files, enterprise applications, and other systems that generate or store data. The quality of the data in the data warehouse largely depends on the quality of the data coming from these source systems. Therefore, it is crucial to establish extraction, transformation, and loading (ETL) processes that ensure data integrity and consistency. Additionally, source systems can vary in their structure and format, requiring specific tools and techniques for their integration into the data warehouse. In summary, the source system is the starting point in the data value chain, playing an essential role in informed decision-making and the generation of analytical reports.
