6.2 Data Sourcing and Data Egress

Data Sourcing and Data Egress refer to the processes of acquiring data from both internal and external systems (data sourcing) and transferring it to other environments or applications (data egress). Data sourcing involves identifying, extracting, and collecting data from various sources, such as transactional systems, third-party providers, or data warehouses. This data is then processed and integrated to support business operations, reporting, or analytics. In contrast, data egress deals with the movement of processed data from its original system or database to other platforms, systems, or end-users. This may include sharing data with downstream applications, regulatory reporting systems, or external partners. Both data sourcing and egress must be carefully managed to ensure data quality, security, and compliance with regulatory standards, particularly when handling sensitive financial or customer information. Effective strategies for data sourcing and egress are vital to ensuring that the right data is delivered to the right destinations in a timely, secure, and accurate manner. In DFCS, data sourcing is facilitated through Ingress Connectors using External Data Descriptors for each entity.
