An Overview Of SAP Change Data Capture

Change Data Capture (CDC) identifies and loads only changed data. You can use SAP Change Data Capture to get all the attributes of CDC to locate and extract only the incremental data added to the database after the last refresh.

The Replication Server, also known as the target database gets data from the source database in real time and captures the data. Data Services connects to Replication Server to capture changed data, subscriptions, and configurations. For metadata information, Data Services connects directly to source databases to capture data.

Users of Microsoft need a connector that extracts only the delta between two sets of data. Delta is the changed data in a dataset regardless of whether it is Update, Insert, or Delete. A delta extraction connector uses the SAP Change Data Capture feature that is in-built in SAP systems to identify the delta in a dataset. The SAP CDC capabilities in Data Factory use the SAP Operational Data Provisioning (ODP) framework to replicate the delta in an SAP source dataset.


The SAP Change Data Capture connector is the core of the SAP CDC capabilities. It can connect to all SAP systems that support ODP, which includes SAP ECC, SAP S/4HANA, SAP BW, and SAP BW/4HANA. The solution works either directly at the application layer or indirectly via an SAP Landscape Transformation Replication Server (SLT) as a proxy.

SAP CDC does not rely on watermarking to extract SAP data either fully or incrementally. The data the SAP CDC connector extracts includes not only physical tables but also logical objects that are created by using the tables. An example of a table-based object is an SAP Advanced Business Application Programming (ABAP) Core Data Services (CDS) view.

S3 Data Lake: Transforming Data Storage and Accessibility

Image
 An S3 data lake is a powerful solution for organizations seeking scalable, cost-effective, and flexible data storage options. Built on Amazon Web Services’ Simple Storage Service (S3), this approach allows businesses to store vast amounts of structured and unstructured data in a centralized repository. By leveraging S3's scalability and reliability, companies can manage their data seamlessly and support a wide range of analytics and processing tools.   The hallmark of an S3 data lake is its ability to store data in its raw form. Unlike traditional databases, which often require preprocessing and strict schemas, an S3 data lake accepts data in its original state. This capability enables businesses to ingest data quickly from multiple sources, including IoT devices, streaming platforms, and enterprise applications. With the data centrally stored, organizations can apply various analytical frameworks, such as machine learning algorithms or big data processing tools, to extrac...
