The Evolution of the SAP CDS View

A View may be defined to be a projection of several entities and it is possible to create an SAP CDS View as a design-time file in the storage repository of the SAP HANA Extended Application Services (SAP HANA XS).

The SAP CDS View was first launched by SAP as a programming model in-built into SAP HANA. It enables direct and seamless access to the underlying tables of the HANA database. The objective here is to facilitate logic from the application server to the client-side database named ‘Code-to-Data’ or ‘Code Pushdown’ by SAP. Later, this logic can be extracted by the SAP CDS View from the ABAP applications and executed on the database.

In the past, typically the application server and not the database server has been used for data modeling. After SAP introduced a new infrastructure for data modeling done at the database level using Core Data Services (CDS), popularly termed SAP CDS View, there were several benefits that can be leveraged now.

Here are some of the benefits of the SAP CDS View.

  • It is a code-to-data technology in ABAP. Here, SAP CDS View carries out all computing and calculations on the database layer instead of the application server.
  •  Being less conventional in SE11 views, the features of SAP CDS View may be accessed outside the SAP native applications
  • Since SAP functions independently of the database, CDS View on SAP can be operated on any database platform that is supported by it.
  • Automatic client handling as well as Aggregation and Numeric functionalities are supported by the SAP CDS View.

These are some of the benefits of the SAP CDS View.

Streamlining Data Migration: Oracle to Snowflake Transition Explored

Image
In today's data-driven era, seamless data migration between platforms has become a pivotal strategy for organizations looking to optimize their data management and analytics capabilities. One such transition gaining significant attention is the move from Oracle to Snowflake. In this piece, we dive into the intricacies of migrating data from Oracle to Snowflake, outlining the advantages and considerations along the way.   Understanding the Oracle to Snowflake Transition: Transitioning from Oracle to Snowflake involves moving data from Oracle databases, known for their reliability and robustness, to Snowflake's cloud-based data warehousing platform. Snowflake's architecture offers features such as elasticity, scalability, and native support for structured and semi-structured data, making it an appealing destination for data migration.   Key Advantages of Migrating from Oracle to Snowflake:   Scalability and Elasticity: Snowflake's architecture is designed

SAP Data Extraction with The SAP Extractor

Image
  The SAP Extractor (known as the BW Extractor in the past) is typically used for SAP data extraction. The tool extracts data from the source systems and stores it in downstream data warehouses or business intelligence systems. The SAP Extractor, a data management feature of SAP was launched mainly for SAP data extraction for input into the SAP BW application. Even when an SAP user is not on the SAP Business Warehouse, the Extractor can still be used for data extraction. For information about SAP data extraction, click here.     SAP data is used to query Data Services leading to quicker batch processing (previously known as data transformation) based on a pre-defined workflow. Since the Extractor is a program in SAP ERP, it can be triggered for SAP data extraction to transfer to BW. The options here are either a standard DataSource or a customized DataSource with comprehensive details of full-load delta processes. SAP BW remotely controls the data transfer part of the program.

The Structure of the SAP Data Lake

Image
In April 2020, SAP launched the SAP HANA Data Lake with the goal of strengthening its existing data storage capabilities and offering customers an affordable storage system. Included were an SAP HANA native storage extension and SAP Data Lake. From the very introduction of this system, several cutting-edge capabilities were added to this package. This led to the SAP Data Lake of the SAP IQ cloud-based system being considered at par with other competitors such as Microsoft Azure and Amazon Simple Storage Service. The structure of the SAP Data Lake is unique and is unlike other data lakes. It resembles a pyramid that is segmented into three parts. The top section holds data that is critical for businesses and is accessed regularly and processed for daily operational requirements. This is vital data often referred to as hot data and the cost of storing it in the SAP Data Lake is the highest. The middle of the pyramid is for storing data that is infrequently used but not as unimportant a
