What is Core Data Service View in SAP

Core Data Service (CDS) has been created by SAP and is a semantically rich data definition language. With CDS View SAP, you can define and consume models on the database without the use of the application server. CDS views is a specialized and optimized platform for designing data models that can be moved outside applications with the help of OData services.

This post will go into the details and the many intricacies of the CDS View SAP beginning with what is SAP CDS.



What is SAP CDS

SAP CDS is a short form of SAP Core Data Service. It is a framework for data modeling that ensures data models are defined and consumed not on the more common application server but on the database server and leverages the robust in-memory database of SAP HANA to meet the requirements of real-time performance. This can be done by users through maximized operations at the database level, leading to a reduction in application execution time and quick retrieval of databases. SAP CDS is used to create data models that can be shown to clients by application servers such as UI and CDS View SAP.

CDS View SAP

CDS View SAP was introduced as the new programming model of SAP. The Core Data Service Views virtual data models that are in-built in SAP HANA allow direct access to the underlying tables of the HANA database. The objective of the CDS View SAP is to facilitate logic to the client-side database from the application server called ‘Code-to-Data’ or ‘Code Pushdown’ by SAP. Logic is extracted from the ABAP applications by CDS View SAP and executed on the database.

Benefits of CDS View SAP

Some of the benefits of CDS View SAP are as follows.

CDS View SAP is a code-to-data technique in ABAP and all calculations and computations are carried out on the DB layer instead of the application server.

The features of CDS View SAP are less conventional in SE11 views and can be accessed outside the native SAP applications.

CDS View SAP can be run independently of the database on any database platform that is supported by SAP.

Client handling is automatically supported by CDS which can publish ODATA service annotations directly from CDS views.

Types of CDS View SAP

There are two types of CDS View SAP. The first is the HANA CDS Views while the other is the ABAP CDS views. After its launch, CDS View SAP could be had only in the SAP HANA ecosystem. But presently, CDS is also enabled in SAP NetWeaver as ABAP. This helps developers to use the tools of programming ABAP in the ABAP layer during the execution of the code in the database.

SAP CDS supports multiple capabilities. These include relationship definitions, conceptual modeling, and built-in functions and extensions, more than what the previous tools offered.

The Unique Architecture of the SAP HANA Data Lake

Image
In April 2020, SAP launched the HANA Data Lake that added more power to the existing cloud-based business ecosystem. Users benefitted from a cost-effective storage system from the package that consisted of a native storage extension and a relational SAP data lake. From the start, this data lake was considered to be as feature-rich as the existing players like Microsoft Azure and Amazon S3.  What makes SAP data lake stand out among its competitors is its unique architecture. Organizations have the option of storing data that is frequently used and regularly accessed in one layer while moving other not-so-critical data in low-cost storage layers of SAP HANA. Visualize the SAP data lake as a pyramid that has three layers. The top of the pyramid houses the most important data of an organization that is used in the regular course of business. Hence the cost of storing this data is the highest as it is frequently accessed for analytics or reporting. In the second layer of the ...

The Unique Architecture of the SAP Data Lake

Image
SAP launched HANA Data Lake in April 2020, intending to provide users with an advanced as well as a very cost-effective data storage repository. The complete package consists of a native storage extension and an  SAP Data Lake   that is standard across all models and versions. The architecture of the SAP Data Lake is unique and stands out from other forms of data lakes. Businesses have the option to store data that is frequently used and accessed (hot data) segregated from data that is not used much (warm data) in the Native Storage Extension (NSE) of SAP HANA. The SAP Data Lake may be visualized as a pyramid with three distinct layers. On the top part of the pyramid is space offered to businesses to store the data which is critical for daily operations and has to be accessed daily. Since this data has very high demand, the storing cost too is the highest among all the three segments. The middle layer of the pyramid is for organizations to store data that is no...

As a central repository that holds all the bid data from various different sources, a data lake is the vast, richest pool of raw data, the purpose of which is undefined. Data from this lake is then put to use for analytics and machine learning by organizations. A data lake is used for storing both relational and non-relational data from devices, apps, and users. Different types of analytics, such as machine learning, big data analytics, textual search, SQL queries, and real-time analytics can be derived from a data lake. It has both curated and non-curated data. An SAP data lake is easy to set up and can ingest data from on-premise or from a cloud warehouse. According to a survey, 90% of businesses believe that big data initiatives help them determine future success. A data lake allows data engineers, data scientists, and business analysts to access information using the tools and applications of their choice. There’s a lot of value in a data lake for businesses, the ability to harnes...
