Data Warehouse In The Cloud – This blog post is about SAP Data Warehouse Cloud, which is the SAP Data Warehouse Cloud, SAP BW bridge. SAP offers its customers through RISE and SAP, the opportunity to move with a business transformation service (BTaaS) to the cloud. For BW customers, this means SAP BW to SAP Data Warehouse Cloud. SAP positions SAP Data Warehouse Cloud as a unique solution for Data Warehousing in the public cloud, with SAP BW/4HANA Private Cloud Edition (PCE) as the starting point for the transition. In this context, SAP BW bridge gives customers the opportunity to implement their new data warehousing use cases directly in the cloud while protecting, and maintaining their existing on-premises investments. The blog provides an overview of the SAP BW bridge, describes the transition from an existing SAP BW system to the cloud, and provides insight into a complete end-to-end greenfield scenario including a system demo in the SAP Data Warehouse Cloud.
SAP Data Warehouse Cloud is SAP’s offering for all data warehousing use cases. This SaaS (Software-as-a-Service) is based on SAP HANA Cloud. It integrates data, and analytics in a cloud solution that provides data integration, database, data warehouse, and analytics services. This enables customers to realize the full potential of a data-driven business. As a way to improve integration with SAP ERP systems, the SAP BW bridge enables ABAP-based data extraction and staging capabilities within the SAP Data Warehouse Cloud (see figure 1).
Data Warehouse In The Cloud
In the future, application-based migration of the existing SAP BW and SAP BW/4HANA event systems will be enabled. Then the SAP BW bridge will enable the seamless transfer of existing ETL processes into the dedicated SAP BW bridge Space in the SAP Data Warehouse Cloud. Here, many functions of ODP extractors, and ABAP code within the SAP Business Technology Platform (SAP BTP) ABAP environment can be hosted in the SAP Data Warehouse Cloud using the Cross-Space-Sharing method.
How To Migrate An On Premises Data Warehouse To Bigquery On Google Cloud
Within the SAP BW bridge, customers are able to perform data extraction and condition processing up to the CompositeProvider level. In other words, it is not possible to create new queries within the SAP BW bridge environment. In this regard, within the SAP BW bridge, there is no support for the OLAP engine, and the functionality depends on OLAP (for example, authorization to analyze, to query as a provider of information, to perform queries). Front-End tools do not have access to SAP BW bridge artefacts directly.
The SAP BW bridge environment is mainly intended for ODP-based source systems, which means that connection status is only available through Operational Data Provisioning (ODP). Non-SAP documents will be connected directly to the SAP Data Warehouse Cloud (see figure 2). Objects from the source SAP BW system(s) will be converted to the SAP BW bridge environment using the Conversion Tools, including the SAP BW queries.
To take full advantage of SAP’s data warehousing offerings, customers today must deploy both SAP BW/4HANA, and SAP Data Warehouse Cloud. In the future, the SAP BW bridge will enable customers to integrate these offerings into a single data warehouse solution in the cloud. With the SAP BW bridge, SAP caters to BW customers looking for a way forward from SAP BW NetWeaver, and SAP BW/4HANA (See figure 3).
SAP BW Customers will have the option in 2022 to convert their existing on-premises investments to the cloud through remote, and shell conversion. First, the SAP BW bridge conversion will be provided for SAP BW 7.4, and SAP BW 7.5 systems (initially as shell conversion, followed by remote conversion), then the conversion for SAP BW 7.3 systems (shell and remote conversion) will be available. In addition, the change will be available for SAP BW/4HANA 2021 (shell and remote conversion). For coverage releases, please refer to the road maps. Customers with a lower SAP BW release will need to upgrade their system(s) first, and then change the scale required for the SAP BW bridge in the SAP Data Warehouse Cloud. Please note that SAP BW systems 7.40, and below are already out of date (see figure 4). A dedicated blog post is available, see Transition to SAP Data Warehouse Cloud: Transition Path and Cloud Transition Steps.
Cloudera Data Warehouse Public Cloud Compaction Architecture
The SAP BW bridge artefacts outside the Business Technology Platform (SAP BTP) ABAP environment are accessible via remote tables using SAP HANA Cloud Smart-Data-Access (SDA) in a dedicated SAP BW bridge Space in the SAP Data Warehouse Cloud. The remote tables in the SAP BW bridge Space can then be used in regular SAP Data Warehouse Cloud Spaces through the SAP Data Warehouse Cloud cross-space sharing approach.
Add-ons are not supported in SAP BW bridge. Therefore, scheduling is not available within the SAP BW bridge. In this regard, SAP puts SAP Analytics Cloud Planning as a planning system, and in the future (early end of 2022) SAP Data Warehouse Cloud as a data planning foundation. Application development is not supported in SAP BW bridge. Any app development must be done through the Business Technology Platform App Building on SAP HANA, which customers must license, and use the standalone SAP Business Technology Platform ABAP Environment.
Customers who build a new data warehouse in the cloud with SAP Legacy systems as data sources will automatically migrate to a cloud-based system in the future. To manage the same level of data integration, and easy tasks as known from SAP BW/4HANA.
Customers with SAP BW (SAP BW 7.3 and above, any DB) moving their data warehouse to the cloud in order to protect their data, and their legacy data flows, but managing their data usage data with SAP Analytics Cloud or 3rd party customers on top. , and by expanding their data footprint to the cloud, and non-SAP sources.
Sap Data Warehouse Cloud: Sap Bw Bridge
Customers with on-premise SAP BW/4HANA looking for a cloud-based solution for their data storage operations. Starting with a mixed use case to integrate SAP BW/4HANA data, and SAP Data Warehouse Cloud data, and then easily move more and more SAP BW/4HANA data flows to the cloud, and successively switch to the latest SAP Data Warehouse Cloud. data entry method.
For example, the Greenfield method is shown in the following application (See Figure 5). This means if the customer is running SAP Data Warehouse Cloud together with a SAP BW bridge to connect SAP on-premises systems. This provides a proven SAP BW-based data integration technology for ABAP-based SAP systems, and enables a rich set of models in the SAP Data Warehouse Cloud.
The SAP BW bridge data, and processes are managed, and managed through the SAP UI5 environment called SAP BW bridge Cockpit. Implementation of new features is done within Eclipse through SAP BW Modeling Tools, and ABAP Development Tools. Within the SAP Data Warehouse Cloud, SAP BW bridge artefacts are accessible via remote tables, and can be used via the SAP Data Warehouse Cloud cross-space sharing approach. An SAP GUI is not required to access the SAP BW bridge environment.
In the following data flow (see figure 6) it can be seen, that the Eclipse environment with SAP BW Modeling Tools, and ABAP Development Tools are used. The well-known SAP data model is the basis of this application.
Data Warehouse Architecture: Traditional Vs. Cloud
In this case, the tables of “Airline” for commercial data, and “Airline carrier” for main data are checked. The left branch of the data model holds the sales data, the data is loaded from the SAP ECC system according to the old ABAP extractor. The right branch of the database contains the master data, the data that is loaded from the view CDS. As it can be seen, there is still a division into master data records, and master data attributes. Within the data flow, transformations, and data transfer methods are used to load data into the master DataStore Object, and the master data-loading InfoObject. Within the Composite Provider, the data will be combined with a join.
The SAP BW bridge component is mainly intended for ODP-based source systems. In this regard, customers have the option of creating source systems in the context of ODP. This means that ODP-BW, ODP-SAP, ODP-CDS, and ODP-SLT based source systems can be integrated. This provides some of the benefits of the Operational Data Provisioning Framework, such as Extract Once Deploy Many, data compression, and more.
A dedicated process chain is created for all branches in order to load data into InfoProviders. Chain processes are compared in the SAP UI5 area of the SAP BW bridge called the SAP BW bridge Cockpit (see figure 7).
If the customer wants to use the SAP BW bridge, the provisioning process is triggered by SAP. With that, there will be a dedicated Space for the SAP BW bridge in the SAP Data Warehouse Cloud Tenant itself, created by the provisioning system. This area then has the specific type “SAP BW bridge” (see figure 8).
Data Warehouse Platform Available In The Cloud |
In the created area of the SAP BW bridge Space, the connection (see figure 9a) to the SAP BW bridge environment, within the SAP Business Technology Platform, will be created which contains the SAP HANA Cloud Smart Data Access endpoint, and the HTTP ABAP endpoint. It is possible to connect only one SAP BW bridge System to the SAP Data Warehouse Cloud Tenant.
