Today we let BW go and celebrate its 16 years on this planet as the initial third era bundled data warehouse. It changed how we assembled detailing frameworks; it made the possibility of standard substance; and it was a standout amongst the successful platform propelled by any product organization. As far back as BW on HANA had been introduces, these will encounter that brought about particular advantages, highlights and general upgrades.

SAP BW on HANA

SAP BW on HANA is the next wave of SAP's in-memory innovation vision that empowers SAP NetWeaver BW to utilize SAP HANA as a completely working in-memory database. Running SAP BW on HANA brings about significantly improved performance, improved organization and streamlined IT scene bringing about lower add up to cost of possession.

SAP Optimizes BW for HANA

SAP BW on HANA isn't a kludge, however it is an uneasy marriage of old and new innovation ideal models. BW was composed and improved for a more seasoned register and capacity display, one in which information volumes, memory assets, and capacity limits were still nearly little.

All the more particularly, BW was intended to keep running against customary RDBMS stages - including DB2, Oracle, SQL Server, and Sybase Adaptive Server Enterprise- - that composed information to and read information from physical plate. In-memory database outlines weren't obscure in this worldview; they were, in any case, very specific. For most potential adopters, an in-memory database was restrictively costly. HANA is an in-memory database stage. It doesn't simply run completely in physical memory (RAM) however is intended to abuse the greater part of the memory in a framework - including the distinctive sorts of on-chip reserves utilized by Intel and AMD CPUs. These comprise of the Level-1 (L1), Level-2 (L2), and Level-3 (L3) stores that are incorporated into the CPU bundle itself.

On-chip reserves go in estimate from 32 KB (for L1, per center) to 8 MB or more (for L3, shared among all centers). HANA tries to augment its utilization of on-chip reserving in light of the fact that the CPU can both compose information to and read information from on-chip store substantially more rapidly than to physical RAM. For instance, HANA will basically “pin” chunks of data or inquiries in the CPU's on-chip cache. Rather than fetching and re-fetch information or inquiries from slower physical memory, the CPU can recover it from the considerably quicker L1, L2, or L3 cache. With BW/4HANA, in any case, SAP says it's conveying considerably more than an in-memory optimized data warehouse stage for S/4HANA. The new BW/4HANA accompanies its own arrangement of HANA-native objects, enhanced help for the creation and requirement of refined information "temperature" strategies, and a bound together administration encounter. The new BW 4/HANA runs just on the HANA DBMS, dissimilar to its ancestor, which was affirmed to keep running against a few RDBMSs.

Migration to SAP BW on HANA:

The migration to SAP BW on HANA is very straightforward and requires no extra demonstrating or adaptation of existing data resources. BW is the main SAP application to be re-architected and revamped to take full advantages of the upgraded abilities of HANA. Handling that would customarily be done at the application (ABAP) layer is pushed down into the database where it can be ideally executed with the different computation and aggregation engines. BW incorporates two model writes upgraded for best performance on the HANA platform. Existing BW models can be utilized, much of the time, with just a parameter setting change.

Existing BW customer tools, similar to SAP Business Explorer, are supported by BW on SAP HANA. The HANA database likewise support coordinate customers like Microsoft Excel and SAP's Business Objects BI (Business Intelligence) devices.
