SAP BW (Business Warehouse) is one of the primary modules
regarding SAP. Some of the additional modules are SAP HCM (Human Capital Management), SAP FICO(Financial Accounting and Controlling), SAP QM
(Quality Management), SAP PP (Production Planning), SAP PS (Project System),
and SAP MM (Material Management). To know what is SAP BW, you should initially
understand the Data Warehousing functionality. You should then explain various
options for SAP Data Warehousing. Then, you should be ready to compare SAP BW
with another best-of-breed tool. Ultimately, you should also read about SAP
BW’s Data Mining functionality and numerous services offered by SAP BW.
Hence, the tutorial is segmented toward the resulting five
sections:
What is SAP BW and Data Warehouse?
Data Warehouse is a combination of data designed to promote
management decision-making. A wide variety of data presenting a clear idea of
business requirements at a single point in time is included in a Data
Warehouse. It is a cause of a company’s electronically stored data. To
facilitate reporting and analysis, data warehouses are created. Data
Warehousing is a generally used term for integrating data from multiple
databases beyond an enterprise.
The averages to retrieve and analyze data, to obtain,
transform and load data, and to maintain the data dictionary are also deemed
essential elements of a data warehousing system.
Generating a Data Warehouse essentially involves developing
systems to extract data from transactional systems. It also includes
establishing a warehouse database system that advises executives on flexible
access to the data.
Some of the benefits of doing a Data Warehouse are provided
below:
- Rapid turnaround time for reporting and analysis
- Carrying out new kinds of analyses
- Data integration from numerous sources
- Data standardization, a “single version of the truth”
- Cost reduction to access historical data
- Supporting ad hoc reporting and inquiry
Also, Data Warehouse implementation instructions involve
changing data from multiple source systems into a particular format. We
pleasure have more confidence in the correctness of our data. And accurate data
is the foundation for strong business decisions. A Data Warehouse originally
stores tons of historical data, so users can penetrate through the data across
various periods and do projections for the prospect accordingly. This variety
of data usually is not simple to store in a transactional database or produce
reports from a transactional system.
Companies that become created data warehouses and delivered
corresponding BI systems implementation have created lots of revenue and have
collected more money than companies that haven’t done so. Companies will have
several advantages by managing data warehouses. For instance, big giants like
Apple, eBay, and Walmart have any of the biggest data warehouses. Avis Europe,
after performing data warehouse, has witnessed the customer-centric view of
information.
SAP BW (Business Warehouse) is a data warehouse extract from
SAP that is tightly combined with SAP ERP software.
Various Options for SAP Data Warehousing
SAP BW provides business executives to examine the data and
plan the business processes accordingly. It allows an integrated view of the
data. However, SAP BW is not the exclusive option available for Data
Warehousing in SAP. There are essentially two paths for Data Warehousing in
SAP:
Managing a Data Warehousing Modelling and Management
application: SAP BW is SAP’s Data Warehousing modelling and Management
application.
Using different tools: You can build and manage a Data
Warehouse utilizing unique tools such as HANA, Sybase IQ databases, SAP Data
Services to convert and load the data, and SAP Business Objects (BOBJ) for
reporting. Then, you could reasonably use additional tools such as SAP Data
Quality Management tool, SAP Information Steward, etc.
These claims may sound daunting, but you should know the
fact that Data Warehousing is itself an elaborate discipline. In short, SAP
allows tools ranging from the platform-agnostic (such as SAP Data Services) to
the platform combined tool (SAP BW).
Comparison of SAP BW with Alternatives
Now that we get what is SAP BW, let’s consider alternatives
obtainable on the market. We have many other best-of-breed vendors such as
QlikView, Tableau who is leading SAP in some capabilities. Though, they don’t
offer some of the capabilities that SAP BW produces. BI suites such as Pentaho,
MicroStrategy are fighting fairly with SAP’s Business Object series.
The principal reason why SAP BW has the biggest aggressive
advantage is its integration with other SAP applications (like EPM – Enterprise
Performance Management). Still, SAP has some shortcomings in the areas of
usability and user knowledge when corresponded to its other competitors.
SAP BW’s Data Mining Functionality
SAP BW allows Data Mining functionality. Data Mining is a
method that is used to recognize patterns in a significant dataset. SAP BW’s
Data Mining functionality enables business executives to design the processes
effectively, as the data that’s being in the Data Warehouse helps them in
better preparation.
Benefits of SAP BW
SAP BW gives various benefits which present it as one of the
best tools. Some of those are noted below:
- SAP BW suggestions ‘Business Content’. It gives ready-made
objects such as Info Cubes, reports, Multi Providers, etc.
- The versatility that SAP BW offers is tremendous. It’s very
simple to customize the regular content.
- It offers excellent query performance with very little
administration effort.
- It offers the capability to analyze multidimensional data
experts.
- It easily combines with other platforms.
- It serves as a good link to the planning and performance
applications. With this method, you can gain penetrations from the data and
improve business processes.
SAP BW Overview
SAP BW attains for SAP Business Warehouse. It is essentially
used to integrate data from multiple sources, transform and combine data,
perform data cleansing, and collect the cleansed data.
Generally talking, data warehousing is described as the
process of data extraction, conversion, and loading of data to the warehouse
and the way of the data by end-users and applications. It is very beneficial in
providing business knowledge through analytics that is based on data stored
within it and helps companies in building management decisions from time to
time. Data warehousing keeps a single data source that is managed by multiple
applications across functions, and/or locations, depending on the standard
interface requirements, and places it in perspective depending on the business
requirement. The information generated by this mechanism is generally reliable
and helpful in studying past courses or making a forecast. Additionally, data
warehousing simplifies combination with various different forms based on
technology, while also improving the speed with which information is processed
and made available.
The main five difficulties in the world of Data Warehousing
are supposed to be:
- Quality of data entry
- Collecting and storing data
- Finding data when you need it
- Turning data into useful information
- Distinguishing what makes and doesn’t need to be secure, and
having it safe
SAP BW Architecture
Let’s take a glance at the architecture of SAP BW. SAP BW
primarily has a 3-tier architecture:
- Database Server
- Application Server
- Presentation Server
A close appearance at each of these tiers will assist you to
understand what SAP BW is all about.
Database Server: This is the position where data is stored
physically. It involves DSO (Data Store Objects), PSA (Persistent Staging Area),
Info cubes, etc.
Application Server: This signifies based on Online
Analytical Processing (OLAP) processor. OLAP essentially does multidimensional
data analysis. It is primarily done to get the data stored in the database
server.
Presentation Server: It controls the describing and data
access.
It starts with access mechanisms for recovering data from
mixed operational data resources. That data is replicated through a conversion
model and stored in the data warehouse (DW). The type of data elements in the
DW and in the data sources and the transformation rules which connect them, are
referred to as ‘metadata’. Metadata is the averages by which the end-users find
and understand the data in the warehouse. The data conversion and transfer
procedures are completed whenever a revise to the warehouse data is favored.
Various parts of the warehouse may require updates at different times, some at
normal periods, for example, weekly, monthly, and some on designated dates.
Following are the actions included in a standard SAP BW
flow:
- Extract data from expert systems (SAP or non-SAP).
- Stage the data in a Determined Staging Area (PSA). Practice
this to hold all the data obtained from various sources.
- Clean, load, and store the data in Data Store Object (DSO).
- Inspect the data by the different dimensions in Info cube.
- Make the data ready to Business Explorer by OLAP processor.
- Perform the data prepared to Open Hubs, SAP/non-SAP systems,
etc. as per the business requirement.
