Sap bw Study Notes (1)

Sap bw stands for business information warehouse, which is also known as SAP Business Intelligence after version 3.5.
The information integration layer in the overall architecture of SAP NetWeaver is tied to master data management and knowledge management. This layer is called information integration, it is the analysis part from the bottom layer of the enterprise to the top layer. However, this layer is not completely being analyzed, because it also contains data warehousing, Bi platform, and Bi suite) three levels.
Perhaps the precise explanation of BW is a key step in how to make business activities more efficient and convenient.
SAP Business Intelligence is an enterprise-class, complete, open and integrated solution that delivers actionable insight. However, this definition is basically accurate. This section describes BW's functions and application objects.
The bottom layer of BW, data warehousing. In the legendary data warehouse, the main tasks completed in this layer include ETL process (extraction, transformation, loading), data warehouse management and business modeling. In the ETL process, various types of metadata are processed and cleansed through various channels and methods, and thus converted into the data types in the unified format required by the system, so as to facilitate all subsequent needs. It is a crucial step in BW. After data warehouse management, the data is divided into different types, such as primary data, PSA, and ODS objects, for management. Business modeling is more difficult to grasp in a data warehouse. This content is basically closely related to the customer's needs and is suitable and efficient according to the needs. This skill is not covered by one or two days of theoretical study. It requires the accumulation of project experience.
The second layer is called Bi platform, which focuses on logic processing. It calculates, plans, and further processes data warehousing according to requirements, this layer is more of a unified processing and basic encapsulation of data. In this layer, the completed content includes business calculations, planning and forecasts, exception scanning, alerting, query pre-calculation, caching, background printing, and data mining. Main products include OLAP, metadata management, data mining, analysis process designer and BPS (business planning and simulation ).
The third part is Bi Suite, which is actually re-processing the items in Bi platform, the main content is to add some elements of business intelligence to the Bi platform content, such as diversified query selection, automatic report generation, multi-dimensional data analysis, and information publishing, public third-party analysis interfaces and specific web page representations. With this piece, the BW of SAP is more Article , More professional.
BW's current market is very large and the supply-demand relationship is unbalanced. It should be quite popular in recent years. SAP depends on its product completeness and powerful integration functions. On the one hand, it has more room for project selection and accepts some large projects. On the other hand, it promotes the platform, it also brings unlimited business opportunities. After understanding some of the meaning of SAP system software, you can start using it in this industry. IBM and Accenture both have a large business. However, they are more part owners of SAP. At present, SAP's biggest competitor is Oracle, But Oracle is also a support object for SAP systems, so SAP and Oracle are partners. It's complicated.
By the way, I would like to add that the SAP system is so easy to use that it predefines many useful templates. When the implementation becomes easy and beautiful, enterprises naturally think that you are better.
Now, let's talk about these things in the future.
