There are so many approaches to SAP data management and business intelligence -- many of them offered by SAP itself -- that one can be forgiven for not grasping them all. With the roster evolving annually, some overarching framework of understanding usually has to be in place before an organization can buy third-party and SAP data management products and use them effectively in their BI applications.
The practical methods involve using either the data warehouse modeling and management application, SAP Business Warehouse (BW), or a mix of SAP and third-party tools. But data warehousing is really a discipline for integrating and managing data over time, according to one consultant and SAP mentor. It's also important to sift through SAP data management buzzwords and big data hype and instead elevate plain-English words like honesty, integrity and transparency as signposts for quality BI and analytics. Honesty, for example, means telling the truth about the accuracy of data so users know how reliable it is for prediction and other analysis.
But no SAP data management strategy is complete without a firm grasp of critical technologies, including Hadoop, today's most talked-about technology for big data -- and the foundation of many SAP data management and BI projects. It's also important to understand how well SAP products such as HANA and Data Services integrate with Hadoop's various parts.
Nowadays, analytics and visualization software are the mechanisms through which BI users interact with data. It's difficult to understand these user-interface tools without knowing something about the data transformation that products including BW use to first filter and organize the data, both important steps in SAP data management.
Separating the layers can invite trouble by masking data-integrity issues, which argues for a seamless, integrated approach that gives users the power to fix problems on the spot. In an age increasingly characterized by self-service, SAP data management may call for a more integrated technology stack than SAP is ready to provide.
