In most of the companies, we observe the following challenges :

  • Information workers want access to all relevant data sources, wherever the information is located (externally or internally). The data may be in different form: raw data (e.g. database tables, spreadsheets) or aggregated data in the form of data analytics (e.g. charts, reports, dashboards).
  • Information workers want easy ways to reuse existing Business Intelligence (BI) content:  it is always simpler and faster to reuse existing content rather than starting from scratch. However, current BI solutions make this difficult for a non-technical user. 
  • Information workers want to be self-sufficient and make faster decisions. Current BI solutions still require technical experts for many tasks.  For example, the task of connecting to and modelling new data sources or customizing reports or dashboards need the help of an expert.

/wp-content/uploads/2012/11/remix_161003.pngis a self-service BI application that allows business users to easily reuse and combine analytics. The application enables mashups of enterprise and external data/analytics. Business users are able to share their analytics allowing other users to quickly build new analytics. Business users do not write queries but simply graphically manipulate data and analytics in a single user interface. It’s a direct and intuitive way to build and reuse analytics without requiring the user to understand IT concepts.

In the following demo, remix capabilities are illustrated with a healthcare scenario. The hospital is running SAP IS-H and the ERP data is automatically synchronized with HANA.
Two doctors, Doctor House and Doctor Cuddy, share and combine any internal or external analytics with remix in order to solve a medical problem. The application offers them different ways to combine analytics: it is possible to append data from one analytic to another. The resulting analytic will keep the same visualization but the two data sets will be concatenated. They can also replace the data of an analytic by another data set while keeping the original visualization. Finally, they can overlay two analytics that share common dimensions such as time or geography.
This demo was finalist in the 2012 TechEd DemoJam in Madrid.
Demo is available on YouTube:
Our solution is built on SAP Netweaver Cloud, making the application suitable for cloud or on-premise deployment. For scalability, mashups are performed in SAP HANA DB, leveraging the in-memory calculation engine. Finally, the solution is built as a web application, working on desktop and mobile browsers (targeted to chrome/desktop and safari/ipad) using HTML5 and SAP UI5.
