The only complexity I find with the product is the programming language; people find it harder, but once you know the language, it's not that difficult. Regarding the future of SAP Business Warehouse, I would to see added features that simplify the product very well now. They are coming up with a terminology called SAP BDC where they are consolidating their tools, SAP Data Sphere for integration and SAP BW for the ETL and warehousing parts, and SAP Analytics Cloud. They are packaging these three features and calling it Business Data Cloud; they are fully coming on the cloud. We have to wait and watch; they have been speaking about BW/4HANA for quite some time now, but the customers or clients I work with are not finding great interest and it was seen as a candidate for evaluation. I have seen people looking at the latest technologies who are already on cloud who started building from scratch on cloud, such as Snowflake or Databricks, which can process very huge amounts of data and also address unstructured data, where SAP lags behind in cases where there is a need to bring in unstructured data. I have worked with SAP Data Intelligence, which earlier used to be called SAP Data Hub. The unstructured data is not greatly handled in SAP at this point in time.
