Yashi,
Either you can built a Universe through IDT and consume the relationship between the database and the reports. IDt act as the semantic layer between the db and bo reports. you can design the IDT through the query executed in HANA. Once the design is made, the reports can retrieve the universe to produce a relational tables. All the data are loaded in form of microcubes, which in turn helps in aggregation /calculations,drill and filtering of Columns within BO reports.
To view the summary reports in mobile, you can use the BO explorer
