Hi All,

 

SAP HANA database stores the data in columnar format. So from row based table perspective, each column will be treated as an individual table with distinct values.

   

How HANA database maintains the relationship of each row so the user gets correct data? In other words, how HANA database internally process the column based records?

 

Regards,

Mandar
