> HANA is actually something originally created by professor SangKyun Cha in Korea and not a MaxDB
HANA is just a brand name, it consists of several software packages put together. MaxDB is the center piece as query and as database layer, but there is also P*TIME and TREX integrated. Only the P*TIME is from the Korea-Prof (see http://news.donga.com/Society/3/03/20120711/47677546/1 ).
"SAP HANA: a number of technologies were developed or acquired by SAP SE. These included TREX search engine (in-memory column-oriented search engine), P*TIME (in-memory OLTP Platform acquired by SAP in 2005), and MaxDB with its in-memory liveCache engine."
