Hard disk drives are mechanical devices, requiring a rotating magnetized platter that stores binary data, and a read/write head that accesses and reads that data. Reading, writing, and searching using HDD are an inherent bottleneck to any classical database. The principle drawback of a classical database is the fact that it uses HDDs. Using INSERTS, READS, UPDATES and QUERIES, the database allows users to persist, retrieve, and manage data on demand. A DMBS manages an array of HDDs that store data in a row based format. Let’s begin our over overview of SAP HANA by contrasting it to the traditional DBMS.Īs a refresher, lets recall how a classical database works. While HANA can perform any and all features of a traditional DBMS, it also provides many benefits that a classical database server does not.

While HANA serves as a replacement for classical hard disk based storage systems, it should be understood that it is more than just a replacement. The SAP HANA Acronym stands for ( High-performance ANalytic Appliance). SAP HANA is a platform that serves to replace the classical hard disk based data storage system with an in-memory alternative. What exactly is SAP HANA? How is it able to bring such dramatic improvements to our programs? And finally, how will switching over to SAP HANA impact me as an ABAP developer? SAP HANA Overview on a Technical Level What we would like to know is not the what, but the how. This all sounds wonderful, but technical folks understand that nothing works by magic. You’ve probably heard that it’s “the future” and a “game changer.” You’ve also probably heard that it’s much faster, and it can take tasks that require hours and finish them in minutes.
