History of SAP
In 2011 SAP launched HANA, an in-memory database that collapsed the old split between transactional and analytical systems.
- The early products were named for their architecture.
- Through the 2000s SAP wrapped R/3 into mySAP and then SAP ERP (ECC), part of the broader Business Suite, and built the NetWeaver…
- That idea, packaged software for enterprise processes, became the ERP industry, and SAP has led it ever since.
- Watch out: Assuming SAP is new, its depth reflects 50+ years of enterprise experience.
From R/1 to R/3
The early products were named for their architecture. R/1 was a single-tier financial system; R/2 was a mainframe, two-tier system that added integrated modules. The breakthrough was R/3 in 1992, a three-tier client-server architecture (presentation, application, database) that ran on standard hardware and could scale across large enterprises. R/3 made SAP the global standard for ERP.
The move to a suite and the web
Through the 2000s SAP wrapped R/3 into mySAP and then SAP ERP (ECC), part of the broader Business Suite, and built the NetWeaver technology platform to web-enable and integrate it. This era added CRM, SRM, SCM and BW alongside the ERP core.
The HANA and S/4HANA era
In 2011 SAP launched HANA, an in-memory database that collapsed the old split between transactional and analytical systems. In 2015 it released S/4HANA, a next-generation suite rebuilt on HANA with a simplified data model and the Fiori UX. This is the platform SAP is steering all customers toward, with cloud editions increasingly central.
Common pitfalls
- Assuming SAP is new, its depth reflects 50+ years of enterprise experience.
- Ignoring the R/3 heritage, its three-tier model still underpins how systems are structured.
- Missing the HANA turning point, it reshaped the whole product line.
