R/2 Mainframe Solution
R/2 is SAP AG mainframe software that runs on IBM, Siemens, Amdahl, and compatible equipment. This type of solution cannot claim to be open, although with the help of Application Link Enabled (ALE) technology, R/2 can be linked to R/3 systems and share online data.
Nevertheless, and despite the emergence of new technologies and the significant decrease of hardware prices, some companies some companies preferred the approach of the mainframe solution. This is mainly targeted at enterprises with data?intensive and centralized industries.
R/2 is the antecedent of the client/server R/3 system and also offers comprehensive, fully functional business applications to satisfy the demands of mainframe users. SAP will still continue to support R/2 systems till the year 2004, and so it is advising customers to migrate to R/3.
