Both sides like to tweak each other. Both like to harangue customers for new revenue. Customers however fume that stuff they have paying maintenance for years cannot seem to get much attention.
So I was pleased when reader Tan Ah Beng pointed out this presentation about SAP support for various Oracle database versions (including the in-memory switch in 12c) and Engineered Systems. I am sure there is similar for IBM DB2 and Microsoft SQL Server, and for SAP’s own Sybase and MaxDB products.
SAP says 6.000+ customers are now using HANA is some form. Which means the majority of its 270,000 are still on the other databases. Many will continue to survive for years as customers have elaborate systems management and staff infrastructures built around them.
With that disproportionate mix, wish those databases would get even a fraction of the public love HANA gets from SAP. And a commitment from SAP and the database vendors they will continue to get plenty of maintenance dollars towards the "junction" where their products intersect.
