However, I didn't mean the end of life of the database, because the Hana platform is still needed for the S\/4 release. What I meant is the fact that no one gets bright eyes, an excited voice or a rising pulse anymore when Hana is mentioned. <\/p>\n\n\n\n<p>A recent survey from Switzerland shows that about 40 percent of existing customers have already switched to Hana. However, the enthusiasm for this in-memory computing innovation from Professor Hasso Plattner is modest, resulting in my observation: Everybody loves Hana (inevitably), but nobody wants to marry it! The quantum physicist would now say that Hana is in a superposition - in a superposition state between alive and dead. <\/p><div id=\"great-376476156\" class=\"great-fullsize-content-en\" style=\"margin-bottom: 20px;\"><a data-no-instant=\"1\" href=\"https:\/\/www.youtube.com\/watch?v=6yfv7eho3Gc\" rel=\"noopener\" class=\"a2t-link\" target=\"_blank\" aria-label=\"Fullsize\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150.jpg\" alt=\"Fullsize\"  srcset=\"https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150.jpg 1200w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-400x50.jpg 400w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-768x96.jpg 768w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-100x13.jpg 100w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-480x60.jpg 480w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-640x80.jpg 640w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-720x90.jpg 720w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-960x120.jpg 960w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-1168x146.jpg 1168w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-18x2.jpg 18w, https:\/\/e3mag.com\/wp-content\/uploads\/2026\/03\/banner_26_04_08_1200x150-600x75.jpg 600w\" sizes=\"(max-width: 1200px) 100vw, 1200px\" width=\"1200\" height=\"150\"  style=\" max-width: 100%; height: auto;\" \/><\/a><\/div>\n\n\n\n<p>As long as the box with the cat from Schr\u00f6dinger's thought experiment is not opened, the cat is 50 percent dead and 50 percent alive. We have not yet measured whether Hana has a chance of survival. We have not opened the box yet! <\/p>\n\n\n\n<p>Of course, the poor cat can take only one of both states and cannot have several states at the same time like a quantum object, see double-slit experiment. In real life there is no superposition like in quantum physics. <\/p>\n\n\n\n<p>Schr\u00f6dinger's cat is not animal torture, but remains a thought experiment. With the missing Hana roadmap, however, SAP torments its existing customers, who live in a kind of superposition: They have to pay license fees for AnyDB and Hana at the same time during the release upgrade. Thus, the ERP system to be transformed has two states: AnyDB and Hana, see double column experiment again!<\/p>","protected":false},"excerpt":{"rendered":"<p>Vor einigen Wochen schrieb ich in einem Kommentar: Hana ist tot.
