Anekdoten aus dem wahren Leben im Umgang mit fehlenden Werten: taktisch, manipulativ, ignorant, professionell, oder gar blitzschnell… Bevor die Menschheit mit Aufzeichnungen durch Chroniken und Messungen begonnen hat, gab es nur subjektive Informationen über Menschen, Natur und Gesellschaft. Objektive Informationen in der heutigen Form von Datentabellen fehlten vollkommen und sind auch nicht überliefert. Erst mit dem Aufkommen erster Symbol- und Schriftsprachen ca. 3500 Jahre v.

Feed: Planet PostgreSQL. © Laurenz Albe 2021Customers have often asked me what I think of “Entity-attribute-value” (EAV) design. So I thought it would be a good idea to lay down my opinion in writing.What is entity-attribute-value design?The idea is not to create a table for each entity in the application.
