Explore the power of Datomic, an append-only database, in this 49-minute conference talk by Christian Johansen at NDC Conferences. Discover how Johansen combined his passions for technology and food by building an application around 7 years of meal plan data. Learn about Datomic's unique features, including its RDF-like schema approach, speed, and Prolog-inspired query language. Gain insights into the practical application of Datomic through examples from Johansen's project. Additionally, explore Datascript, which brings Datomic's APIs to the browser, enabling real-time browser UIs without traditional REST APIs. Delve into topics such as Datomic's data model, transaction history, speculative changes, and the integration of Datascript for enhanced client-side functionality.
