Explore the innovative Realm mobile database and object framework in this conference talk from Philly ETE 2016. Discover how Realm offers a powerful alternative to SQLite, allowing developers to work directly with objects instead of relational data. Learn about Realm's key features, including its object storage system, robust query capabilities, and efficient handling of relationships. Dive into practical examples of saving objects, performing transactions, and retrieving data using Realm's fluent interface. Understand how Realm addresses security concerns with built-in AES-256 encryption and tackles multi-threading challenges. Gain insights into Realm's async API, RxJava support, and its implementation as an MVCC database. By the end of this talk, grasp how Realm can streamline mobile app development by eliminating the need for SQL and complex object-relational mapping.
