Using the Exposed SQL Framework to Manage Your Database
0 likes52 views
The document discusses using the Exposed SQL framework to manage databases in Kotlin. It introduces Exposed as an open source SQL framework made by JetBrains that supports PostgreSQL, SQLite, Oracle, SQL Server and H2. Exposed provides two levels of database access - a DSL for type-safe SQL and DAOs for lightweight data objects. It demonstrates defining database schemas, connecting to databases, interacting with tables using the DSL and DAO, and building relationships between tables.
