Kotlin SQL Framework
Features
- SQL Frameworks - Provides a type-safe SQL DSL and lightweight DAO for database access across multiple engines.
- Kotlin SQL Compilers - Compiles Kotlin DSL expressions into SQL query trees at compile time for type safety.
- DDL Generators - Generates and executes DDL statements from Kotlin table definitions to keep schemas in sync.
- Kotlin Schema Definitions - Defines and evolves database schemas programmatically in Kotlin, keeping tables in sync with code.
- Database Transaction Managers - Wraps database operations in explicit transaction blocks that manage connection lifecycle and rollback.
- Multi-Database Connections - Connects to multiple database engines using standard JDBC and R2DBC drivers for portable development.
- SQL Database Engine Support - Connects to various database engines via JDBC and R2DBC drivers for portable development.
- Table Definitions - Declares database tables as typed objects with columns, keys, and indexes mirroring relational structure.
- Abstraction Layers - Provides a unified abstraction over JDBC and R2DBC drivers for database-agnostic connectivity.
- Entity Proxy - Defers loading of related entity references using proxy objects that trigger queries on demand.
- SQL Query Extensions - Provides a type-safe Kotlin DSL for building and executing SQL queries with compile-time safety.
- Ruby DSL Query Compositions - Builds and executes SQL queries using a type-safe DSL that maps table schemas to typed objects.
- Lazy-Loading Repositories - Maps database rows to entity objects with lazy-loaded references and repository-style CRUD operations.
- Kotlin DAO Frameworks - Provides a lightweight DAO framework for Kotlin with lazy loading and repository-style CRUD operations.
- Kotlin DAO Layers - Provides a data access layer that maps rows to entity objects with lazy-loaded references and CRUD operations.
- Compile-Time Mappings - Maps database columns to Kotlin properties using compile-time code generation for performance.
- Kotlin Schema Migrations - Manages database schemas programmatically in Kotlin code with transactional lifecycle operations.
- Programmatic Schema Forge Tools - Creates and drops schema objects programmatically within transactions to synchronize with code definitions.
- Database Column Encryption - Implements client-side column encryption that automatically encrypts and decrypts database fields.
- Database & ORM Tools - Kotlin SQL Framework
- Kotlin Libraries - Kotlin SQL Framework
