• Database Branching - Creates isolated database branches to prototype schema modifications without impacting production data.
• Migration Generation - Generates interactive, step-by-step migration scripts by comparing local schema definitions against the current database state.
• Object-Relational Mapping Associations - Connects object types to one another with configurable cardinality and exclusivity to model relational associations.
• Schema Migrations - Transforms existing records during schema updates using expressions to ensure data compatibility.
• Self-Hosted Deployment Solutions - Provisions and hosts database environments across major cloud platforms or via containerized self-hosting solutions.
• Large Language Model Connectors - Connects external AI providers to database records for retrieval-augmented generation workflows.
• Connection Pooling - Maintains a pool of active connections to optimize resource usage and handle multiple concurrent requests efficiently.
• Custom Data Types - Creates custom data types by adding constraints or annotations to existing scalars to enforce specific business logic or validation.
• Enumeration Types - Restricts properties to a predefined set of allowed values to ensure data consistency and simplify filtering operations.
• Data Querying Interfaces - Retrieves hierarchical data structures and related objects in a single query by specifying the desired result shape.

• Database Lifecycle Management - Creates and manages local database environments by handling installation, version selection, and lifecycle operations.
• Abstract Data Types - Creates reusable schema definitions that bundle common properties and behaviors for inheritance by multiple object types.
• Backup & Recovery - Reverts local database instances to previous states using automatically generated backups to recover from accidental or destructive modifications.
• Database Operations - Controls project environments, schema migrations, and database instances through a command-line interface for development and production workflows.
• Expression Indexes - Optimizes query performance by indexing the results of expressions and functions directly within the database.
• Pagination - Navigates large datasets using conditional filtering and offset-based cursors for performant retrieval.
