WDL is a platform for designing, visualizing, and documenting database structures. It enables you to model tables and their attributes, define primary and foreign keys, establish relationships between entities, and build a complete ER schema before implementing the database.
Client :: Visual Database Designer: interactive ER diagrams, table and relationship editing, schema navigation, PostgreSQL DDL export and account management.
Core :: Database Modeling API: realm and project management, relational schema metadata, table and column definitions, constraints, indexes, relationships and diagram layout persistence.
Identity :: Authentication & Account Management: user registration, account profiles, OAuth2 token issuance, JWT authentication, refresh token rotation, session management and revocation.
Infrastructure :: Platform Services & Audit Pipeline: PostgreSQL, Redis, Kafka, Debezium CDC, ClickHouse audit analytics and MinIO cold storage orchestrated with Docker Compose.
Shared :: API Contracts & Schemas: reusable Pydantic models, request and response contracts, shared enumerations and consistent data validation across WDL services.
