What problem does it solve?

Developers struggle with vendor lock-in and complex code changes when switching or integrating multiple data providers (SQL, NoSQL, Vector). This Skill eliminates that complexity, allowing a single codebase to work across diverse data stores.

Core Features & Use Cases

• Provider Transparency: Write entity code once, run it on PostgreSQL, MongoDB, SQLite, Redis, Weaviate, or JSON stores without code changes.
• Capability Detection: Dynamically check what features (LINQ, transactions, fast remove) a provider supports and implement graceful fallbacks.
• Context Routing: Isolate data logically using partitions (multi-tenancy, archives) or route to different physical sources (read replicas, caches).
• Use Case: Easily switch your application from a local SQLite database to a production PostgreSQL cluster, or integrate a Redis cache and a Weaviate vector database, all without rewriting your core data access logic.

Quick Start

To check if your current data provider supports LINQ queries for the 'Todo' entity, use: var capabilities = Data<Todo, string>.QueryCaps; if (capabilities.Capabilities.HasFlag(QueryCapabilities.LinqQueries)) { /* use LINQ / } else { / client-side filter */ }
