OrpheusORM

OrpheusORM is a module-oriented ORM with built-in schema evolution for .NET — supporting SQL Server, MySQL, and PostgreSQL with full async API, connection pooling, and aggregate-level persistence via the unique Module system.

CI Build

Highlights

  • Async API — full async support across all I/O methods with CancellationToken
  • Connection Pooling — native ADO.NET connection pooling via IOrpheusConnectionFactory
  • PostgreSQL Support — new DDL helper backed by Npgsql
  • Modern DI — constructor injection replaces the static ServiceManager pattern
  • Batched Insert/Update/Delete — Save() sends fewer, larger round trips instead of one per row (tune via IOrpheusTable.BatchSize)
  • Performance — cached model metadata + IDisposable implementations throughout

Overview

Schema creation

OrpheusORM has a built-in schema engine, which you can optionally use to create and/or update your schema, based on your model classes.

Model binding

By default Orpheus assumes that your table names will match your model class names. You can override this with the [TableName] attribute.

Nested data

Using an OrpheusModule you can save nested data (master-detail-subdetail) with just one Save. All master-detail relationships and keys are updated automatically.
