ReadonlyDb

In-memory readonly database access — snapshots, code generation, and live runtime mirroring.

Rmp.ReadonlyDb

v2026.3.6

A modular suite for reading database data into strongly-typed, in-memory IQueryable collections. Whether you need offline snapshots, generated C# code with embedded data, or a live-refreshing mirror — ReadonlyDb eliminates boilerplate and delivers blazing-fast readonly access.

4 packages — modular, install only what you need
SQL/PG SQL Server & PostgreSQL — dual database support
.NET 8.0 modern target framework

Rmp.ReadonlyDb.Core

Core abstractions for readonly database access: schema discovery, lazy entity sets, and IQueryable in-memory projections.

IReadonlyDbContext & IReadonlyEntitySet<T> interfaces
Thread-safe lazy loading with LazyEntitySet<T>
Cached reflection-based entity mapping
SQL Server & PostgreSQL schema introspection
JSON snapshot serialization

Rmp.ReadonlyDb.Snapshot

Offline snapshot provider — reads a database once and creates in-memory IQueryable/List representations with lazy loading.

SnapshotDbContext — full DB-to-memory capture
FileSnapshotDbContext — load from JSON files (no DB needed)
Export to JSON via ExportToJsonAsync()
Dynamic access by table name

Rmp.ReadonlyDb.CodeGen

Code generation provider — reads a database offline and generates compilable C# source files: POCOs, static datasets, and a typed DbContext.

Generates compilable C# POCO entity classes
Static ReadonlyDataContext with Lazy<> collections
Embedded row data as static initializers
FK-based navigation property generation
Configurable MaxRowsPerTable safety limit

Rmp.ReadonlyDb.Runtime

Runtime provider — connects to a live database, mirrors data into an in-memory store with optional dump-to-file, lazy loading, and periodic refresh.

RuntimeDbContext — live DB → in-memory mirror
Auto-dump to files after loading
PreferDumpOverLive — skip DB if dump files exist
RefreshInterval — periodic data refresh
Full LINQ support on in-memory data

GraphOrm

Eliminate N+1 queries and cartesian explosions with SQL JSON aggregation

Rmp.GraphOrm

v1.0.0

GraphOrm eliminates the classic problems of object-graph loading — N+1 queries and row duplication from JOINs — by leveraging SQL JSON aggregation (FOR JSON PATH in SQL Server, json_agg in PostgreSQL). Attribute-based mapping, a fluent query builder, and LINQ expression support make it a natural complement to any ORM or raw ADO.NET workflow.
