OElite.Data

Core data access layer: generic repository, DbCentre base, and MongoDB integration primitives for OElite applications.

Overview

OElite.Data provides the foundational data access patterns for OElite applications. It defines the DataRepository<T> generic repository, the DbCentre base class for MongoDB-backed data centres, and the IDataRepository contract that all repositories implement.

This package is consumed by both the OElite.Common.Hosting services layer (for dependency injection wiring) and by every application-specific repository that extends DataRepository<T> to add entity-specific queries.

Features

📚 Repository Pattern

• DataRepository<T>: Generic repository base class providing standard CRUD operations
• IDataRepository: Interface contract for all repositories (enables mocking and substitution)
• Type-safe entity operations with async/await throughout

🗄️ DbCentre Base

• MongoDB Integration: Base class for MongoDB-backed data centres
• Connection lifecycle management
• Collection accessor utilities
• Logging integration with IAppConfig

🔌 Extensibility

• Subclassable for application-specific repositories
• Supports custom query methods per entity type
• Compatible with OElite.Restme.MongoDb for advanced MongoDB features

Quick Start

1. Installation

dotnet add package OElite.Data

2. Define a Custom Repository

using OElite.Data;
using OElite.Restme.Utils;

public class ProductRepository : DataRepository<Product>
{
    public ProductRepository(DbCentre dbCentre) : base(dbCentre) { }

    public Task<List<Product>> GetByCategoryAsync(string categoryId)
    {
        return FindAsync(p => p.CategoryId == categoryId);
    }
}

Dependencies

• OElite.Restme 2.x (MongoDB driver, IRestme provider)
• OElite.Restme.Utils 2.x (BaseEntity, attributes)
