MemberJunction Project Overview

Introduction

MemberJunction is an open-source platform designed to help organizations efficiently manage data, build applications, and leverage AI for better insights. It provides a comprehensive set of tools for handling records, generating reports, creating dashboards, and includes an AI assistant named Skip that helps users interact with their data using natural language.

Core Architecture

MemberJunction is built on a modern, metadata-driven architecture that combines powerful business logic capabilities with flexible customization options. The platform is designed around these key architectural principles:

Metadata-Driven Design

At the heart of MemberJunction is a metadata-driven approach where the structure of entities, fields, relationships, and UI components is defined in metadata. This enables:

Rapid application development
Dynamic customization without code changes
Consistent user experience
Simplified maintenance and upgrades

Provider Architecture

MemberJunction uses a provider architecture that abstracts implementation details:

Data Providers: Abstract database access
Authentication Providers: Support multiple authentication methods
Storage Providers: Handle file storage and retrieval
LLM Providers: Integrate with AI language models

This provider model allows for flexibility in implementation and makes it easier to extend the platform for specific needs.

Business Logic Layer

The business logic layer in MemberJunction:

Enforces data integrity and validation
Implements business rules and workflows
Manages calculated fields and derived data
Handles complex operations across entities

GraphQL API

MemberJunction uses GraphQL as its API layer, which:

Provides a flexible query language for clients
Allows clients to request exactly the data they need
Reduces over-fetching and under-fetching of data
Supports complex queries across related entities

Key Components

MemberJunction consists of several key components that work together to form a complete platform:

MemberJunction Explorer

The main user interface for navigating and working with data. Features include:

Global search functionality
Record management
Reporting and dashboards
View creation and management
AI-assisted interactions through Skip

CodeGen System

Automatically generates TypeScript code based on metadata:

Generates strongly typed entity classes
Creates service classes for API interactions
Builds GraphQL schemas and resolvers
Produces UI components based on metadata

Database Layer

The database layer handles data storage and retrieval:

Supports SQL Server and Azure SQL Database
Uses a flexible provider model for database access
Includes features for data migration and schema updates
Supports full-text search and indexing
