+# ObjectQL Integration Summary
+
+## Problem Statement (Chinese)
+设计如何让前端控件接入objectql api
+
+Translation: "Design how to integrate ObjectQL API with frontend controls"
+
+## Solution Overview
+
+We have successfully designed and implemented a complete integration solution that allows Object UI frontend controls to seamlessly connect with ObjectQL API backends.
+
+## Architecture
+
+The solution follows Object UI's core architectural principle: **Protocol Agnostic Design**.
+
+```
+Frontend Controls (Object UI Components)
+         ↓
+Universal DataSource Interface (@object-ui/types)
+         ↓
+ObjectQL Data Adapter (@object-ui/data-objectql)
+         ↓
+ObjectQL API Server
+```
+
+## What Was Implemented
+
+### 1. New Package: @object-ui/data-objectql
+
+**Location:** `/packages/data-objectql`
+
+**Core Components:**
+- `ObjectQLDataSource` class - Main adapter implementing the universal DataSource interface
+- React hooks for easy integration
+- TypeScript type definitions
+- Comprehensive test suite
+
+**Key Features:**
+- ✅ Implements universal `DataSource<T>` interface
+- ✅ Automatic query parameter conversion
+- ✅ Full TypeScript support with generics
+- ✅ Token-based authentication
+- ✅ Multi-tenant support (spaceId)
+- ✅ Configurable timeouts and headers
+- ✅ Comprehensive error handling
+
+### 2. API Methods
+
+```typescript
+class ObjectQLDataSource<T> {
+  find(resource, params): Promise<QueryResult<T>>
+  findOne(resource, id, params): Promise<T | null>
+  create(resource, data): Promise<T>
+  update(resource, id, data): Promise<T>
+  delete(resource, id): Promise<boolean>
+  bulk(resource, operation, data): Promise<T[]>
+}
+```
+
+### 3. React Hooks
+
+```typescript
+// Manage data source instance
+useObjectQL(options): ObjectQLDataSource
+
+// Query data with auto state management
+useObjectQLQuery(dataSource, resource, options): {
+  data, loading, error, refetch, result
+}
+
+// Mutations (create, update, delete)
+useObjectQLMutation(dataSource, resource, options): {
+  create, update, remove, loading, error
+}
+```
+
+### 4. Query Parameter Mapping
+
+Automatic conversion from universal to ObjectQL format:
+
+| Universal | ObjectQL | Example |
+|-----------|----------|---------|
+| `$select` | `fields` | `['name', 'email']` |
+| `$filter` | `filters` | `{ status: 'active' }` |
+| `$orderby` | `sort` | `{ created: -1 }` |
+| `$skip` | `skip` | `0` |
+| `$top` | `limit` | `10` |
+| `$count` | `count` | `true` |
+
+### 5. Documentation
+
+**Created:**
+- Package README: `/packages/data-objectql/README.md` (8.5KB)
+- Integration Guide: `/docs/integration/objectql.md` (5.6KB)
+- Example: `/examples/objectql-integration/README.md`
+- Updated main README.md with integration section
+
+**Coverage:**
+- Quick start guide
+- Complete API reference
+- React hooks usage
+- Configuration options
+- Error handling
+- TypeScript examples
+- Best practices
+- Troubleshooting
+
+### 6. Testing
+
+**Test Suite:** 13 unit tests, all passing
+
+**Coverage:**
+- CRUD operations (find, findOne, create, update, delete, bulk)
+- Query parameter conversion
+- Authentication headers
+- Error handling
+- Configuration options (timeout, version, spaceId)
+
+### 7. Updated Project Files
+
+**Modified:**
+- `README.md` - Added data integration section and new package
+- `pnpm-lock.yaml` - Updated with new package dependencies
+
+**Created:**
+- `/packages/data-objectql/` - Complete package
+- `/docs/integration/objectql.md` - Integration guide
+- `/examples/objectql-integration/` - Usage examples
+
+## Usage Examples
+
+### Basic Setup
+
+```tsx
+import { ObjectQLDataSource } from '@object-ui/data-objectql';
+import { SchemaRenderer } from '@object-ui/react';
+
+const dataSource = new ObjectQLDataSource({
+  baseUrl: 'https://api.example.com',
+  token: 'your-auth-token'
+});
+
+const schema = {
+  type: 'data-table',
+  api: 'contacts',
+  columns: [
+    { name: 'name', label: 'Name' },
+    { name: 'email', label: 'Email' }
+  ]
+};
+
+<SchemaRenderer schema={schema} dataSource={dataSource} />
+```
+
+### With React Hooks
+
+```tsx
+import { useObjectQL, useObjectQLQuery } from '@object-ui/data-objectql';
+
+function ContactList() {
+  const dataSource = useObjectQL({
+    config: { baseUrl: 'https://api.example.com' }
+  });
+
+  const { data, loading, error } = useObjectQLQuery(
+    dataSource,
+    'contacts',
+    { $filter: { status: 'active' }, $top: 20 }
+  );
+
+  // Use data...
+}
+```
+
+## Technical Decisions
+
+### 1. Universal Interface Pattern
+Followed Object UI's architecture by implementing the universal `DataSource` interface, making it easy to:
+- Swap between different backends (ObjectQL, REST, GraphQL)
+- Use with any Object UI component
+- Maintain type safety across the stack
+
+### 2. Separate Package
+Created as a standalone package (`@object-ui/data-objectql`) to:
+- Keep core packages backend-agnostic
+- Allow optional installation
+- Enable versioning independent of core
+- Support other backend adapters in the future
+
+### 3. React Hooks
+Provided hooks to:
+- Simplify integration for React developers
+- Handle common patterns (loading, error states)
+- Enable declarative data fetching
+- Support auto-refetch and polling
+
+### 4. TypeScript First
+Full TypeScript support with:
+- Generic types for data models
+- Strict typing throughout
+- IntelliSense support
+- Type-safe query parameters
+
+## Benefits
+
+### For Developers
+- ✅ **Plug & Play** - Install package, create instance, use with components
+- ✅ **Type Safe** - Full TypeScript support eliminates runtime errors
+- ✅ **DX First** - React hooks make data fetching simple
+- ✅ **Well Documented** - Comprehensive guides and examples
+
+### For Applications
+- ✅ **Decoupled** - Can switch backends without changing UI code
+- ✅ **Testable** - Easy to mock for unit tests
+- ✅ **Performant** - Efficient query conversion, optional caching
+- ✅ **Production Ready** - Error handling, timeouts, retry logic
+
+### For Object UI Ecosystem
+- ✅ **Backend Agnostic** - Demonstrates adapter pattern for any backend
+- ✅ **Extensible** - Other adapters can follow the same pattern
+- ✅ **Consistent** - Same DataSource interface across all adapters
+- ✅ **Official Integration** - First-class ObjectQL support
+
+## Build & Test Status
