Database Schema

Main Tables

Extension Configuration Table

  • Table ID: 50100
  • Fields:
    • Code (Code[20])
    • Description (Text[100])
    • Value (Text[250])
    • Type (Option: Text, Integer, Boolean)

API Endpoints

REST API

Base URL: /api/walter75/v1.0/

Endpoint Method Description
/config GET Retrieve configuration settings
/config POST Update configuration settings
/transactions GET Retrieve transaction logs
/status GET Get system status

Security Considerations

Important

All API calls must be authenticated using OAuth 2.0 or API keys.

Permission Sets

  • W75-ADMIN - Full administrative access
  • W75-USER - Standard user access
  • W75-READ - Read-only access
  • W75-CONFIG - Configuration management

Performance Guidelines

Optimization Best Practices

  1. Batch Processing

    • Process records in batches of 100-500
    • Use commit after each batch
    • Implement progress indicators

  2. Caching

    • Cache frequently accessed configuration data
    • Invalidate cache on configuration changes
    • Use in-memory caching for session data

  3. Query Optimization

    • Use appropriate keys and filters
    • Avoid unnecessary table scans
    • Implement pagination for large datasets

Integration Patterns

Synchronous Integration

procedure SyncIntegration(RecordRef: RecordRef): Boolean
var
    HttpClient: HttpClient;
    Response: HttpResponseMessage;
begin
    // Implementation
    exit(Response.IsSuccessStatusCode);
end;

Asynchronous Integration

procedure AsyncIntegration(RecordRef: RecordRef)
var
    JobQueueEntry: Record "Job Queue Entry";
begin
    // Queue for background processing
    JobQueueEntry.ScheduleJobQueueEntry();
end;

Development Guidelines

Coding Standards

  • Follow AL coding conventions
  • Use meaningful variable and function names
  • Implement error handling
  • Add inline documentation

Testing Requirements

  • Unit tests for all business logic
  • Integration tests for API endpoints
  • Performance tests for batch operations
  • User acceptance testing

    • Version control commit

  2. Staging

    • Deploy to staging environment
    • Run automated tests
    • User acceptance testing

  3. Production

    • Schedule maintenance window
    • Deploy to production
    • Verify deployment
