Architecture

The Address Details app is built using a modern, service-oriented architecture that provides reliable integration between Business Central and external data sources. This document outlines the technical architecture, data flow, and key components.

Architecture Overview

The application follows a three-tier architecture pattern:

1. Presentation Layer - User interface components within Business Central
2. Business Logic Layer - Core application logic and data processing
3. Data Access Layer - Integration with external APIs and data storage

Core Components

Application Layer

Codeunits

• Address Management (QTEAMAddressMgt) - Core address processing logic
• BAG Functions (QTEAMBAGFunctions) - API data extraction and mapping
• BAG Update Manager (QTEAMBAGUpdateFromAPI) - Orchestrates data synchronization
• Address Setup (QTEAMAddressSetup) - Installation and configuration logic
• Error Handling (QTEAMErrorHandling) - Centralized error management

Data Storage

• BAG Building Table - Building information storage
• BAG Residence Table - Residence data management
• BAG Setup Table - Configuration and API settings
• Address Details Setup - Application configuration parameters

User Interface

• Setup Pages - Configuration and administration interfaces
• Address Cards - Display address and building information
• Building Lists - Browse and search building data
• Map Integration - Google Maps visualization components

Integration Layer

BAG Registry API

• REST API Integration - Direct connection to Dutch BAG services
• JSON Data Processing - Parse and transform API responses
• Real-time Lookup - On-demand address and building data retrieval
• Bulk Data Import - Large-scale data synchronization capabilities

Google Maps API

• Geocoding Services - Address to coordinate conversion
• Map Display - Interactive map components
• Address Validation - Location verification services
• Reverse Geocoding - Coordinate to address conversion

Power Automate Integration

• Webhook Endpoints - Automated data import triggers
• Flow Integration - Custom workflow automation
• Event-driven Processing - Real-time data updates
• External System Connectivity - Connect with third-party applications

Data Flow Architecture

Address Lookup Process

1. User initiates address search in Business Central
2. Application validates input parameters
3. API request sent to BAG registry
4. Response data processed and mapped to internal structures
5. Results displayed in Business Central interface
6. Optional: Data cached for future use

Building Data Synchronization

1. Automated or manual sync process initiated
2. API credentials and endpoints validated
3. Bulk data requests sent to BAG services
4. Response data processed in batches
5. Local database updated with new information
6. Synchronization status and errors logged

Google Maps Integration

1. Address or coordinates provided as input
2. Google Maps API called for mapping services
3. Map data and geocoding results obtained
4. Interactive map displayed in Business Central
5. User interactions captured and processed

Security Architecture

Authentication and Authorization

• API Key Management - Secure storage of external API credentials
• Business Central Permissions - Role-based access control
• Entitlement Management - License-based feature access
• Data Encryption - Secure transmission and storage protocols

Permission Structure

• Essential Tier - Basic address lookup and validation
• Premium Tier - Advanced features and bulk operations
• Administrative Access - Setup and configuration capabilities
• Read-only Access - Data viewing without modification rights

Performance Architecture

Caching Strategy

• Local Data Storage - Frequently accessed data cached locally
• API Rate Limiting - Intelligent request throttling
• Batch Processing - Efficient bulk data operations
• Lazy Loading - On-demand data retrieval

Scalability Features

• Asynchronous Processing - Non-blocking API calls
• Background Jobs - Large operations handled offline
• Connection Pooling - Efficient API connection management
• Error Retry Logic - Automatic recovery from transient failures

Deployment Architecture

Business Central Integration

• AL Language - Native Business Central development
• Extension Package - Standard app deployment model
• Dependency Management - Required Q-Team components
• Version Compatibility - Support for current BC versions

Environment Support

• SaaS Deployment - Cloud-hosted Business Central instances
• On-Premises - Local Business Central installations
• Hybrid Scenarios - Mixed cloud and on-premises environments
• Multi-tenant - Shared service configurations

Extension Architecture

Extensibility Points

• Event Publishers - Custom integration points
• Interface Patterns - Standardized extension methods
• Configuration Tables - Customizable settings
• Custom Fields - Additional data storage options

Integration Patterns

• Standard APIs - RESTful web services
• Webhook Support - Event-driven external integration
• File Import/Export - Batch data exchange capabilities
• Custom Connectors - Third-party system integration

Monitoring and Diagnostics

Logging Framework

• Application Logs - Detailed operation tracking
• API Call Logging - External service interaction records
• Error Tracking - Comprehensive error information
• Performance Metrics - System performance monitoring

Health Monitoring

• API Connectivity - External service availability checks
• Data Quality - Validation and consistency monitoring
• System Resources - Performance and resource utilization
• User Activity - Usage patterns and analytics

This architecture ensures reliable, scalable, and maintainable address data management within the Business Central environment while providing seamless integration with external data sources and services.
