🌳2) Structure of Real Estate System

This architecture visually represents the various functions and modules necessary for real estate transactions, management, and operations. The system architecture primarily illustrates data flow, interaction between functionalities, and the user interface, providing an overview of the entire real estate system’s operation.

1] User Interface Layer

• Users: The main users of the real estate system include property owners, buyers, tenants, agents, and managers.

• Web/Mobile Applications: Users can access the system via a web browser or mobile app to search listings, create contracts, or conduct transactions.

• Dashboard: Administrators or agents can manage listings, track transactions, and generate reports through an operational dashboard.

2] Business Logic Layer

• Listing Management: A module for registering, modifying, and deleting property listings, managing details such as location, price, size, and property type.

• Transaction Management: Functions for tracking and managing all transactions related to purchasing, leasing, and selling properties. This includes contract creation, payment verification, and signature procedures.

• Lease Management: A system for automatically managing lease agreements and rent collection, tracking contract fulfillment between landlords and tenants, and setting up automated notifications.

• Customer Relationship Management (CRM): A module for managing customer information, transaction history, and communications, allowing for the analysis of customer data to develop marketing and sales strategies.

• Analytics and Reporting: Functions to analyze real-time data on listings, transaction status, and market trends to generate reports.

3] Data Layer

• Real Estate Database: A central database storing all real estate-related data, including listing information, transaction records, and user data, which is referenced and used throughout the system.

• Transaction History Records: Records of all transactions, with blockchain technology available to enhance transparency and security.

• Customer Database: A database for storing customer information, transaction history, and listings of interest, integrated with the CRM module.

4] External System Integration Layer

• Blockchain: Blockchain technology is used to enhance the transparency and security of real estate transactions, allowing for transaction records and ownership verification. For example, real estate sales or lease agreements can be managed as NFTs.

• Financial System Integration: Links to banks or payment gateways to support fund transfers, loan processing, and rent payments related to real estate transactions.

• Government and Legal System Integration: The real estate system connects to government public data systems to provide real-time information such as title deeds, publicly assessed land values, and relevant legal documents.

• Mapping and Location Services: Integrated with map APIs (e.g., Google Maps) to provide visual location data for properties.

5] Security Layer

• Authentication and Authorization Management: A user authentication system to manage logins, authorization, and data access controls, granting appropriate permissions to administrators, agents, buyers, and tenants.

• Data Encryption: Encryption technology is applied to protect user information and transaction data, ensuring data integrity.

• Audit Logs: Logs of all user activities and transaction records are kept to improve system security and enable tracking in case of issues.

6] API and Integration Layer

• Internal and External APIs: APIs facilitate smooth communication between internal modules within the real estate system and support integration with external systems (financial, blockchain, mapping services).

• Module Integration: Ensures interaction between various system modules (listing management, transaction management, lease management) for comprehensive system functionality.
