1. Methodologies Used

The documentation employs the following industry-standard system modeling techniques to provide a complete and structured view of the real estate marketing process:

• B1 – Verbal Analysis
  A detailed, text-based description of the real estate marketing procedure, outlining all steps, actors, and decision points.

• B2 – Use Case Analysis (UML Use Cases)
  UML-based use case diagrams illustrating system functionality from the initial client request to the completion and logging of the transaction.

• B3 – Organizational Entities (OEs)
  Identification and analysis of organizational roles involved in the process, including:

  • Client
  • Real Estate Agent

• B4 – Functional Decomposition
  Breakdown of the overall system functionality into smaller, manageable sub-functions to clarify responsibilities and system behavior.

• B5 – Process Decomposition
  Decomposition of the real estate marketing workflow into sequential and interrelated processes, highlighting process flow and dependencies.

• B6 – IDEF3 Workflow Diagram
  Modeling of the operational workflow, focusing on process sequencing and execution logic.

• B7 – IDEF3 State Transition Diagram
  Representation of system state changes throughout the lifecycle of a real estate marketing request.

• B8 – Data Flow Diagram (DFD)
  Visualization of how data is generated, processed, stored, and transferred within the system.

• B9 – IDEF0 Diagram
  Functional modeling of the system, emphasizing:

  • Inputs (Client Identification, Property Information)
  • Outputs
  • Controls (Agency Policy, Legal Regulations)
  • Mechanisms (Property Database, Real Estate Agent)

• B10 – Entity Relationship (E–R) Model
  Conceptual data model defining entities, attributes, and relationships required to support the real estate marketing process.

2. The Marketing Process

The core system is based on the interaction between two primary entities:

• Client
• Real Estate Agent

The workflow includes the following key steps:

1. Client Request
   The process begins when a client requests professional real estate marketing services.

2. Identity & Property Validation
   The agent verifies the client’s identity and confirms property ownership and details.

3. Database Verification
   Existing records are checked to ensure consistency and eligibility.

4. Policy Compliance
   The request is evaluated against agency standards and legal requirements.

5. Finalization

   • If all checks succeed:
     • The transaction is logged
     • The marketing phase is initiated
   • Otherwise:
     • The request is rejected or returned for correction
