Real estate division

Real Estate Document Management

In production Standalone application

Manages documents for the group's real estate division, which operates through separate legal entities.

Problem

The real estate division needs a complete document record for each transaction, with a company structure and data model that differ from the automotive business. Its documents were managed in shared folders.

Solution

The system adapts the vehicle sales documentation application with its own company module and an independent database, keeping both operations' information separate.

Outcome

The real estate division manages its records in a separate database, with controls by legal entity and tracking for standard and monthly documents.

My role

I adapted the records system to the real estate model, designed the data separation, and built the company, access, and document modules.

How it works

Each transaction keeps its documents and data under the corresponding legal entity, with access and tracking in a separate database.
