Scalable Relational Database for Product Lifecycle Management

Design and implementation of a high-performance SQL database to unify product development, inventory, and sales data.

Client & Goal Overview

Client Type

Mid-sized Consumer Electronics Manufacturer (Retail & Manufacturing Sector)


Challenge

The client relied on siloed spreadsheets across departments, which created inconsistencies, duplicate entries, and frequent reporting delays. Expansion into e-commerce heightened the need for consolidated, real-time access to clean, structured data.


Our Role

We designed and implemented a robust SQL database architecture in PostgreSQL, following third normal form (3NF) principles. We led schema design workshops with stakeholders, developed stored procedures for data validations, and created views optimised for business reporting. Additionally, we provided training on query writing and performance optimisation.

Project Journey & Results

Project Scope
  • Designed a scalable relational database to support multi-brand inventory and order workflows across European retail locations.
  • Developed an Entity-Relationship model incorporating business rules and normalisation for data integrity.
  • Implemented stored procedures and triggers to enforce logic at the database level.
  • Delivered data access layers and optimised indexing strategies to support real-time reporting and BI integration.
  •  

Technical Stack
  • Database: PostgreSQL (AWS RDS hosted)
  • Data Modeling: Entity-Relationship Diagrams (ERD), 3NF normalization
  • ETL/ELT: Apache Airflow for orchestration, dbt for transformations
  • Languages: SQL, Python
  • Integrations: Power BI, legacy ERP connectors
  • Monitoring: pgAdmin, AWS CloudWatch

Results
  • Unified siloed order and stock data across 3 international retail brands.
  • Enabled automated KPI dashboards with near real-time refresh.
  • Reduced query latency for BI reports by 80% through schema redesign and indexing.

🟧 Reporting lag reduced from 2 hours to under 10 minutes.
🟧 Inventory reconciliation accuracy improved by 95%.
🟧 Full traceability from transaction to product line across all stores.
