Developed the foundational database architecture for the Patthethicc/Biotech_Lab_System repository, focusing on a comprehensive SQL schema to support lab resource management. The work centered on designing normalized tables for inventory, transactions, purchase orders, item details, and sales orders, with careful attention to relational modeling and data integrity through the use of constraints and relationships. By implementing this schema in SQL, the developer established a scalable structure for procurement, inventory control, and sales workflows. The approach demonstrated proficiency in database design and version control, laying the groundwork for reliable analytics and reporting across core operational entities within the system.
