How vinay6697/product-management-system-spring-jdbc works
This is a console-based product and inventory manager. The user selects CRUD, category-search, low-stock, or stock-adjustment actions; Main gathers input and delegates to the service, which validates requests before the DAO performs JDBC operations against PostgreSQL. Product is the shared domain record, and Spring configuration supplies the JDBC infrastructure. The README documents the product capabilities and layered design; the source excerpts show the console, service, DAO, model, and wiring. The database connection is documented, but no PostgreSQL runtime implementation is included in the excerpts.
