Independent databases
Departmental schemas had little connection and could not be redesigned as part of the project.
Anonymous textile manufacturing case study
Connecting textile material flow across the supply chain
A growing textile provider needed to coordinate material, product, data, and messages across supply, manufacturing, warehousing, sales, and distribution without changing the schemas of its existing departmental databases.
The situation
The physical supply chain was connected, but its departmental systems were not.
Technical, sales, warehouse, compounding, and distribution teams each depended on information and materials passed from other groups. Their databases had developed independently, with limited connection between them.
The client wanted real-time tracking and coordinated instructions across the operation, but the existing database structures could not be changed and the platform also needed to accommodate a different database technology.
The product challenge
Create one operational flow across systems that had to remain structurally independent.
Integration had to respect existing database constraints while supporting complex, changing workflows across internal and external participants.
Complex cross-team workflow
Instructions, feedback, material, and product status moved in multiple directions across many participants.
Technology transition
The application needed flexibility to work with SQL Server and support a move to Oracle without rewriting the business layer.
The solution
A three-layer Java application used object-relational mapping to integrate data without rewriting existing schemas.
The team joined the work from analysis through design, implementation, and remote support, documenting architecture, classes, sequences, data flow, and components before building against the client’s database design.
- 01
Separate web and business behavior
Use Struts to route requests, validate data and business rules, and keep presentation concerns maintainable.
- 02
Unify access to independent data
Use Hibernate as the object-relational layer for separated databases without forcing schema changes.
- 03
Support operational outputs
Add connection pooling, logging, PDF support, shared libraries, and reusable table presentation around the core workflow.
How we worked
Document the integration boundary before implementing against constrained data sources.
Analysis translated the client’s functional specification into a full system design with architecture, class, sequence, data-flow, and component views.
The application was built around the database structures supplied by the client instead of changing schemas to make integration easier.
Open frameworks and isolated layers kept routing, validation, presentation, business behavior, object mapping, and database technology from becoming tightly coupled.
01Analyze
Map departments, handoffs, and data sources.
02Design
Document architecture and component behavior.
03Integrate
Connect independent schemas through Hibernate.
04Support
Add validation, logging, pooling, and operational outputs.
The result
The solution established a shared workflow and traceability layer across previously separate departmental systems.
The delivered architecture connected material and information flow across technical, sales, warehouse, compounding, and distribution work while preserving the existing database structures and supporting more than one database platform.
Cross-department flowfor data, instructions, material, and feedback
Schema-preserving integrationacross independent databases
Database flexibilityfor SQL Server and Oracle
Traceability across handoffs
The system was designed to follow raw materials and products as work moved among supply-chain participants.
Coordination in both directions
Departments could receive instructions, provide feedback, and make current information available to the next step.
A maintainable integration layer
Three application layers and object-relational mapping isolated business workflow from database-specific details.
