About This Architecture

Multi-tier XML record retrieval and editor architecture with presentation, application, and data layers handling HTTP requests through WAF and load balancing. The application tier parses XML via PHP, builds DOM objects, applies XSD schema validation and XSLT transformations to generate HTML forms for client editing. Data tier integrates local and external SRU protocol databases, XML record stores, and schema/stylesheet repositories to support federated XML document management. This architecture demonstrates enterprise patterns for secure, scalable XML processing with schema-driven validation and presentation layer abstraction. Fork this diagram on Diagrams.so to customize database endpoints, add caching layers, or extend the SRU protocol handlers for your metadata systems. The separation of XSD schema loading, XSLT transformation, and form generation enables reusable component design across multiple XML document types.

How do you design a scalable architecture for retrieving, validating, and editing XML records from federated databases?

This diagram shows a three-tier architecture where the presentation tier handles HTTP requests through WAF and load balancing, the application tier parses XML, validates against XSD schemas, applies XSLT transformations, and generates HTML forms, while the data tier manages local and external SRU protocol databases plus XML record and schema repositories. The separation of concerns enables reusabl
