Cxis

Cxis is a term used in information technology to denote a modular framework for cross-system data exchange and interoperability. In its broad sense, a Cxis architecture aims to enable secure, scalable sharing of information across organizational boundaries by decoupling data producers from consumers through standardized interfaces and data models.

There is no single canonical definition or formal standard called Cxis. The term appears in multiple research and industry discussions, and implementations vary in scope and terminology. As a result, 'Cxis' describes a family of approaches rather than a unique product or protocol.

Common elements in Cxis discussions include a data model layer that harmonizes schemas from participating systems, an interface layer that exposes APIs or messages, a security and governance module for authentication, authorization, and auditing, and adapters that connect legacy or heterogeneous data stores to the framework. Some proposals favor event-driven pipelines; others emphasize synchronous APIs or publish–subscribe patterns.

Applications cited for Cxis concepts include supply-chain visibility, electronic health information exchange, enterprise data sharing, and smart-city platforms. Practical deployments focus on data quality, governance, latency, and privacy controls, with success depending on alignment with policy and regulatory requirements.

Because Cxis lacks a universal standard, interoperability depends on negotiated conventions and reference architectures rather than a single protocol. Major challenges include ensuring data quality, managing cross-domain access, and avoiding performance bottlenecks in large-scale environments.
