Errorprocessing

Errorprocessing refers to the systematic practice of detecting, diagnosing, and managing errors that occur in software systems, networks, and processes. Its goal is to maintain reliability, data integrity, and user experience by controlling how faults are detected, handled, and recovered from across the system lifecycle.

Core components include error detection (monitoring, input validation, exception signaling), classification and prioritization (severity, impact, frequency), handling strategies (retry with backoff, fallback, circuit breakers, fail-fast, graceful degradation), and observability (structured logging, metrics, distributed tracing). Recovery and compensation cover idempotent operations, rollback procedures, and compensating actions to restore consistent state.

Techniques span programming language features (try/catch, monads), design patterns (error boundaries, sentinel values), and architectural patterns (bulkheads, retry policies, circuit breakers). Data-centric errorprocessing emphasizes schema validation, input sanitation, and audit trails. Operationally, it is integrated with incident response, post-incident reviews, and compliance with data integrity and privacy requirements.

Common metrics include error rate, time to detect and resolve, and user-visible impact. Challenges include distinguishing genuine faults from transient noise, preventing error cascades, and balancing rapid recovery with safety. Applications span client applications, servers, distributed systems, and embedded devices.
