# Data Contracts ## Skill Profile *(Select at least one profile to enable specific modules)* - [ ] **DevOps** - [x] **Backend** - [ ] **Frontend** - [ ] **AI-RAG** - [ ] **Security Critical** ## Overview A Data Contract is a formal agreement between a data producer (e.g., a microservice) and a data consumer (e.g., a data platform) that defines the structure, semantics, and quality of data being shared. It acts as a "service-level agreement" (SLA) for data. **Core Principle**: "Data should be treated as a product, and products need specifications." ## Why This Matters - **Stability**: Contract ensures stable data interfaces - **Quality**: Schema validation prevents data quality issues - **Accountability**: Contract violations are tracked and addressed - **Efficiency**: Clear specifications reduce development time - **Security**: Contract terms protect sensitive data --- ## Core Concepts & Rules ### 1. Core Principles - Follow established patterns and conventions - Maintain consistency across codebase - Document decisions and trade-offs ### 2. Implementation Guidelines - Start with the simplest viable solution - Iterate based on feedback and requirements - Test thoroughly before deployment ## Inputs / Outputs / Contracts * **Inputs**: - Schema definitions - Data events and messages - Quality requirements - SLA definitions * **Entry Conditions**: - Schema is defined - Validation rules are established - Monitoring is configured * **Outputs**: - Validated
