Data Management & Ownership Requirements
Purpose
To establish clear data ownership, enable autonomous operation, support data-driven decision making via Data Products, and prevent tight coupling through shared database dependencies.
Scope
Data ownership boundaries, cross-product data access patterns, data replication strategies, schema versioning, data product design, and data protection.
Requirements
| ID | Name | Description |
|---|---|---|
| REQ-DATA-1 | Data Ownership | Each product MUST have clearly defined ownership of the data it needs to fulfil its responsibilities, including authoritative sources and write boundaries. |
| REQ-DATA-2 | No Direct DB Access | Products MUST NOT depend on direct database access to other products’ data; all cross-product data MUST be accessed via contracts such as APIs, events, or data products. |
| REQ-DATA-3 | Autonomous Execution | Products MUST be able to perform core functions without synchronous access to external data sources, utilizing replication or eventual-consistency patterns. |
| REQ-DATA-4 | Data as a Product | Each product MUST expose its data via well-defined “data products” treated as APIs, with clear documentation and access control for operational and analytical use cases. |
| REQ-DATA-5 | Schema Versioning | Shared data formats and schemas MUST be versioned and evolved in a backward-compatible manner to ensure system consistency. |
| REQ-DATA-6 | Data Classification | Security requirements (confidential, internal, public) MUST be defined per data set and enforced across storage, transport, and exposure. |
