1.1.1. What Shape Is Your Data?
💡 First Principle: Data shape determines storage options. You cannot force mismatched shapes—a square peg won't fit a round hole. Asking "what shape?" before "which service?" eliminates 70% of wrong answers immediately.
| Shape | Characteristics | Storage Options |
|---|---|---|
| Structured | Fixed schema, rows/columns, relationships | SQL databases (Azure SQL, PostgreSQL) |
| Semi-structured | Flexible schema, self-describing (JSON/XML) | Document stores (Cosmos DB), Blob Storage |
| Unstructured | No schema, binary (images, video, audio) | Object storage (Blob, Data Lake) |
Reasoning Tool: When a question describes data, immediately classify its shape. If it mentions "tables," "columns," or "relationships"—structured. If it mentions "JSON," "varying fields," or "documents"—semi-structured. If it mentions "images," "video," or "binary files"—unstructured.
