Learning objectives

• Explain BASE: The Alternative Vocabulary and Where It Fits using the language of guarantees, anomalies, and implementation costs rather than vague “strong vs weak” intuition.
• Use BASE: The Alternative Vocabulary and Where It Fits to reason about what a database actually promises under concurrency and failure.
• Use database-internals, ddia to connect the learner-facing model to isolation, recovery, distributed coordination, and real failure modes.

Prerequisites

• Comfort with relational data modeling and the basic mechanics of storage engines and replication.

External enrichment

• PostgreSQL Documentation: Transaction Isolation (official_docs_companion) - Anchors anomaly and isolation discussions in a concrete implementation instead of abstract labels alone.
• CockroachDB: Transaction Layer Architecture (optional_deep_dive) - Useful when the learner wants to see how transactional guarantees change under a distributed SQL architecture.

AI companion modes

• Explain simply
• Socratic tutor
• Challenge my understanding
• Diagnose my confusion
• Connect forward / backward
