Minimum self-check targets
You should be able to reconstruct these controlling ideas after the attempt:
- goals = availability, integrity, transaction performance;
- two families = Database Technology Support / Database Operations Support;
- DB vocabulary = stored collection / running DBMS / object grouping / distributed computer;
- roles = production reliability / application DBs / procedural logic / development-design / storage arrays;
- architectures = one place / multiple nodes / autonomy vs central control / loose vs integrated federated schema;
- cloud = owner-run VM / DaaS / managed hosting;
- ACID, BASE, CAP expanded exactly;
- environments = Build → Prove → Run, Sandbox beside the path;
- row vs column = OLTP-like whole rows vs OLAP-like selected-column scans;
- valid vs transaction time = real-world truth vs database-recorded truth.
