Gap Analysis
Minor Gaps (Remember level, −2 points)
The Remember level is strong but could include two additional recall items to reach full marks:
-
Common database products by type — students should be able to name canonical examples (PostgreSQL, MySQL → relational; Snowflake, BigQuery → analytical; Redis, DynamoDB → key-value; Cassandra, HBase → column-family; Neo4j, Amazon Neptune → graph; MongoDB, Couchbase → document). This anchors abstract paradigm knowledge to real-world systems they will encounter.
-
ATAM roles and artifacts — recall of the standard ATAM participant roles (evaluation team, project decision makers, architecture stakeholders, peer reviewers) and output artifacts (utility tree, risk list, sensitivity/tradeoff points, prioritized scenarios) supports precise use of the method.
Improvement Suggestions
-
(High impact) Add a "Representative Systems" subsection under each database type in the main topics list. Even a parenthetical "(e.g., PostgreSQL, CockroachDB)" helps learning graph generation map concepts to real systems and produces richer concept nodes.
-
(Medium impact) Add one or two Remember-level outcomes for canonical database product names by type and for ATAM artifact names to close the 6-point gap and reach 100/100.
-
(Low impact) Consider explicitly listing the PACELC model alongside CAP theorem in the main topics — it is referenced in Apply outcomes but not in the topics list. This is a minor alignment issue that may cause a learning graph generator to undercount the importance of this concept.
Concept Generation Readiness
| Dimension | Assessment |
|---|---|
| Topic breadth | Excellent — 6 database paradigms × multiple quality attributes + ATAM methodology + distributed systems foundations |
| Topic depth | Excellent — each topic implies 5–15 distinct concepts (storage models, consistency models, protocols, patterns) |
| Bloom's Taxonomy diversity | Excellent — all six levels covered; creates concept nodes across declarative, procedural, and strategic knowledge types |
| Estimated concept yield | 200–260 concepts — within the target range for a 200-concept learning graph |
| Readiness verdict | Ready to generate learning graph |
Estimated Concept Cluster Sizes
| Domain | Estimated Concepts |
|---|---|
| ATAM methodology and process | 20–25 |
| Relational databases | 20–25 |
| Analytical databases | 15–18 |
| Key-value stores | 12–15 |
| Column-family databases | 12–15 |
| Graph databases | 12–15 |
| Document databases | 12–15 |
| CAP / PACELC / consistency models | 18–22 |
| ACID and distributed transactions | 18–22 |
| Scale-out and sharding | 15–18 |
| High availability and five-nines | 18–22 |
| Workload characterization and selection frameworks | 12–15 |
| Total | 184–227 |
Next Steps
The course description scores 94/100 and is ready for learning graph generation.
Recommended immediate next step: run the learning-graph-generator skill to produce 200 concepts with dependencies, taxonomy categorization, and a quality validation report.
Optional before proceeding: - Add canonical product names to the Remember level outcomes (quick edit, +4–6 points) - Add PACELC to the main topics list for alignment with Apply outcomes
