Gap Analysis

Minor Gaps (Remember level, −2 points)

The Remember level is strong but could include two additional recall items to reach full marks:

  1. 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.

  2. 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

  1. (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.

  2. (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.

  3. (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

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
