Who can join coding classes across Ash Sharqiyah North?
Modern Age Coders teaches learners aged 6 to 67, including beginners, school students, university learners and working adults across Ash Sharqiyah North. Placement depends on observed ability, pace and objective rather than wilayat or age alone. The free first class uses an ability-matched task to identify a suitable course and format.
What is the Ash Sharqiyah North duplicate-join project?
The learner joins a synthetic activity table to a wilayat reference table. One reference key for Wadi Bani Khalid appears twice, so its activity row is duplicated and the regional total rises from 70 to 85. The repair enforces key uniqueness, tests row counts before and after the join, and reconciles the total to the source table.
Why does one duplicate key inflate every downstream figure?
A one-to-many join copies the matching fact row once for every dimension match. Any later sum, average denominator, chart or export now includes extra rows. The SQL can run without an error because the database does not know the analyst expected one reference row per wilayat.
How does the learner make the join safe?
The learner defines a stable wilayat identifier, requires a unique constraint in the reference table, rejects duplicate and missing keys, profiles join cardinality, compares row counts, reconciles pre-join and post-join totals, and stores source version. Deduplicating after aggregation is not accepted because it may hide which record was authoritative.
Are the project activities official regional data?
No. Every activity count, identifier and join result in the classroom tables is synthetic. Official sources are cited only for public administrative, geographic, tourism, heritage and development facts. The exercise does not measure actual learners, facilities, visitors or projects in Al Mudhaibi, Bidiyah, Wadi Bani Khalid, Dima Wa At Taiyin or another wilayat.
