This week's items

Due the week it opens — same standard as PGCC. Weekly gates are completed in class.

Know these cold

  1. Table → records (rows) → fields (columns). Primary key identifies the row; foreign key links tables.
  2. SQL: SELECT reads, INSERT adds, UPDATE changes, DELETE removes.
  3. Indexes make searches fast. A DBMS (MySQL, Access) manages databases.
  4. Relational (tables) vs non-relational (key-value, document).

Meerk's quiz — open the Lesson 5 gate

10 questions, no time limit. 85% on your first attempt in a 24-hour window opens the gate. Retakes inside the window are practice — they help you learn, they don't count. Work alone; the point is to know it, not to have seen it.
