Answer:
relation of FDs are {a, b, d, h}. From these all but {h}
seem plausibly part of keys. Calculating the closures of likely candidates gives:
{a, b} + = {a b, c, i}
{b, d} + = {b, d, e, f}
{a, d} + = {a, d, g, h, i, j}
{a, b, d} + = {a, b, c, d, e, f, g, h, i, j}
decompose r into 2nf and then 3nf relations shown in attachment.
Step- by-Step Explanation
Explanation is given in the attachment.
Answer:
312 employees participated in the training
Step-by-step explanation:
Given;
employee to instructor ratio is 24 to 2
there are 26 instructors for the training
let the total number of instructors be I = 26
let the total number of employees be e = ?
employee to instructor ratio is 24 to 2, e : I = 24 : 2
e : I = 24 : 2 = e : 26
Therefore, the total number of employees who participated in the training is 312
