Answer:

Data modeling occurs at three levels—physical, logical, and conceptual.

  • A physical model is a schema or framework for how data is physically stored in a database.

  • A conceptual model identifies the high-level, user view of data.

  • A logical data model sits between the physical and conceptual levels and allows for the logical representation of data to be separate from its physical storage.

Consider the formula: G=D+(A+C^2)*E/(D+B)^3 Show the order that a processor would follow to calculate G. To do so, break down th
motikmotik

Answer:

1. G=D+(A+C^2)*E/(D+B)^3

cobegin:

p1: (D+B)

p2: p1^3

p3: C^2

p4: A+ p3

p5: E/p2

p6: p4 * p5

p7: D + p6

   :G

coend

2. Now The value A=2, B=4, C=5, D=6, and E=8

p1: 6+4 =10

p2: p1 ^3= 10^3= 1000

p3: c^2= 5^2 =25

p4: A + p3= 2 +25 =27

p5: 8/1000

p6: 27 *8/1000

p7: D+ P6= 6+ 216/1000

      = 6216/1000

      =6.216

Explanation:

The above, first bracket with power is processed, and then power inside and outside bracket. And rest is according to BODMAS, and one process is solved at a time.
