To implement a small database, a database designer must know the "1" and the "M" sides of each relationship and whether the rela

1 answer:
Marysya12 [62]3 years ago

Answer:

True.

Explanation:

"1" to "M" or 1 to many is a type of relationship between tables in a relational database. It means that against 1 record in a table, there can be 0 to many rows in the other table. Not that the many or child table doesn't need to have any record against the 1 or parent row, so the many side is optional.

Example can be a Customer and Order relationship. Where Customer is the parent table and Order is the child table. "A customer can have 0 to many orders".

1. How are computers helpful
d1i1m1o1n [39]

Answer:

Brainliest

Explanation:

It’s hard to imagine banks without technology. In fact, computers have been in use in banking since the 1950s, when Bank of America introduced a computer designed specifically for processing checks. Each new decade has brought innovations that change the way banks manage daily operations and serve customers. Today, you may not even leave your house to do your banking. As much as technology has changed the use of the computer in the banking sector, banks continue to adjust the way they do things.

A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,
Elan Coil [88]

Answer:

<u>720</u> possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10   (0-9 means total 10 digits)

r= 3     (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

        =10!/7!

        = 10x9x8x7!/7!

        = 10x9x8

        = 720
