Suppose that you have been asked to create an information system for a manufacturing plant that produces nuts and bolts of many

shapes, sizes, and functions. What questions would you ask, and how would the answers affect the database design

Answer:

Following are the solution to this question:

Explanation:

In essence, both issues (relevant) were addressed, that form the design of the system, and all of the information collected and during initial analysis along with all subsequent stages will, in turn, affect the design of the system. Being aware, that perhaps the data is obtained to establish the entities, attributes, or relations. In particular, partnerships, clearly outline, or cardinal-ties are shaped by company policies derived from the creator's information. Example problems and the probable effects on the layout may be:

It will create the file concurrently for all depts, or would like to build and execute the database simultaneously with one dept?  

How would the work be to design affect the development process? In other terms, determine the range of the system as well  

as its limits about the bottom-up, centralized, or decentralized.

Do you want, and would you like an integrated framework to develop a single module? (Inventory, production, shipping, billing, etc.)  

Would you like a product code, output change, and form of controlling the bolts and bolts and dept? Impact: design of the logical and physical server.  

Perhaps you'd like to monitor the sources of every lot a raw resources for the nuts and bolts manufacturing? Impact: design of the logical and physical server. Model E-R.  

Perhaps you'd like to monitor consumers receiving shipments of bolts and nuts? Impact: design of the logical and physical database. ER model.  

Its documents will you demand, or to whom can these documents be transmitted? What specific reporting requirements?  

Reactions to such concerns relate to the design, execution, testing, or subsequent functioning of the logical and physical system.

Describe the purpose of shell scripts. Provide one example to reflect the use of variables, constructs, or functions.
Sindrei [870]

Answer:

Kindly check explanation

Explanation:

Shell scripts are used for writing codes which may involve writing together a complete set of task in a single script. These set if codes or instructions could be run at once without having to run this program one after the other on a command line. This way it avoid having to repeat a particular task each time such task is required. As it already combines a sequence of command which would or should have been typed one after the other into a compiled single script which could be run at once.

A shell script could be written for a control flow construct :

if [expression]

then (command 1)

else (command 2)

Refer to the method f:
Goshia [24]
<h2>This function will land up in infinite function call</h2>

Explanation:

first time when the function gets invoked,

f(6,8), so k=6 & n=8, inside the function it checks k==n, ie. 6==8, returns false, then one more if is available, so 6>8 is check for , once again it is false and else loop is executed, the function is called recursively using f(k-n,n), that is f(6-8,8), it means f(-2,8) is passed.

Second time,

if(-2==8) is false, so if(-2>8) is again false and function f(-10, 8) is called

if(-10==8) is false, so if(-10>8) is again false and function f(-18,8) is called

if(-18==8) is false, so if(-18>8) is again false and function f(-26,8) is called

So this goes recursively and ends in an infinite function call.

A good administrative position to acquire as a stepping stone to further positions is
Andrew [12]

Answer:

A good administrative position to acquire as a stepping stone to future positions is an intern.

Explanation:

When an individual is an intern within an administrative sector, he will be able to learn many concepts and guidelines of this type of work, getting involved in various areas within the sector and accumulating knowledge that will serve him to occupy greater positions within the sector.

In this case, being a trainee is a better option due to the exchange of areas in which he can participate and which will show where his greatest capacities are concentrated within an administrative sector.
