Answer:
2. A data modelling project using a packaged data model REQUIRES A GREATER SKILL than a project not using a packaged data model.
Explanation:
1a. Review of universal models:
A data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real world entities. It has become the standard approach used towards designing databases.
A universal data model is a template data model that can be reused as a starting point or a building block to jump-start development of a data modelling project, industry specific model, logical data models.
1b. Discuss how these are being used more widely today.
*Universal data models helps professional reduce development time, improve consistency and standardization while achieving high quality models.
*Higher quality: just as architects consider blue prints before constructing a building, one should also consider data before building an app. A data model helps define the problem, enabling one to consider different approaches and choose best ones.
*By properly modelling and organization's data, the database designer can eliminate data redundancies (needless repetitions) which are a key source for inaccurate information and ineffective systems.
2. Greater and advanced skills are adequate and required when data modelling project is done using packaged data model while fewer skills are required when data modelling is done without packaged data model.
Answer:
Option A. is correct
Explanation:
It now not possible for a country to be "occupied" by an invisible invader that arrives through airwaves and wireless networks. It is almost impossible to block foreign countries’ satellite broadcasts and Internet transmissions inspite of Spy satellites and other communications technology and Global positioning systems.
Option A. is correct
Answer:
The statement would be true
.
Explanation:
let, L = is a NFL player
M = teaches in CSU
N = has tattoos
Given that:
nfl player who teaches in csu = L^ M (this is false every time)
Above statement is L ^ M -> N
this would be true because
false -> true (true
)
false -> false (true
)
Second exp:
There are no players who teach in Csu therefore if we say they all have tattoos statement would be true.
Answer: A. System window and C. System Information window
Explanation:
Hi, RAM stands for Random Access Memory. RAM stores information about running programs in your computer, as long the computer is on.
To know how much RAM is installed on a system you can use the system window tool.
In windows 10 Right click on "Start Menu" and click on "System" in pop-up menu to open "System" window.
System window will show basic information of the computer, including the amount of RAM installed.
Also you can Type "System Information" in the search box, and select "System Information" from search results.
"System Information" window shows a more detailed system summary, of hardware resources and devices. Incluiding RAM.
Feel free to ask for more if needed or if you did not understand something.
