Answer: getfenv() is a type of function. Particually a envirotment function. for a lua coding.

Explanation: What this does it goes thourgh line of code in a particular order.

This means. getfenv is used to get the current environment of a function. It returns a table of all the things that function has access to. You can also set the environment of a function to another environment.

Forgot to include examples of where this could be used. Although not very common uses, there are some. In the past Script Builders used getfenv to get the environment of a script, and setfenv to set the environment of a created script’s environment to a fake environment, so they couldn’t affect the real one. They could also inject custom global functions.

Not entirely sure if this uses getfenv or setfenv, but the use in Crazyman32’s AeroGameFramework is making the environment of each module have access to other modules without having to require them, and having access to remotes without having to directly reference them.

How to represent derived attributes in database?

Vlad1618 [11]

Answer:

Derived attribute can be defined as a type of attribute where its value will be derived from one or more of the other attributes of the same entity set.

Explanation:

An example of derived attribute is when we have an entity set called General. The set then has attributes like [Form], [Characteristics], [Address}, (Employment No).

(Employment No) which is represented distinctly in the attribute set can be called a derived attribute if it can be derived from one or more of the other attributes.

Derived attribute can be gotten through calculating values and not storing values.

For example, let us consider the following record of Teachers records;

(‘Teacher Number’, ‘Name’, ’Date of Birth’, Age today)

(‘E105’, ‘Samson’, ’07-Dec-1990’, 0)

This record shows that the teacher Samson was born on 7th of December, 1990. At the time of record insertion, he was born and 0 years old. What will be the value of his age on ’07-Dec-2000’? It is about 10 years. It clearly shows that the value is not fixed and it is a variable whenever the DOB is adjusted.

Therefore, we are not creating our table with derived attributes in it. Instead, the values ofderived attributes can be calculated at the time of retrieval and shown to the user. Hence, the record will look like as follows;

(‘E105’, ‘Samson’, ’07-Dec-1990’)

This means that 0 is a derived attribute from the Date of birth.
