Answer:
See explaination
Explanation:
An Academic Database deals with the information pertaining to the records of students of an institute. The various fields which can be associated with a student are Name, Unique Identification Number, Marks in various subjects, Grades, Courses Taken and so on. Most of the fields mentioned above have some or other form of validation that is required for the DB to be consistent and follow the basic properties of a database.
One field where range validation can be used is MARKS. In the marks field, the range of marks will be say 0 to 100 and anything below 0 or above 100 must be reported to the database administrator. Another field where we can apply a range validation is AGE in which the range of age allowed could greater than say 10, if it is a college and maximum age could be say 60. Thus, the range check on the AGE field is 10 to 60.
One field where choice validation can be used is GENDER. In the gender field, there could be multiple choices like Male, Female and Others. Thus, out of the available choices we have to select only the available choice and only one choice must be selected where we can apply choice validation. Another field is COURSE, where we can have a list of courses a student can opt for and out of the available courses can select one.
Thus, there are multiple fields where we can apply various types of validation and it is important to explore the area for which the DB has been created understanding all the scenarios and attributes of the problems that are associated with that area.
Answer:
Indexical Signs
Explanation:
According to Charles Peirce, when there is "existential" relationship that exist between the sign and interpretant, then indexical signs are involved. This implies that at some point in time, they have existed at the same time or in the same place. One indexical sign of a human being is Fingerprints. However, photographs are classified as indexical signs testifying that at some moment, the camera was present.
Answer:
True
Explanation:
for loop is used to repeat the process again and again until the condition not failed.
syntax:
for(initialize; condition; increment/decrement)
{
Statement
}
But we can omit the initialize or condition or increment/decrement as well
the syntax after omit the initialization,
for( ; condition; increment/decrement)
{
Statement
}
The above for loop is valid, it has no error.
Note: don't remove the semicolon.
You can omit the condition and increment/decrement.
and place the semicolon as it is. If you remove the semicolon, then the compiler show syntax error.
Answer:
The audience development technique that best describe the process Nicolal wants to implement is;
C Pull technology
Explanation:
Pull technology is a form of network mode of communication in which the initial data request comes from the client side of the network for it to be handled by the server side of the network.
Given that Nicola wants a demand-based content to his website for customers to access information when they wish to, the process is similar t the podcasting in which each new content is posted to a specific RSS feed from where it can be requested by a mobile app, directory or a RSS feed reader
The counter technology is a push technology where the servers push content to intended clients, such as for an incoming call, instant messaging, synchronous conferencing (online c h a t) and files.
Answer:
You should be strong, and be sure about what you want to say. Make sure when you speak it is clear, and makes sense.
Explanation:
If you don't speak up or sound like you know what you are talking about. I like to think of it as dancing. Act like you own the stage, or in your case, like you own the presentation. Also, I suggest you speak to your teacher in private, about him ignoring you. If I were you, I would look for newer friends. Ones that won't ignore you.
