Database Administration Questions

The Mirror can turn everything around without moving.

A candidate key is a column, or set of columns, in a table that can uniquely identify any database record without referring to any other data. Each table may have one or more candidate keys, but one candidate key is unique, and it is called the primary key.

Foreign keys are the columns of a table that points to the primary key of another table. They act as a cross-reference between tables.

In detail : A Foreign key is a field (or collection of fields) in one table that uniquely identifies a row of another table or the same table. In simpler words, the foreign key is defined in a second table, but it refers to the primary key or a unique key in the first table.

A seemingly simple question that is often difficult to answer, it can result in a great interview going disastrously wrong.

Here "What interests you about the position offered?" is a problematic question for anyone, even the most prepared interview candidate. It is one of those questions that might decide between selected individuals who have the same qualifications and experience.

When asked "what about this job interests you", the interviewer wants to know why you decided to apply specifically for this job and why do you consider this position fitting you and your career plans.

The best bet is to take the most important element of the said job and talk about it.

For example if the job requires effective team work capabilities, you may construct your answer in this way:

Question: What is the 'thing' that interests you about this job?

Answer: One of the things that are of my best interests in this job is the opportunity to work in a team environment. I always wanted to work with hard-working, professional, experienced people. I love contributing the team effort, bringing out the best in myself and in my teammates for fulfilling our work goals and reaching top results.

I trust that I can perform great by applying sound principles of teamwork as I did in my previous jobs. I seek timely and consistent feedback designed to improve not only my performance as well but the team’s performance as well. I consult with people, try my best and treat everyone positively/equally.
