comment Topics for master's project using Mathematica
Hello and welcome to Mathematica SE! I'm sorry that I had to close your first question, but this is a very broad and vague question, the kind that this site is ill equipped to answer. You might be better off asking your supervisor/advisor this question. After all, what they're there for :) If he/she doesn't have any good suggestions, you might try asking at community.wolfram.com

comment Performing analysis of data extracted from an SQL database
If out is your expression w/o TableForm, then Evaluate[Symbol /@ First@out] = Transpose@Rest@out should work. This doesn't have anything to do with SQL queries though...

comment Is Daylight Savings Time accounted for when using AbsoluteTime[]?
This is the first thing mentioned in the documentation — "AbsoluteTime[] uses whatever date and time have been set on your computer system. It performs no corrections for time zones, daylight saving time, etc. "

comment Diagonal minors of matrix
"Since I am going to calculate the minors of big matrices and I only need to know the diagonal elements, is there a way just to calculate the diagonal elements in minor matrix?" — Surely, performance is an issue here.

comment Convex optimization
@DanielLichtblau The remark included the clause following it — "and enforce sparsity". NMinimize handles $\ell_1$ minimization fine. In compressive sensing/sparse theory, one wishes to solve an $\ell_0$ minimization problem, but because that is NP-hard, you do $\ell_p,\ 0<p\le 1$ minimization under certain assumptions/conditions and with other possibly non-linear constraints. I guess my phrasing wasn't the best way to put it but nothing better comes to mind now... will update it if I think of something better.

comment Why Mathematica chooses bracket for function arguments over parenthesis?
"If function arguments are denotes as f(x), then array[i] could be used as array index.(c.f. Mathematica uses [[i]] here.)" — is (f + g)(x + y) parenthesizing and multiplying two terms or is it a function call (like (f + g)[x + y] in the current syntax)?
