What are the basic principles of computer science?

I disagree with this. Studying computational efficiency is only one part of computer science.
What about the study of code generation and parsers? What about state machines? Or formalisms like relational algebra, algebraic type theory, distributed protocols, or lambda calculus? None of these things are "about" efficiency.

I (mis)understand that the question is about unifying principles of computer science
by studying the subject one is supposed to learn how to think about layered computer systems; However upon closer study each layer turns out to be of very different nature; what has the network in common with the sql database?
Well, there here are several basic fields such as algorithms / data structures / some understanding of complexity, without them one can't really understand much of anything. So these are the bricks and mortar used in the field.

This is too abstract of a question. Universities/colleges/schools have courses dedicated to the topic. Assuming that is what you are asking, check this course: https://www.coursera.org/course/cs101
Wikipedia. Google.
Principles
recursion & abstraction
logic, math and linguistics.
From here the field has a bunch of different areas that investigate aspects of this including things such as how difficult a problem is to solve, what kind of hardware is required to be able to compute a solution, the efficiency of an algorithm to solve the problem, data structures which make solving the problem more efficient, etc.
But ultimately the field is the study of efficiently in computing a solution to problems.
