external schema - Answer-Also called a subschema, this is a specific view of the data utilized by an end user conceptual schema - Answer-This describes all the entities, attributes, and relationships together with integrity constraints. Each DB has exactly one. internal schema - Answer-A complete description of the internal model, down to the physical storage of data. Each DB has exactly one. logical data independence - Answer-The immunity of the external schemas to changes in the concept...

ENGR 102 Exam 2 Questions and Answers Graded A+ Can you multiple tuples? nope vector1 = (1, 2, 3) vector2 = (2, 3, 4) dotp = vector1 * vector2 print("The dot product is", dotp) ERROR: u can't multiple tuples together mystr = "Howdy" mylist = [2, 0, 2, 0] mytuple = (mystr, mylist) mylist[3] = 5 print(mytuple) ('Howdy', [2, 0, 2, 5]) if the list changes, then the tuple changes it doesn't work if it's a string def plus1_3(x): return (x + 1, x + 3) print(plus1_3(2)[0]) 3 Apparentl...

How is Python implemented? correct answersPython is interpreted, similar to Java it is compiled into byte code and then executed by the Python VM. What are the two modes supported by Python? correct answersNormal Mode: entire .py files are read and compiled Interactive Mode: read-eval-print loop (REPL) executes statements piecewise. How is Python typed? correct answersPython is strongly, dynamically typed language. It is strongly typed since we cannot perform integer operations on a strin...

A database model - -is a conceptual framework for database software The relational model - -is a database model based on mathematical principles, with three parts: 1. A data structure that prescribes how data is organized. 2. Operations that manipulate data structures. 3. Rules that govern valid relational data. A domain - -is a named set of possible database values, such as integers, dictionary words, or logical values TRUE and FALSE. A tuple - -is a finite sequence of values, each drawn...
