The order of the rows and columns is important to the DBMS. True or False - correct answer False PRODUCT yields all possible pairs of rows from two tables, also known as the _______ product. - correct answer Cartesian According to Codd's ______ rule of relation database, "Application programs and ad hoc facilities are logically unaffected when changes are made to the table structures that preserve the original table values (changing order of columns or inserting columns)." A. com...

MACM 101 Midterm 2 Questions with 100% Correct Answers Lecture 14: Relations - The connection between things or people Cartesian Product - The Cartesian product of sets A and B, denoted by A × B, is the set of all *ordered pairs* of elements from A and B A × B = { (a,b) | a ∈ A, b ∈ B } These are two dimensional Ordered pair - The elements of the Cartesian product are ordered pairs. In particular, (a,b) = (c,d) if and only if a = c and b = d Its a pair of numbers that can be used ...

Associative Entity An associative entity is an element of the entity-relationship model. All relationships for the associative entity should be many. Attribute An attribute is a property or characteristic of an entity. Binary relationship A binary relationship is a relationship between two entity types. Candidate Key Is any column or a combination of columns that can qualify as unique key in database. Cardinality Cardinality represents the maximum number of entities that can be involved in...

1. We can choose δx = 0, δy = δ. The equation of the ellipse x = cosθ cosωt y = sinθ cos(ωt − δ) reads in Cartesian coordinates The direction of the axes is obtained by looking for the eigenvectors of the matrix which make angles α and α + π/2 with the x-axis, where α is given by tanα = cosδ tan2θ The vector product of the position ~r with the velocity ~v, ~r ×~v, is easily seen to be so that the sense of rotation is given by the sign of the product sin2θsinδ...
