A relationship that is not valid A relationship that is implied but not directly defined A relationship between distinct instances of the same entity A relationship between a parent and child entities 2. An attribute that serves to uniquely identify a particular entity is called a(n) ________. 3. The individual pieces of information about each entity are called _________. 4. The structure and organization of a database is defined by its ___________

Step 1
This means that the relationship occurs between different entities of the same type. Step 2: An attribute that serves to uniquely identify a particular entity is called a primary key. The primary key is used to ensure that each entity in a database is uniquely Show more…

The following is a recursive definition of $a^{n}:$ $$\begin{aligned}a^{1} &=a \\a^{n+1} &=a^{n} \cdot a \end{aligned}$$ Prove, by induction, that$$a^{n+m}=a^{n} \cdot a^{m}$$ $$\left(a^{n}\right)^{m}=a^{n m}$$. (Don't try to be fancy: use either induction on $n$ or induction on $m,$ not both at once.)
Differentiate the recursion relation (5.8a) and use the recursion relation (5.8b) with $l$ replaced by $l-1$ to prove the recursion relation $(5.8 \mathrm{c})$.
