Answer:
<em>DBMS Performance
</em>
Explanation:
Database tuning <em>defines a range of activities that are used to maximize and homogenize a database's output.</em>
This typically coincides with query tuning, but applies to database file layout, DBMS software selection, and database environment setup (operating system, CPU).
Database tuning helps to optimize the use of machine resources in order to carry out work as efficiently and quickly as possible.
Many systems are built to handle their use of system resources, but there is still plenty of space for enhancing their performance by tailoring their server and DBMS settings and configuration.
Answer:
It's a compact way of doing an if-else statement.
General Format is
<<em>condition</em>> ? <if condition is true> : <else>;
Example:
I could rewrite:
if(a==1) temp = 1;
else temp = 999;
as
temp = (a==1) ? 1 : 999;
I'd go with yes, but are you doing something malicious or just being nosey?
