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.
Complete question :
Sue is planning a theme park trip for her husband, herself, and her three children. She has a budget of $500. Adult tickets cost $55 each, and child tickets cost $25 each. Which formula should go in cell B4?
Answer:
=E1B1+E2B2
Explanation:
Cost of adult ticket = $55
Child ticket = $25
Number of adult = 2
Number of children = 3
Assume :
Cost of adult ticket = $55 = E1
Child ticket = $25 = E2
Number of adult = 2 = B1
Number of children = 3 = B2
The formula that should go into cell B5 in other to calculate total amount :
Total should be :
($55*2) + ($25*3)
=E1B1+E2B2
