What are the advantages of performing a database normalization?
There are many advantages of performing a database normalization. Some of the advantages include faster index searching, data commands are faster with less indexes and a more compact database with less null data.
How do you convert ordered data to nominal data?
I think you mean ordinal data. Similar to the golf tournament, you need to determine where to "cut" (from the ordinal data) so as to divide the data into different categories (to the nominal data). For example, if the ordinal data range from 1 to 6 (where 1 = the best) and the cut is 3, then you convert all the numbers from 1 to 3 to "1" (which represents "good") and the all numbers from 4 to 6 to "2" (which represents "bad"). In other words, 1, 2, and 3 from the original ordinal data set are converted to "1" (ordinal data); whereas 4, 5, and 6 from the original date set now become "2" (ordinal data). Eddie T.C. Lam
How do you find the quartiles of a data set?
First arrange the data set in ascending order. Suppose the data set consists of n observations. the index for the lower quartile is (n + 1)/4 and the index for the upper quartile is 3*(n + 1)/4. Find the values that correspond to the number in these positions in the ordered list. For example, if n = 15, then lower index = 4 and upper index = 12. So the lower quartile is the fourth number and the upper quartile is the twelfth. If n is large, you may skip the +1 and just look at n/4 and 3n/4. Often the indices are not integers. Then, if you are a beginner (nd the fact that you asked this question suggests that you are), find the nearest whole numbers for the two indices. Otherwise you need to interpolate and that is a whole new ball game!

What is index in sql?
Index is a data structure that improve the performance of data.
What types of index data structures can you have?
There are three types of index data structures: unique, non-unique, bitmap
What might be caused by a clustered index?
A clustered index in a database can improve the retrieval speed of data, as it physically orders the rows of a table based on the indexed column or columns. It can also help reduce the amount of data pages that need to be read when querying data. However, because the data is physically ordered based on the clustered index column, updates to this column can be expensive.
What is clustered index in database?
The data is stored along side the index keys, so when a query searches by the index, once it's found the "leaf" in the index tree, it usually has gotten the data in the same disk read. So your searches by that key are much faster. The down-side is that it takes much longer to save data with a clustered index, because it has to make space where the key should be stored for the table data.
What type of index do you use to leave the order of the data rows unaffected?
non cluster index
What type of data is acceptable for arrays index?
The details depend on the language, but the index of an array is usually an integer data type. Anything that is compatible with an integer can be used.

How do you work out speed using mean and median?
Mean is the average of a set of data points = (Sum of all data) / Quantity of DataMedian is the middle of a set of data points = Data whose index is the integer nearest ((Number of Data+1) / 2)Example Data:2, 3, 5, 3, 2The mean = (2+3+5+3+2)/5 = 15/5 = 3The median = Index((5+1)/2) = Index(6/2) = Index(3). The third item on our list is 5.
How the index of the DBMS is organized and works?
A database index is a data structure that improves the speed of data retrieval operations in DBMS. An index can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records. Most indexes use a B-tree structure. A B-tree is a tree data structure that keeps data sorted and allows searches, sequential access, insertions, and deletions in logarithmic amortized time. The B-tree is a generalization of a binary search tree. The B-tree is optimized for systems that read and write large blocks of data. There are several index types out there: Bitmap index Dense index Sparse index Reverse index Etc...
