Store Rows in Array Algorithm: This subsidiary algorithm is used to store the
retrieved data from a CTT or a VET in a two-dimensional array. The number of array
rows corresponds a number of retrieved rows, and the number of array columns cor-
responds a number of retrieved columns. The column names are stored in the rst

element of the two-dimensional array, and the columns values are stored in the rest of

the array elements. The details of this algorithm are outlined in Algorithm 3.

Denition 3 (Store Rows in Array Algorithm). SRA rowsList denotes a set of retrieved
rows from a CTT or a VET where each of these rows is denoted by SRA row . Each
SRA row is a set of columns and each column is denoted by SRA col . SRA rown ( SRA colm )
denotes a value stored in the SRA colm of the SRA rown . SRA rowsListSize denotes the size
of the SRA rowsList . SRA rowSize denotes the size of the SRA row . SRA colNames denotes a set of
column names of a CTT or a VET. SRA colNamesSize denotes the size of the SRA colNames .
SRA array denotes a two dimensional array to store the retrieved rows.
