> The class 'Vectors' is the a base data structure that contains a number of 
> rows in the DSM (decomposition storage model) manner. In other words, Vectors 
> object should have a list of columns, each of which is an array of primitive 
> types, such as int, long, and double. Also, what each column values can be 
> nullable should be considered for its design.
> The cache effect also should be considered for determining the size of each 
> vector. According to the MonetDB/X100 paper, 1000 values for each vector are 
> the best size for cache effect.
