Pearson Education (2006) 12. int/en/ SOHAC: Efficient Storage of Tick Data That Supports Search and Analysis Gabor I. hu Abstract. Storage of tick data is a challenging problem because two criteria have to be fulfilled simultaneously: the storage structure should allow fast execution of queries and the data should not occupy too much space on the hard disk or in the main memory.

Except the entries of the index column, all the entries of the binary change indicator matrix I are either 0 or 1 depending on whether or not the value of a cell in the tick data matrix M is equal to the value of the cell in the same column and the previous row of M : ⎧ ⎨ M (i, j) if the j-th column is the index column in M 0 if i > 1 and M (i, j) = M (i − 1, j) I(i, j) = ⎩ 1 otherwise where M (i, j) and I(i, j) denote the entries in the i-th row and j-th column of the tick data matrix M and binary change indicator matrix I respectively.

1). We use the term regular column for all the columns other than the index column. , for each regular column cj of M : cj ∈ P1 ∨ cj ∈ P2 ∨ ... ∨ cj ∈ Pk and for all i, j with i = j Pi ∩ Pj = ∅. , in this formulation, the index column does not belong to any partition. Then, for each partition Pi , a matrix Mi is derived from M by selecting the index column and SOHAC: Efficient Storage of Tick Data 43 those columns of M that belong to partition Pi . Subsequent rows of a derived matrix Mi may contain the same values in all the regular columns.
