  • Data structure

    Data structure incorporated in LeoStatistic could be described as a array of tables. A term "data" is used here in a sense of a collection of numerical measurements (in most broad sense like an output of physical experiment, customers data, price - time series etc.) that could be organized in a form of a tables. One column of data also refers here as (field or variable) has several attributes:

  • name
  • status to be an Argument, a Value or Inactive;
  • marker's color, shape and size for values.

    Data structure is organized as a collection of tables with the same number of columns (parameters) these (tables) could have different number of records.  All of these tables must to have exact the same ordered assignment of parameters by their status.

    There is a principal example of data structure organization in LeoStatistic as it could be seen outside:

    
    Series 1			
    Name:	x	y	z
    Status:	A	V	I
    Shape:	N/A	square	N/A
    Color:	N/A	blue	N/A
    Size:	N/A	3	N/A
    1	0	4	11
    2	0.25	4.0	11.5
    3	0.5	4.25	13.0
    4	0.75	4.5	15.8
    5	1	5	20
    6	1.25	5.5	25.9
    7	1.5	6.2	34.0
    8	1.75	7.0	44.8
    9	2	8	59
    10	2.25	9.0	77.1
    11	2.5	10.2	100.0
    12	2.75	11.5	128.6
    13	3	13	164
    14	3.25	14.5	207.0

    16	3.75	18.0	321.2
    17	4	20	395
    18	4.25	22.0	481.7
    19	4.5	24.2	583.0
    20	4.75	26.5	700.5
    
    Series 2			
    Name:	x	v	z1
    Status:	A	V	I
    Shape:	N/A	circle	N/A
    Color:	N/A	green	N/A
    Size:	N/A	9	N/A
    1	0.01	-5	22.5
    2	0.33	-4.9	19.6
    3	0.66	-4.7	17.2
    4	0.99	-4.0	11.2
    5	1.32	-2.7	2.2
    6	1.65	-0.5	-4.7
    7	1.98	2.7	2.6
    8	2.31	7.3	48.6
    9	2.64	13.3	174.5
    
    

    The screenshot of LeoStatistic corresponding to the above set of data is presented here:

    The largest number of records in one series that LeoStatistic can handle programmable is 232= 1010 cells (number rows*number columns for all data series). But, of course, realistically speaking much smaller data sets can be calculated without lost of patience with the help of modern computers. But as soon it's subjective - try for yourself.

    An internal presentation of the data structure in LeoStatistic is of course differ - all data a in one array. LeoStatistic is using a NetCDF format for storage or data as properly one. Our LeoNetCDF application could be used for observing and in some extend modification of data and data setting although we don't recommend it.
