Creating a Cube via a Process ​

All of the following functions are documented in full in the Process Documentation section of the portal.

Cube Management Functions ​

These functions can be used to manage cubes, not the information stored within them.

js
cube.create(cubeName, dim1 - dimN);
cube.exists(cubeName);
cube.remove(cubeName);

Cube Data Functions ​

These functions are used to store, retrieve or affect the data values in a cube.

cube.wipe is commonly used at the beginning of a process to clear out the portion of the cube which is about to be loaded.

js
cube.get(cubeName, elm1 - elmN);
cube.set(value, cubeName, elm1 - elmN);
cube.increment(value, cubeName, elm1 - elmN);
cube.wipe(cubeName, elm1 - elmN);

Optimisation Functions ​

These functions can be used to improve the performance of loading data into a data cube. These are not used in most models.

js
/*
turn off/on the write-after log. 
This log is typically on by default and is used to recover information 
    should the environment crash for any reason.
*/
cube.log(cubeName, bShouldLog);
/*
turn off/on the formulas of a cube. 
This can be used to speed up loading into a cube 
    which feeds a multitude of calculated cells.
*/
cube.formulaEvaluation(cubeName, bShouldEvaluate);

Cube Slice Functions ​

When a process needs to iterate over a large slice of information from a cube the cube.slice function can be used to generate a iterator object which can progress through the cells of a cube slice.

js
//create a slice of the Sales cube containing the 'Units Sold' in '2017' and '2018'. 
//This slice excludes any plan data by restricting on 'Actual'
var slice = cube.slice("Sales","2017|2018","","Actual","","","Units sold"); 
while( !slice.EOF() ) {
    var elms = slice.Next();
    /*
    `elms` will be returned as an array 
    i.e. 
    [
        "2017 - Jan","Product A","Actual",
        "Department A","Retail Sales",
        "Units Sold", 5293
    ]
    The last value in the array is the value stored at the 
    intersection described by the proceeding array items.
    */

}

Standard Template for loading data into a Cube ​

For information on how scripted processes are structured and how each of the standard functions is used, refer to the Scripted Processes documentation.

js
/**
 * Author: example name
 * Date Created: 2022-12-15
 * Date Modified: 2022-12-15
 * Date Deprecated: #N/A
 *
 * Parent Process: #N/A
 * Primary Function: Populate the Sales cube
 * Target: Sales
 * Datasource: CSV file from business users
 * Datasource Fields: 
 *      dept - department code
 *      product - product code
 *      channel - sales channel code
 *      month - the month in YYYY - MMM
 *      units - units sold
 *      revenue - invoiced revenue
 * 
 * Wipes and then reloads the Sales cube from a 
 *  CSV file containing all history
 */
var cubeName = "Sales";

function pre() { 
    //do nothing 
}
function begin() {

    /*
    wipe the Actuals data from the cube against the 
        Units and Revenue Measures.
    */
    cube.wipe(cubeName, ["","Actual","","","","Units|Revenue"]);

}
function data(record) {
    /* 
    Increment the Units and Revenue measures in the cube 
        (at the intersection of Month, Actuals, Department, Product and Channel).
    */
    cube.increment(record.units, cubeName, record.month, "Actual", record.dept, record.product, record.channel, "Units");
    cube.increment(record.revenue, cubeName, record.month, "Actual", record.dept, record.product, record.channel, "Revenue");

}
function end() {
    //do nothing 
}
