Hello knowage users..i want to test knowage as open source tool and using it in my research . after installing knowage communtiy 7.4,  I plan for :

1- importing csv file with 32 columns and more than 10000 rows as my data input

2- presence this dataset in the integert mariadb 10.2 because i want to make sql querys to analyse the data using subquerys and analytical functions

 3- creating metrics and charts with allowed funktionalities dashboard.

so i hope to get answers to the following quetsion's:

1- wich is the best approach to creat hierarcheal from my input data in order to apply drill finctionality (if possible in community version of knowage) inside the dashboard?

2- is it better to seperate this data inside knowage into different tables and creating schema and Association inside it? and how to make this?

3-  As i know common table expression (cte) querys are not existed inside this mariadb version, how to handle this problem?

i thank u all for your answer.

Hello patto,

1) the drill in chart is supported by Knowage EE, in case you have a CE you can investigate if chart.js does support them

2) That depends on your data, usually it is better, but depends much on your DWH management....

3) The current mariaDB version in the CE installer should be mariadb-10.3.30-winx64, so WITH should be already available https://mariadb.com/kb/en/with/. Do you have any issue related?
