Can we compare saiku with Pentaho Analyzer?

不想你离开。 提交于 2019-12-02 21:07:21
I'm currently in an internship and i have to create a whole BI application. I think i'll use pentaho, and I have to use just open source component. I know that Pentaho Analyzer is not free My question is: Is saiku an equivalent of analyzer? If yes, can I use it with pentaho instead of analyzer? thks Yes of course. Both the tools use the same underlying OLAP engine - Mondrian. Saiku is essentially the same as analyzer providing many of the same features - however it has a different architecture which additionally makes it very embeddable and pluggable. Plus Saiku can be used standalone too if

左心房为你撑大大i 提交于 2019-12-02 10:25:12
I have a data table component and seven multiple selectors related to it. And i want to reset all selectors to default value with a reset button.

Pentaho JNDI source name as parameter (Multi-Tennant)

戏子无情 提交于 2019-12-02 09:46:07
I have googled this for the last half an hour, and found hits for pentaho parameters etc but nothing that appears to ask or answer this question. I have a set of reports that are the same for each customer, but need to connect to different databases depending upon the customer who is running the report. So my idea is to pass the JNDI data source name to the report at runtime as a parameter, so that the customer will connect to the correct database. Is this possible, or is there a better way of managing a common set of reports that are used by different customers running on different databases

How to add a select all option to select component in CDE

谁都会走 提交于 2019-12-02 05:37:49
for a students projects we are working with Pentaho CDE to create a dashboard. At first it works fine, but now we are hanging at the point adding more than one Select Component. We inserted the Parameters of the Select Components to the SQL-Queries in the Where statement but now we have the problem, that it is not possible to select all elements in one select component and only one in the others. The sample space is getting smaller and smaller the more parameters we add because we can't find out how to select all option in one select component and send this all to the query. Is it possible in
