How can use another database instead of foodmart

Question

I am not much familiar with saiku reporting. When I run the saiku reporting this display cube for foodmart db. But I want to use database from postgresql. For that I made one connection file. Added driver.jar file in to web-inf/lib folder. But I cant seen database in cube.

What we can only use foodmart database ? Cant we use another database?

Answer 1

Sample Data

Create sample data in PostgreSQL:

create table olap_data(id serial, measure int, dim varchar);

insert into olap_data (measure, dim) select * from generate_series(1,10) cross join (values ('a'), ('b'),('c')) a;

select * from olap_data;

Connection File

Add connection file (name does not matter, I'm using dummy_test).

Destination: /saiku-server/tomcat/webapps/saiku/WEB-INF/classes/saiku-datasources/dummy_test

Content:

type=OLAP
name=Financial
driver=mondrian.olap4j.MondrianOlap4jDriver
location=jdbc:mondrian:Jdbc=jdbc:postgresql://localhost:5432/tgr; \
Catalog=/home/Applications/Saiku/saiku-server/tomcat/webapps/saiku/WEB-INF/classes/foodmart/dummy_cube.xml;JdbcDrivers=org.postgresql.Driver;
username=YourUsername
password=YourPassword

Do not forget to set correct connection string, username and password.

Add OLAP schema definition

Destination: /home/Applications/Saiku/saiku-server/tomcat/webapps/saiku/WEB-INF/classes/foodmart/dummy_cube.xml (has to match path defined in data source definition file).

Content:

<Schema name="New Schema1">
  <Cube name="Sample Cube" visible="true" cache="true" enabled="true">
    <Table name="olap_data" schema="public">
    </Table>
    <Dimension type="StandardDimension" visible="true" foreignKey="id" name="Sample Dimension">
      <Hierarchy name="Sample Hiearchy" visible="true" hasAll="true">
        <Table name="olap_data" schema="public">
        </Table>
        <Level name="Sample Level" visible="true" column="dim" uniqueMembers="false">
        </Level>
      </Hierarchy>
    </Dimension>
    <Measure name="Measure" column="measure" aggregator="sum" visible="true">
    </Measure>
  </Cube>
</Schema>

Make it work

Restart Saiku

Clear cache from browser

Now you should see sample cube in Saiku
