Cube
Talk to the OLAP based backend via XMLA SOAP messages from Ruby. You can send (simple) MDX queries and get the result back in a human friendly from.
Installation
Add to Gemfile
gem 'cube'
Configuration
Set up your catalog and endpoint
XMLA.configure do |c|
c.catalog = "OUTAGE"
c.endpoint = "http://localhost:8383/mondrian/xmla"
end
Querying the OLAP
table = XMLA::Cube.execute <<-MDX
SELECT [Location].[City].children on COLUMNS,
[Measures].[Count] on ROWS
FROM [OUTAGE]"
MDX
Table has two attributes: header and rows.
Scalar results
average_mtbf = XMLA::Cube.execute_scalar <<-MDX
SELECT {Hierarchize({[Measures].[MTBF]})} ON COLUMNS
FROM [OUTAGE]
WHERE [Country].[Croatia]
MDX
Limitations
- No drill down (fails to even parse the result)
- No multi named columns
- Tested only with icCube and Mondrian XMLA, in theory works with every XMLA provider
Contributing to cube
- Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet
- Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it
- Fork the project
- Start a feature/bugfix branch
- Commit and push until you are happy with your contribution
- Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.
- Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
