How to configure MongoDb data source

  1. Click on "Connect to Database" item at "Cubes" view, or just open this link (ensure that you're logged in).
  2. Select "MongoDb" in Data Source Type selector: MongoDb connection settings form
  3. Fill all required fields:
    Cube Name
    short title that describes this data source
    Connection String
    Valid connection string for MongoDb driver. Example:
    Note: "database" is required if user has access only for specific databases.
    Database Name
    the name of the database to use.
    Collection Name
    the name of collection to use; document and sub-document fields can be used as dimensions or measures in a pivot table reports.
  4. Infer dimensions and measures by columns option: keep it checked to determine dimensions and measures by first N documents - in this case you don't need to define Dimensions and Measures by yourself. You can edit configuration later and remove excessive elements, or customize automatically determined ones.
  5. Click on "Save" button.

If everything is fine you should see a new cube dashboard with the list of available dimensions. In case of connection error you'll see an orange box with the error message.

Dimensions setup

Dimension name should be unique and refer to the document field:

Cube dimensions form
"Field": dimension value is a document field or result of $project specification (provided as first "Parameter").
"Expression": custom formula that uses another dimensions as arguments (specified in "Parameters").
Unique dimension identifier. For Type=Field this is document or sub-document field specifier.
User-friendly dimension title displayed on UI (optional).
Custom format string (.NET String.Format) for dimension values (optional). Examples:
  • for number values: ${0:0.##} → $10.25
  • for date values: {0:yyyy-MM-dd} → 2017-05-25
For Type=Field: you can specify custom $project specification. For example: {$year:"$create_date"} (extracts year value from "create_date" field).
For Type=Expression: you can specify custom formula (1-st parameter) and dimension names for the arguments (2-nd, 3-rd etc parameter).
