Use CData Connect Server to create a virtual SQL Server Database for MarkLogic data and build visualizations and dashbaords from MarkLogic data in Redash.
Redash lets you connect and query your data sources, build dashboards to visualize data and share them with your company. When paired with CData Connect Server, you get instant, cloud-to-cloud access to MarkLogic data for visualizations, dashboards, and more. This article shows how to create a virtual database for MarkLogic and build visualizations from MarkLogic data in Redash.
CData Connect Server provides a pure SQL Server interface for MarkLogic, allowing you to easily build reports from live MarkLogic data in Redash — without replicating the data to a natively supported database. As you build visualizations, Redash generates SQL queries to gather data. Using optimized data processing out of the box, CData Connect Server pushes all supported SQL operations (filters, JOINs, etc) directly to MarkLogic, leveraging server-side processing to quickly return the requested MarkLogic data.
Create a Virtual SQL Server Database for MarkLogic Data
CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.
- Login to Connect Server and click Connections.
- Select "MarkLogic" from Available Data Sources.
-
Enter the necessary authentication properties to connect to MarkLogic.
Set User, Password, and Server to the credentials for the MarkLogic account and the address of the server you want to connect to. You should also specify the REST API Port if you want to use a specific instance of a REST Server.
- Click Save Changes
- Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.
With the virtual database created, you are ready to connect to MarkLogic data from Redash.
Visualize MarkLogic Data in Redash
The steps below outline creating a new data source in Redash based on the virtual MarkLogic database in Connect Server and building a simple visualization from the data.
Create a New Data Source
- Log into Redash, click on your profile and click "Data Sources"
- Click the " New Data Source" button
- Select "Microsoft SQL Server" as the Data Source Type
- On the configuration tab, set the following properties:
- Name: Name the data source (e.g. MarkLogic (CData Connect))
- Host: The full URL to your CData Connect instance (e.g. https://connect_server_url)
- Port: The port of the CData Connect SQL Server endpoint (e.g. 1433)
- User: A CData Connect user
- Password: The password for the above user
- Database name: The name of the virtual database for MarkLogic (e.g. MarkLogic1)
- Click the checkbox to Use SSQL
- Click Create
- Click the "Test Connection" button to ensure you have configured the connection properly
With the new Data Source created, we are ready to visualize our MarkLogic data.
Create a MarkLogic Data Visualization
- Click Create -> New Query
- Select the newly created Data Source (you can explore the data structure in the New Query wizard)
- Write a SQL statement to retrieve the data, for example:
SELECT Name, TotalDue FROM Customer
- Click the "Execute" button to load MarkLogic data into Redash via CData Connect
- Use the Visualization Editor to create and analyze graphs from MarkLogic data
- You can schedule the query to refresh and update the visualization periodically
SQL Access to MarkLogic Data from Cloud Applications
