Build EnterpriseDB-Connected Dashboards 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 EnterpriseDB data for visualizations, dashboards, and more. This article shows how to create a virtual database for EnterpriseDB and build visualizations from EnterpriseDB data in Redash.

CData Connect Server provides a pure SQL Server interface for EnterpriseDB, allowing you to easily build reports from live EnterpriseDB 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 EnterpriseDB, leveraging server-side processing to quickly return the requested EnterpriseDB data.

Create a Virtual SQL Server Database for EnterpriseDB Data

CData Connect Server uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

1. Login to Connect Server and click Connections.
2. Select "EnterpriseDB" from Available Data Sources.
3. Enter the necessary authentication properties to connect to EnterpriseDB.

   The following connection properties are required in order to connect to data.

   • Server: The host name or IP of the server hosting the EnterpriseDB database.
   • Port: The port of the server hosting the EnterpriseDB database.

   You can also optionally set the following:

   • Database: The default database to connect to when connecting to the EnterpriseDB Server. If this is not set, the user's default database will be used.

   Connect Using Standard Authentication

   To authenticate using standard authentication, set the following:

   • User: The user which will be used to authenticate with the EnterpriseDB server.
   • Password: The password which will be used to authenticate with the EnterpriseDB server.

   Connect Using SSL Authentication

   You can leverage SSL authentication to connect to EnterpriseDB data via a secure session. Configure the following connection properties to connect to data:

   • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
   • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
   • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
   • SSLClientCertType: The certificate type of the client store.
   • SSLServerCert: The certificate to be accepted from the server.
4. Click Save Changes
5. 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 EnterpriseDB data from Redash.

Visualize EnterpriseDB Data in Redash

The steps below outline creating a new data source in Redash based on the virtual EnterpriseDB database in Connect Server and building a simple visualization from the data.

Create a New Data Source

1. Log into Redash, click on your profile and click "Data Sources"
2. Click the " New Data Source" button
3. Select "Microsoft SQL Server" as the Data Source Type
4. On the configuration tab, set the following properties:
   • Name: Name the data source (e.g. EnterpriseDB (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 EnterpriseDB (e.g. EnterpriseDB1)
   • Click the checkbox to Use SSQL
5. Click Create
6. 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 EnterpriseDB data.

Create a EnterpriseDB Data Visualization

1. Click Create -> New Query
2. Select the newly created Data Source (you can explore the data structure in the New Query wizard)
3. Write a SQL statement to retrieve the data, for example:
   SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'
4. Click the "Execute" button to load EnterpriseDB data into Redash via CData Connect
5. Use the Visualization Editor to create and analyze graphs from EnterpriseDB data
6. You can schedule the query to refresh and update the visualization periodically

SQL Access to EnterpriseDB Data from Cloud Applications

At this point, you have a direct, cloud-to-cloud connection to EnterpriseDB data from Redash. You can create new visualizations, build dashboards, and more.
