Viewing MongoDB Data in RAD Studio Data Explorer


How to view MongoDB data in RAD Studio Data Explorer using the CData ODBC Driver for MongoDB.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for MongoDB, you gain access to live MongoDB data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update MongoDB data. This article will walk through connecting to MongoDB using the Data Explorer.

Configure a Connection to MongoDB

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Set the Server, Database, User, and Password connection properties to connect to MongoDB. To access MongoDB collections as tables you can use automatic schema discovery or write your own schema definitions. Schemas are defined in .rsd files, which have a simple format. You can also execute free-form queries that are not tied to the schema.

Connecting to MongoDB Data Using Data Explorer

You can create a simple application for displaying MongoDB data by utilizing the CData FireDAC Components for MongoDB and a new VCL Forms Application:

  1. Open the Data Explorer in RAD Studio and expand FireDAC.
  2. Right-click the ODBC Data Source node in the Data Explorer.
  3. Click Add New Connection.
  4. Enter a name for the connection.
  5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for MongoDB.
  6. Back in the Data Explorer, expand the tables for the connection.

  7. Create a new VCL Forms application and drag a table (for example: restaurants) onto the form.

  8. Select the restaurantsTable object on the form and set the Active property to true.

  9. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

  10. Arrange the TStringGrid on the form and run the application to see the restaurants data.
