Viewing Cassandra Data in RAD Studio Data Explorer

How to view Cassandra data in RAD Studio Data Explorer using the CData FireDAC Components for Cassandra.

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

Connecting to Cassandra Data Using Data Explorer

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

  1. Open the Data Explorer in RAD Studio and expand FireDAC.
  2. Right-click on CData Cassandra Data Source and click Add New Connection.

  3. Name the connection.
  4. Fill in the necessary connection parameters and click OK.

    Cassandra への接続には、Server、Port、Database を接続プロパティとして設定します。追加で、内部認証を使う場合には、User、Password を接続プロパティに設定します。

  5. Back in the Data Explorer, expand the tables for the connection.
  6. Create a new VCL Forms application and drag a table (for example: Customer) onto the form.

  7. Select the CustomerTable object on the form and set the Active property to true.
  8. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

  9. Arrange the TStringGrid on the form and run the application to see the Customer data.
