Build a Simple VCL Application for AWS Management Data

How to build a simple VCL Application to view AWS Management data in RAD Studio using the CData FireDAC Components for AWS Management.

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData FireDAC Components for AWS Management, you gain access to live AWS Management data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve and update AWS Management data. This article will walk through connecting to AWS Management and creating a simple VCL application with the Form Designer.

Creating a VCL Application for AWS Management Data

The following instructions show how to use the Form Designer to create a simple VCL Forms application that shows the basic FireDAC objects needed to connect to AWS Management from any application.

The following example populates a TDBGrid control.

  1. Create a new VCL Forms Application.
  2. Drop a TFDPhysAWSDataManagementDriverLink and TFDConnection object onto the form.
  3. Double-click the TFDConnection object. The FireDAC Connection Editor is displayed. Select "CData.AWSDataManagement" in the DriverId menu and configure the connection properties.

    To authorize AWSDataManagement requests, provide the credentials for an administrator account or for an IAM user with custom permissions:

    1. Set AccessKey to the access key Id.
    2. Set SecretKey to the secret access key.
    3. Set Region to the region where your AWSDataManagement data is hosted.

    Note: Though you can connect as the AWS account administrator, it is recommended to use IAM user credentials to access AWS services.

  4. Drop a TFDQuery object onto the form and set the properties below:

    • Connection - Set this property to the TFDConnection object, if this object is not already specified.
    • SQL - Click the button in the SQL property and enter a query.
    • Active - Set this property to true.
  5. Drop a TDataSource object onto the form and set the following property:

    • DataSet - In the menu for this property, select the name of the TFDQuery object.
  6. Drop a TDBGrid control onto the form and set the following property:

    • DataSource - Select the name of the TDataSource.
  7. Drop a TFDGUIxWaitCursor onto the form. This is required to avoid a run-time error.

You now have an executable application that displays the results of the SQL Query set in the TFDQuery object.
