Link Visio Shapes to Amazon Athena Data

Automatically update Amazon Athena data with the changes you make to Visio master shapes.

Automate the process of entering data into Visio diagrams and keeping your diagrams up to date with the CData ODBC Driver for Amazon Athena. The driver surfaces Amazon Athena data as an ODBC data source that can be accessed by applications with built-in ODBC support like Microsoft Office. This article shows how to create a simple diagram to start brainstorming about Visio projects linked to Amazon Athena data.

Connect to Amazon Athena as an ODBC Data Source

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.

Authenticating to Amazon Athena

To authorize Amazon Athena requests, provide the credentials for an administrator account or for an IAM user with custom permissions: Set AccessKey to the access key Id. Set SecretKey to the secret access key.

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

Obtaining the Access Key

To obtain the credentials for an IAM user, follow the steps below:

  1. Sign into the IAM console.
  2. In the navigation pane, select Users.
  3. To create or manage the access keys for a user, select the user and then select the Security Credentials tab.

To obtain the credentials for your AWS root account, follow the steps below:

  1. Sign into the AWS Management console with the credentials for your root account.
  2. Select your account name or number and select My Security Credentials in the menu that is displayed.
  3. Click Continue to Security Credentials and expand the Access Keys section to manage or create root account access keys.

Authenticating from an EC2 Instance

If you are using the CData Data Provider for Amazon Athena 2018 from an EC2 Instance and have an IAM Role assigned to the instance, you can use the IAM Role to authenticate. To do so, set UseEC2Roles to true and leave AccessKey and SecretKey empty. The CData Data Provider for Amazon Athena 2018 will automatically obtain your IAM Role credentials and authenticate with them.

Authenticating as an AWS Role

In many situations it may be preferable to use an IAM role for authentication instead of the direct security credentials of an AWS root user. An AWS role may be used instead by specifying the RoleARN. This will cause the CData Data Provider for Amazon Athena 2018 to attempt to retrieve credentials for the specified role. If you are connecting to AWS (instead of already being connected such as on an EC2 instance), you must additionally specify the AccessKey and SecretKey of an IAM user to assume the role for. Roles may not be used when specifying the AccessKey and SecretKey of an AWS root user.

Authenticating with MFA

For users and roles that require Multi-factor Authentication, specify the MFASerialNumber and MFAToken connection properties. This will cause the CData Data Provider for Amazon Athena 2018 to submit the MFA credentials in a request to retrieve temporary authentication credentials. Note that the duration of the temporary credentials may be controlled via the TemporaryTokenDuration (default 3600 seconds).

Connecting to Amazon Athena

In addition to the AccessKey and SecretKey properties, specify Database, S3StagingDirectory and Region. Set Region to the region where your Amazon Athena data is hosted. Set S3StagingDirectory to a folder in S3 where you would like to store the results of queries.

If Database is not set in the connection, the data provider connects to the default database set in Amazon Athena.

Connect Amazon Athena Data to Diagrams

Follow the steps below to use the Data Selector Wizard to import data into your diagram.

  1. Open Visio and click File -> New. Open the Brainstorming template.
  2. On the Data tab, click Link Data to Shapes.
  3. Select the ODBC option and select ODBC DSN.
  4. Select the DSN for Amazon Athena, select the table you want to import, and finish the wizard. This article uses Customers as an example.

Link Amazon Athena Entities to Shapes

Follow the steps below to create a simple diagram that shows how to create shapes from your data, one of the ways to link Amazon Athena entities to shapes:

  1. Click Brainstorming Shapes and drag a main topic onto the drawing page. Enter Customers as the text of the main topic.
  2. Click Topic.
  3. Select a row in the External Data window and drag it onto the drawing page.
  4. Right-click the Topic shape and click Data -> Edit Data Graphic.
  5. Click New Item.
  6. In the Data Field menu, select a column. In the Displayed As menu, select how to display them.
  7. Drag a few other Amazon Athena entities onto the drawing page and add association lines back to the main topic, Customers. New topics have the same configuration: Numeric columns displayed in data bars stand out in contrast to other Customers entities.

You can refresh your diagram from the Data tab, synchronizing your shapes with the external Amazon Athena data.
