Big Data

Extract, prepare, and analyze Salesforce.com data using Amazon AppFlow, AWS Glue DataBrew, and Amazon Athena | Amazon Web Services

As organizations embark on their data modernization journey, big data analytics and machine learning (ML) use cases are becoming even more integral parts of business. The ease for data preparation and seamless integration with third-party data sources is of paramount importance in order to gain insights quickly and make critical business decisions faster.

AWS Glue DataBrew is a visual data preparation tool that cleans and normalizes data without writing code. This reduces the time it takes to prepare data for analytics and ML by up to 80% compared to traditional approaches to data preparation.

Software as a service (SaaS) applications play a pivotal role in organizations’ analytics pipelines. This data is essential to include when performing analytics to get insights to make better business decisions. Amazon AppFlow is a fully managed integration service that helps you transfer SaaS data to your data lake securely.

Recently, DataBrew announced native console integration with Amazon AppFlow to connect to data from applications like Salesforce, Zendesk, Slack, ServiceNow, and other SaaS applications, and AWS services like Amazon Simple Storage Service (Amazon S3) and Amazon Redshift. With native integration with Amazon AppFlow, DataBrew is addressing both the challenges with data preparation and seamless integration with SaaS applications.

Salesforce is a popular and widely used customer relationship management (CRM) platform. It lets you store and manage prospect and customer information—like contact info, accounts, leads, and sales opportunities—in one central location. You can derive a lot of useful information by combining the prospect information stored in Salesforce with other structured and unstructured data in your data lake.

In this post, we walk you through how to extract data from Salesforce.com using the native integration that DataBrew has with Amazon AppFlow, prepare the data for your analytical use cases using DataBrew, store it in Amazon S3, and query it with Amazon Athena.

Architecture overview

The following diagram represents the flow described in this post. With the visual point-and-click interface in Amazon AppFlow, you create a new flow with Salesforce as source. You can either use an existing connection to Salesforce or create a new one. In DataBrew, while creating a dataset, you can choose the Amazon AppFlow flow as one of the sources to import the data for data preparation. After you perform the data preparation steps on sample data, you can save the steps as a recipe and automate the flow by creating a DataBrew job by selecting the dataset for the source and the newly created recipe for transformation. The transformed data is published to an S3 bucket. You can use an AWS Glue crawler to catalog that data and use Athena to query the data.

The workflow includes the following steps:

  1. Create an S3 bucket for the raw and transformed data.
  2. Create a connection to Salesforce.
  3. Create a flow to extract the data from Salesforce.com.
  4. Create a dataset and project.
  5. Prepare the data and create a recipe.
  6. Create a job to pull the data from the Amazon AppFlow flow, run the transformations, and load the data in Amazon S3.
  7. Create a crawler to catalog the data.
  8. Analyze data using Athena.

Prerequisites

To implement this solution, you need the following prerequisites:

Now that we have discussed the architecture of our solution, we present the step-by-step instructions.

Create an S3 bucket

To create an S3 bucket, complete the following steps:

  1. On the Amazon S3 console, choose Create bucket.
  2. Enter a name for your bucket; for example, databrew-appflow-data-prep-<your name>.
  3. Choose Create bucket.

Create a connection to Salesforce

If you already have a Salesforce connection created in Amazon AppFlow, you can skip this step. To create a new connection, complete the following steps:

  1. On the Amazon AppFlow console, choose Connections in the navigation pane.

Prepare data and create a recipe

With DataBrew, you can choose from over 250 pre-built transformations to automate data preparation tasks, all without the need to write any code. In this post, we only discuss a few of them. For the full list of transformations, see Recipe step and function reference.

In this step, we split the CloseDate column to CloseYear, CloseMonth, and CloseDay. Then we flag the outliers in the Amount column.

  1. Duplicate the column CloseDate by choosing the column and choosing Duplicate.

  15. For Prefix, enter opportunity_.
  16. Choose Next.
  17. Review the details and choose Finish.
  18. After the crawler is created, select it and choose Run crawler.

The crawler catalogs the data that we uploaded to Amazon S3 after processing using DataBrew.

Analyze data using Athena

When the crawler is complete, we can analyze the data with Athena.

  1. On the AWS Glue console, choose the database we created.
  2. Under Data catalog, choose Tables in databrew-appflow.

You can see a table named opportunity_processed, which points to the Amazon S3 location where the processed data was landed.

  1. Select the table name.
  2. On the Action menu, choose View data.

A pop-up may appear to let you know that you’re going to the Athena console.

  1. Choose Preview data.

If this is the first time using Athena in this account, you have to set the query result location.

  1. Run a query in Athena.

You should be able to see the data in Amazon S3.

You can perform further analysis by running more queries on the data. The following query returns the expected revenue for based on various closeyear and closemonth combinations of opportunities:

SELECT closeyear, closemonth, SUM(expectedrevenue) FROM  "AwsDataCatalog"."databrew-appflow"."opportunity_processed" 
GROUP BY  closeyear, closemonth;

You may want to clean up the demo environment when you are done. To do so, delete the following resources that were created as part of this post:

  • S3 bucket (databrew-appflow-data-prep-<your name>)
  • Connection to Salesforce in Amazon AppFlow (sfdc-appflow)
  • Flow in Amazon AppFlow (salesforce-data)
  • Dataset (databrew-sfdc), project (databrew-appflow-integration), and job (databrew-appflow-job) in DataBrew
  • AWS Glue Data Catalog database (databrew-appflow)
  • IAM role (AWSGlueDataBrewServiceRole-appflow-databrew)

Conclusion

In this post, we walked you through how to extract data from Salesforce.com using the native integration that DataBrew has with Amazon AppFlow. We also demonstrated how to prepare the data for analytical use cases using DataBrew, operationalize the data preparation steps by creating a recipe and use that in a DataBrew job, store the job result in Amazon S3, and query it with Athena.
