Analyze Adobe Experience Manager Data in R via ODBC

Access Adobe Experience Manager data with pure R script and standard SQL. You can use the CData ODBC Driver for Adobe Experience Manager and the RODBC package to work with remote Adobe Experience Manager data in R. By using the CData Driver, you are leveraging a driver written for industry-proven standards to access your data in the popular, open-source R language. This article shows how to use the driver to execute SQL queries to Adobe Experience Manager data and visualize Adobe Experience Manager data in R.

Install R

You can complement the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open (MRO).

Connect to Adobe Experience Manager as an ODBC Data Source

Information for connecting to Adobe Experience Manager follows, along with different instructions for configuring a DSN in Windows and Linux environments.

The driver connects to Adobe Experience Manager (AEM) instances that expose the JCR repository over WebDAV. It supports both on-premises AEM and AEM as a Cloud Service deployments.

To establish a connection, set the following properties:

• URL: The WebDAV-enabled JCR server URL.
  • AEM as a Cloud Service: https://author-pXXXXX-eXXXXX.adobeaemcloud.com/crx/server
  • Local development: http://localhost:4502/crx/server
• User: Your AEM username.
• Password: Your AEM password.

Note: Tables are dynamically generated based on the JCR repository structure. Ensure that the configured user has sufficient permissions to access the required content paths in the AEM repository.

When you configure the DSN, you may also want to set the Max Rows connection property. This will limit the number of rows returned, which is especially helpful for improving performance when designing reports and visualizations.

Windows

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.

Linux

If you are installing the CData ODBC Driver for Adobe Experience Manager in a Linux environment, the driver installation predefines a system DSN. You can modify the DSN by editing the system data sources file (/etc/odbc.ini) and defining the required connection properties.

/etc/odbc.ini

[CData AdobeExperienceManager Source]
Driver = CData ODBC Driver for Adobe Experience Manager
Description = My Description
URL = https://author-p12345-e67890.adobeaemcloud.com/crx/server
User = admin
Password = admin

For specific information on using these configuration files, please refer to the help documentation (installed and found online).

Load the RODBC Package

To use the driver, download the RODBC package. In RStudio, click Tools -> Install Packages and enter RODBC in the Packages box.

After installing the RODBC package, the following line loads the package:

library(RODBC)

Note: This article uses RODBC version 1.3-12. Using Microsoft R Open, you can test with the same version, using the checkpoint capabilities of Microsoft's MRAN repository. The checkpoint command enables you to install packages from a snapshot of the CRAN repository, hosted on the MRAN repository. The snapshot taken Jan. 1, 2016 contains version 1.3-12.

library(checkpoint)
checkpoint("2016-01-01")

Connect to Adobe Experience Manager Data as an ODBC Data Source

You can connect to a DSN in R with the following line:

conn <- odbcConnect("CData AdobeExperienceManager Source")

Schema Discovery

The driver models Adobe Experience Manager APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:

sqlTables(conn)

Execute SQL Queries

Use the sqlQuery function to execute any SQL query supported by the Adobe Experience Manager API.

content <- sqlQuery(conn, "SELECT Id, Name FROM Content WHERE Name = 'example'", believeNRows=FALSE, rows_at_time=1)

You can view the results in a data viewer window with the following command:

View(content)

Plot Adobe Experience Manager Data

You can now analyze Adobe Experience Manager data with any of the data visualization packages available in the CRAN repository. You can create simple bar plots with the built-in bar plot function:

par(las=2,ps=10,mar=c(5,15,4,2))
barplot(content$Name, main="Adobe Experience Manager Content", names.arg = content$Id, horiz=TRUE)
