Analyze UKG Pro WFM Data in R via JDBC
Access UKG Pro WFM data with pure R script and standard SQL on any machine where R and Java can be installed. You can use the CData JDBC Driver for UKG Pro WFM and the RJDBC package to work with remote UKG Pro WFM 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 UKG Pro WFM and visualize UKG Pro WFM data by calling standard R functions.
Install R
You can match the driver's performance gains from multi-threading and managed code by running the multithreaded Microsoft R Open or by running open R linked with the BLAS/LAPACK libraries. This article uses Microsoft R Open 3.2.3, which is preconfigured to install packages from the Jan. 1, 2016 snapshot of the CRAN repository. This snapshot ensures reproducibility.
Load the RJDBC Package
To use the driver, download the RJDBC package. After installing the RJDBC package, the following line loads the package:
library(RJDBC)
Connect to UKG Pro WFM as a JDBC Data Source
You will need the following information to connect to UKG Pro WFM as a JDBC data source:
- Driver Class: Set this to cdata.jdbc.api.APIDriver
- Classpath: Set this to the location of the driver JAR. By default this is the lib subfolder of the installation folder.
The DBI functions, such as dbConnect and dbSendQuery, provide a unified interface for writing data access code in R. Use the following line to initialize a DBI driver that can make JDBC requests to the CData JDBC Driver for UKG Pro WFM:
driver <- JDBC(driverClass = "cdata.jdbc.api.APIDriver", classPath = "MyInstallationDir\lib\cdata.jdbc.api.jar", identifier.quote = "'")
You can now use DBI functions to connect to UKG Pro WFM and execute SQL queries. Initialize the JDBC connection with the dbConnect function.
Start by setting the Profile connection property to the location of the UKGProWFM Profile on disk (e.g. C:\profiles\UKGProWFM.apip). Next, set the ProfileSettings connection property to the connection string for UKGProWFM (see below).
UKGProWFM API Profile Settings
UKG Pro Workforce Management uses OAuth 2.0 with the Resource Owner Password Credentials grant (grant_type=password) to authorize access to the API. Unlike most OAuth-based profiles, this does not use a browser redirect/authorization-code step: the driver exchanges your UKG Pro WFM username, password, client ID, and client secret directly for an access token.
Set the following connection properties to authenticate:
- AuthScheme: Set this to OAuthPassword.
- Host: Set this to the hostname of your UKG Pro Workforce Management datacenter/tenant (for example, yourcompany.mykronos.com). Do not include the protocol (https://) or a trailing slash.
- OAuthClientId: Set this to the client ID issued for your UKG Pro Workforce Management OAuth application.
- OAuthClientSecret: Set this to the client secret issued for your UKG Pro Workforce Management OAuth application.
- User: Set this to your UKG Pro Workforce Management username.
- Password: Set this to your UKG Pro Workforce Management password.
Access tokens are obtained from https://{Host}/api/authentication/access_token. Refresh tokens issued by UKG Pro Workforce Management expire after 7 days; if a refresh attempt fails because the refresh token itself has expired, the driver must re-authenticate with your User/Password credentials to obtain a new access token.
Built-in Connection String Designer
For assistance in constructing the JDBC URL, use the connection string designer built into the UKG Pro WFM JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.
java -jar cdata.jdbc.api.jar
Fill in the connection properties and copy the connection string to the clipboard.
Below is a sample dbConnect call, including a typical JDBC connection string:
conn <- dbConnect(driver,"jdbc:api:Profile=C:\profiles\UKGProWFM.apip;AuthScheme=OAuthPassword;ProfileSettings='Host=yourcompany.mykronos.com;User=your_username;Password=your_password;';OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;")
Schema Discovery
The driver models UKG Pro WFM APIs as relational tables, views, and stored procedures. Use the following line to retrieve the list of tables:
dbListTables(conn)
Execute SQL Queries
You can use the dbGetQuery function to execute any SQL query supported by the UKG Pro WFM API:
employees <- dbGetQuery(conn,"SELECT PersonNumber, UserName FROM Employees WHERE PersonId = '12345'")
You can view the results in a data viewer window with the following command:
View(employees)
Plot UKG Pro WFM Data
You can now analyze UKG Pro WFM 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(employees$UserName, main="UKG Pro WFM Employees", names.arg = employees$PersonNumber, horiz=TRUE)
