UMRA can work with a wide variety of data sources, such as flat files (CSV), LDAP systems, and any ODBC-compliant database. Data from these sources are pulled into UMRA as in-memory tables, which can then be leveraged inside of your project or exported to a CSV file.
Any time you want to pull data into UMRA, you will need to use the Generate Generic Table action (Variable Actions > Table). This action gives you the option to connect to one of any number of different data sources, and store the retrieved information in a script variable.
If you are connecting to a ODBC-compliant database, you may need to work with your database administrator to acquire the proper credentials and queries to retrieve the information that you desire.
