Systems and methods for matching data variables across different data domains are disclosed. An example method includes: identifying a first data parameter included in a first programming statement; selecting a mapping file that includes one or more mappings between parameters associated with in a first type of programming language and parameters associated with in a second type of programming language. The second type of programming language is different form the first type of programming language. The example method further includes identifying, based on the one or more mappings, second one or more data parameters associated with a second programming statement; receiving a user section of the first data parameter; and responsive to the user section, presenting the second one or more data parameters to a user.
