    typically, in programing
    global and local variables refer to the scope of a variable.

    global variables persist throughout some section of code where local variables persist throughout a smaller subset of the code.

    in oracle you can have a package that defines a global variable and is available throughout all procedures in that package but if you define a variable within one of the procedures in that package that variable is local and available only to that procedure.
