It makes sense for you to create connection from a single place of your application, and then pass the connection to the rest (for example your modules).

    But how to I pass a connection? would I do it like
    use DBI; use Module; $dbh- dbi->connect(...); $variable = $packageName->routine($dbh);
    or is there a better way to make the Module Assume that everything called in the main script is useable?
      "or is there a better way to make the Module Assume that everything called in the main script is useable?"

      Unfortunately that is not the better way, many monks here can give a long lecture as why, but let me just make it simple: why should the person call your module know that, inside your module, you expect the connection being named $dbh, not $connection, or $blah?

      so, If I passed $dbh into a method, then that method should beable to access all functions attached to $dbh?

        Yes, when a function gets passed a blessed reference (a reference to an object) then the methods associated with that object are available without explicitly importing them.
