I'm not experienced in using ORMs or the architectures being discussed here, but it seems to me that problems might arise if the database structure is too hidden from the people writing and maintaining an application.

How do you maintain transactional integrity in a situation where Perl objects reference multiple tables and different Perl objects might have overlapping table references? It seems to me that sometimes, you want to make sure that a number of Objects being updated result in the database tables being updated atomically and not understanding the impact on the underlying tables might lead one to believe this is being done when it's not. Conversely, you might only want to operate on a single object and have that update the table without waiting on operations on associated objects.

Forgive me if I'm speaking from ignorance of the tools.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
