NAME

DBIO::Firebird::Diff - Compare two introspected Firebird models

VERSION

version 0.900000

DESCRIPTION

DBIO::Firebird::Diff compares two introspected Firebird database models (as produced by DBIO::Firebird::Introspect) and produces a list of structured diff operations. These operations can then be rendered to SQL or a human-readable summary.

my $diff = DBIO::Firebird::Diff->new(
    source => $current_model,
    target => $desired_model,
);

if ($diff->has_changes) {
    print $diff->as_sql;
    print $diff->summary;
}

Diff operations are generated in dependency order: tables first, then columns, then indexes.

• DBIO::Firebird::Deploy - orchestrates introspection and diff

• DBIO::Firebird::Introspect - produces the models being compared
