Parse::Dia::SQL - Convert Dia class diagrams into SQL.
use Parse::Dia::SQL; my $dia = Parse::Dia::SQL->new( file => 't/data/TestERD.dia', db => 'db2' ); print $dia->get_sql(); # or command-line version perl parsediasql --file t/data/TestERD.dia --db db2
Dia is a diagram creation program for Linux, Unix and Windows released under the GNU General Public License.
Parse::Dia::SQL converts Dia class diagrams into SQL.
Parse::Dia::SQL is the parser that interprets the .dia file(s) into an internal datastructure.
Parse::Dia::SQL::Output (or one of its sub classes) can take the datastructure and generate the SQL statements it represents.
Index options are supported. Text is taken from the comments field of the operation, i.e. the index. A database specific default value is used if the comments field is left blank. Consult the Output sub class' constructor.
Type mapping is supported. A type mapping is a user-defined column name replacement. Unlike tedia2sql the type mapping is non-recursive. Consult
t/data/typemap.diafor an example.
Preliminary support for Dia's database shapes is added.
Table comments are used as table postfix options. This means per-table options (e.g. partitioning options) are supported on a per-database level.
backticks notation is supported for MySQL-InnoDB.
Parse::Dia::SQL has been tested with Dia versions 0.93 - 0.97.
Parse::Dia::SQL uses the XML
version tag information in the .dia input file to determine how each XML construct is formatted. Future versions of Dia may change the internal format, and XML
version tag is used to detect such changes.
The following databases are supported:
- SQLite3fk (with foreign key support)
- MySQL InnoDB
- MySQL MyISAM
Adding support for additional databases means to create a subclass of Parse::Dia::SQL::Output.
Patches are welcome.
Parse::Dia::SQL is based on tedia2sql by Tim Ellis and others. See the AUTHORS file for details.
