Tpda3 is a classic desktop database application framework and run-time, written in Perl. Has PerlTk and (experimental) wxPerl support for the GUI part and Firebird, PostgreSQL, SQLite and CUBRID (new) support for the RDBMS.
Tpda3 is the successor of TPDA and, hopefully, has a much better API implementation. The look and the user interface functionality of Tpda3 is almost the same as of TPDA, with some minor improvements.
