LIZ DB / News: Recent posts

Contribute to the LIZ DB project!

LIZ DB is a non-commercial open-source project, developed under the PHP License that can be used and modified freely by everyone.

LIZ DB currently provides implementation of its interfaces only for MySQL5 database.

I encourage every developer that finds LIZ DB database connectivity approach attractive to write implementations for other vendors like PostgreSQL, Oracle, IBM DB2, and other.

I'm looking forward to hear from You!
best regards
