A MySQL AB disponibilizou a versão 5.0 do banco de dados usado por 44% dos desenvolvedores que usam banco de dados.

Este release vem com tudo que faltava no mysql. São eles:

# Stored Procedures and SQL Functions -- to embed business logic in the database and improve performance;
# Triggers -- to enforce complex business rules at the database level;
# Views -- to ensure protection of sensitive information;
# Cursors -- to allow easier database development and reference of large datasets;
# Information Schema -- to provide easy access to metadata;
# XA Distributed Transactions -- supports complex transactions across multiple databases in heterogeneous environments;
# end more...

Vale a pena dar uma olhada.
