Data Puppy Lite is a database migration tool for Oracle, MySQL, SQL Server & PostgreSQL that demonstrates the basic capabilities of Cirro's full blown and highly scalable database migration product. The key benefit of this product is ease of use. You can easily migrate from one database to another with minimal effort. This product only handles the four databases stated, is not threaded (i.e. runs serially) and also requires the Windows PC to fetch and then write the data which is OK for local databases, but could stress a shared network. If you need more than what this freeware provides, then look at Cirro's full blown Data Puppy product.
