This is a web site of YYnet Communications ("YYnet").
It is set up to highlight YYnet's programming and support services
for the following database systems:

Alpha Four (Alpha Software Company)

SQL Server (Microsoft)

Access (Microsoft)

YYnet is one of few companies which still provide support to Alpha Four,
a DOS-based database language.

Alpha Four is similar to dBase, but
much easier to use.  It gained popularity quickly around the time when Microsoft started to introduce Windows.
Today many for-profit corporations and non-profit organizations as well
continue to use Alpha Four applications developed years ago.
