 Topspeed vs Unix Based DB

We are wondering if it is possible to convert the database on a finished
application from topspeed to a unix based database such as PHP and
MySql.  What are the consequences?
What are the risks?

Thanks,
Arnold

Arnold,
The issue is based on the risk of addressing specific data using datasets
that are non-specific; ie not unique. Its OK to do that using TPS but not
using SQL, primarily because the unique Row-ID is not passed over to the
Clarion environment. Thats why TPS is so easy to develop on. Read up on the
SQL language and understand it well, then consider the implications of
accessing SQL data using your dictionary defined keys only - in other words
the "where clauses" in the SQL will be generated from the components of the
keys that you use in your data. There are also several good articles in
Clarionmag on the subject. Also consider doing the Essentials/Mastery
courses.
