Hello Dieter,

As i realize, ZSQL methods are merely SQL statements for data
manipulation - select, insert, delete and so on. But some application
logic and data integrity rules may be IMHO wrapped into ZClasses
instead of triggers and stored procedures. It looks promising for
instance to have base class Patient (with appropriate ZSQL methods),
which can produce other classes like Patient with knee problems,
Patient for total arthroplasty and so on, where properties of base
class including ZSQL are inherited and require minimal
additions/changes. Do i suppose wrong?
