Re: [slang-users] Slang modules and threads?

There is a TDBM that is done by the SAMBA group - multiple readers AND writers.

Anyway, Yes I know that relational databases are designed to do that. It is that I
am breaking things down to their simpliest form. Keeping it to simple commands/functions
such as ye old COBOL uses:

Read, Read Next, Read Previous ,Write, Start key, Delete, and the like.
Having fields pushed and poped by:
 slang_attr = GET_ATTR(FD, FIELD_no, MV_NO) ;
 PUSH_ATTR(FD, FIELD_NO, MV_NO, slang_attr) ;
(where FD and Field_no can be Numbers of NAMES, where by the names are converted
to numbers by the function from that data dictionary).

This elminates the "small" users from having their "step-sons first cousin who is
a SQL/DBM expert is coming in to enhance and optimize that SQL database we have. Yeah
he is an expert, done that PLENTY of time on his PS2 and ACCESS database"
(been there , done that, did not like it!).


Sooo.... Now we have the best of both worlds. The runtime and RAD/IDE uses a DBM,
but the Functions could care less about the database backend. They are just pushing and
pop'ing data stacks. But at the simpliest level, the applications can use the DBM
method, whilst allowing the bigger sophisticated users to use a SQL database methods.

Hmm .. which brings up another point, Why does "RELATIONAL" database mean to so many
people that they have a "relative" that is a "DATABASE" expert? ;->
