This is the revised data generator for DSS.
The rewrite tried to accomplish three things: (1) identify and isolate
all the implicit assumptions about limits, bounds, ranges, distribu-
tions, etc.; (2) standardize the way any given table was generated/
printed to ease understanding and maintenance; (3) bring the generator
in line with the current work of the committee and the excellent spec
the Indira put together; (4) provide an easy way to adjust distribu-
tions, string contents and to facilitate experimentation to get a
better idea of the impact of data population changes.
The files included are:
driver.c ------- main and the calling routines for the generators
dist.c ------- should really be named dss_util.c; misc routines
customer.c ------- generation and print routines for customer table
orders.c ------- "" "" order table
parts.c ------- "" "" parts/partsupp
suppliers.c ------- "" "" suppliers table
time.c ------- "" "" time table
customer.h ------- associate header files; contain structure
definitions
dss.h dss.h holds the large number of assumptions and
orders.h values that have been used as IFDEFs.
parts.h
suppliers.h
time.h
dists.dss ------- string selections and weights; used to build
distributions
Running make will create an executable (using the compiler flags in
CFLAGS, the ld flags in LDFLAGS and the libraries in LIBS [-O, -s,
and -lm by default]) which will create flat files suitable for dbload.
