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. | |
