|
-- combined all typedefs in one header: dsstypes.h
|
|
-- combined flat file generation in print.ec
|
|
-- combined typedef population in build.ec
|
|
-- added -P to control rowcnt scaling (P for percentage)
|
|
-- added -D option for Direct data generation and added
|
|
appropriate hooks in tdefs[] structure
|
|
-- added -F option for flat file generation
|
|
-- reused -T option (use -P 0.1 to build test size database)
|
|
now accepts suboptions c,o,p,s for single table builds.
|
|
-- dropped -M option (scaling is now by rowcount)
|
|
-- added -O option for optional controls. Currently defined:
|
|
-O t -- generate optional time table a join fields in
|
|
order/lineitem
|
|
-O h -- generate headers for flat file output
|
|
-O m -- generate fixed column-length output
|
|
-- removed dynamic memory allocation, redundant calls to
|
|
UnifInt, etc to improve performance
|
|
Changes as of 1/12/92
|
|
-- julian() changed to handle orders->orderdate correctly
|
|
-- rflag distributions corrected in dists.dss
|
|
-- sea, gold removed from color distribution to clean up substring
|
|
problems
|
|
-- part->number and supplier-> adjusted for 1-based indexing
|
|
-- time->day changed to be day of month, not day of year
|
|
-- t.week changed to be week in year, not day of week
|
|
Changes as of 11/18/92
|
|
-- checked line length and tab for transmission
|
|
-- another chapter in the portability wars. added #include
|
|
"machine.h" to dss.h (which is included by everyone else). Any
|
|
machine particular porting changes should go here.
|
|
-- fixed fixed-field formats to prevent double printing
|
|
-- expanded PR_FLT formats to %010.2
|
|
Changes as of 10/21/92
|
|
-- added fixed format and column header handling; users of headers
|
|
will have to define the header functions to be called in
|
|
int (*tdefs.header)()
|
|
Changes as of 10/09/92:
|
|
-- added ansi prototypes and recompiled with gcc -ansi. users may
|
|
need to change the CC definition in the makefile and the contents
|
|
of CFLAGS to reflect their particular ansi compiler.
|
|
-- replaced all int references with long
|
|
-- replaced all float references with double
|
|
-- found and fixed odate/julian problem TS mentioned in 10/09 phone
|
|
call
|
|
|
|
Changes as of 9/09/92:
|
|
-- Park/Miller random number generator included
|
|
-- clerk scaling changed to 100 * scale
|
|
-- parts.name always built from 5 selections from colors set
|
|
-- test scaling changed to ~60MB (TEST_SCALING == 10)
|
|
-- logarithmic scaling removed
|
|
-- mfgcost removed and retail/supplier cost bounds adjusted
|
|
-- agg_str memory leak fixed
|
|
-- independent RNG streams on a per column basis
|

|
|
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.
