Spatio-Bitemporal index workload generator source code
------------------------------------------------------

The high-level description of the generator, its parameters, and the
workloads that it generates can be found in the "Performance Studies"
section of a TimeCenter TR-45 "R-Tree Based Indexing of General
Spatio-Temporal Data."
(http://www.cs.auc.dk/research/DP/tdb/TimeCenter/TimeCenterPublications/TR-45.ps.gz)

The generator can be compiled using the provided make file. It
compiles with GNU C++.

A sample generator parameters file test.prm is provided. Comments are
provided in test.prm describing individual parameters. One of the
parameters is a name of a spatial data file. The format of this file
should follow the format used by the A La Carte
(http://www-inf.enst.fr/~bdtest/sigbench/menu.html) spatial data
generator. A sample file (generated by A La Carte) is provided
(spdata.dat).

Start the generator by typing:

./generate test.prm   

or 

./generate -t test.prm

In both cases test.sql is output. In the first case the output is a
binary file, in the second - a readable text file.

The .sql file contains commands to the index:

t intvalue 
   Changes the current time to intvalue 
a         
   Advances the time by 1
i (tt1, vt1, tt2|UC, vt2|NOW, delta, x1, y1, x2, y2), integer_key
   Inserts a spatio-bitemporal entry into the index
d =(tt1, vt1, tt2|UC, vt2|NOW, delta, x1, y1, x2, y2)
   Deletes an entry from the index  
s &(tt1, vt1, tt2, vt2, x1, y1, x2, y2)
   Performs a rectangular spatio-bitemporal intersection query
