| 1. Goal | |
| This document summarizes the steps required to validate the data set generated | |
| by DBGEN, relative to the reference data published by the TPC. | |
| 2. Pre-Requesites | |
| Toolset executable: This readme file is included as part of the toolset | |
| distributed by the TPC. The DBGEN and QGEN executables must be built from | |
| the same distribution. | |
| Reference Data Set(s): For each permissible scale factor, the TPC has | |
| produced a separate zip file that defines the reference point for the base | |
| data set, the update data set, and the output of QGEN. These must be | |
| downloaded separately from the TPC web site. | |
| 3. Validation Process | |
| a. Setup | |
| The commands that are included in this distribution assume that they are | |
| being executed from <DBGEN>/reference, where <DBGEN> is directory into which | |
| the DBGEN distribution was unpacked. If that is not the case for your | |
| environemnt, the paths to executables and associated files will need to be | |
| edited to match your directory structure. | |
| b. Base Data Validation | |
| The base data set is produced using cmd_base_sf<n> where <n> is the scale | |
| factor to be generated. The resulting files will be produced in the current | |
| working directory. The generated files will be of the form <name>.tbl.<nnn>, | |
| where <name> will is the name of one of the tables in the TPCH schema, and | |
| <nnn> identifies a particular data generation step. | |
| The file set produced by genbaserefdata.sh should match the <name>.tbl.<nnn> | |
| files found in the reference data set for the same scale factor. | |
| c. Update Data Validation | |
| The update data set is produced using cmd_update_sf<n> where <n> is the scale | |
| factor to be generated. The resulting files will be produced in the current | |
| working directory. The generated files will be of the form | |
| <name>.tbl.u<mmm>.<nnn> and delete.u<nnn>.<mmm>, where <name> will is the | |
| name of one of the tables in the TPCH schema, and <mmm> and <nnn> identify | |
| a particular data generation step. | |
| For each file produced by DBGEN, the first 100 lines of the file should | |
| match the delete.tbl.u<nnn>.<mmm> and <name>.tbl.u<nnn>.<mmm> files found in the | |
| reference data set. Where the files from the reference data set contain | |
| fewer than 100 lines, the file should match in their entriety. | |
| d. QGEN Parameter Generation | |
| The qgen paramter sets are produced using the cmd_qgen_sf<n> files, where | |
| <n> matches the scale factor being validated. The resulting files will | |
| be produced in the current working directory. The generated files will be of | |
| the form subparam_<nnn>, where <nnn> identifies a particular qgen subsituttion | |
| set. | |
| The file set produced by cmd_qgen_<sf> script should match the subparam.<nnn> | |
| files found in the reference data set. | |
