=============Steps for setting up DB and running benchmarks=============

Follow the steps below for generating db for SSB and TBC-H:

• Clone https://github.com/electrum/ssb-dbgen for SSB and https://github.com/electrum/tpch-dbgen for TPCH.
• run make clean from inside the cloned repositories.
• run make all.
• run ./dbgen -s <scale_factor> -T a to generate tables. We have used 1 for TPC-H and 4 for SSB. 

Follow the steps for running benchmarks on PostgreSQL

• Change the path SSB_TABLE_FILES_DIR in ssb/postgres/config.sh and TPCH_TABLE_FILES_DIR in ssb/postgres/config.sh  to point to local SSB and TPC-H directories respectively db location. 
• run ./load.sh (This creates the schema and loads data into the schema in PG and adds foreign key constraints.)

Note: Data in the existing table files may not adhere to Postgres formatting due to stray ‘|’ at the end of rows. Use "for i in ls *.tbl; do sed 's/|$//' $i > ${i/tbl/csv}; echo $i; done;” to format the data.  

• Run queries using ./run-queries.sh

Follow the steps for running benchmarks on SQLite  

• Change the path SSB_TABLE_FILES_DIR in ssb/sqlite/config.sh and TPCH_TABLE_FILES_DIR in ssb/sqlite/config.sh  to point to local SSB and TPC-H directories respectively db location. 
• Change SQLITE_DB_PATH path in ssb/sqlite/config.sh and  tpch/sqlite/config.sh to point to desired location of sqlite db creation. 
• run ./load.sh. This will generate the .db files for sqlite. 
• run queries ./run-queries.sh
